9:54
successfully now what I'm going to do is I'm going to add the record into the database how to add the record into the database what I'm going to do is here
10:01
first this is a we have a uh inside the source package folder we have a folder
10:08
called libraries we have to add the relevant jar file of the MySQL connector right in order to connect MySQL
10:15
connector to Java we have to download the appropriate connector right in order
10:21
to connect the database so what I'm going to do is you just go to the Google and we have to download the MySQL
10:28
connector right I already downloaded if you don't know how to download the MySQL
10:33
connector and all I I already have a videos right uh you just go through my
10:39
the pre previous video i will explain uh from the beginning right okay so I no
10:45
need to explain from the beginning how to download right just select this one i already downloaded i have to get it get
10:51
the one click add jar file this is the files right we have to get it get that
10:58
select both mysq mysql connect connector this both jar files we have to add right
11:03
here it's successfully added you can check here right after that what I going to do is here I'm going to add the
11:10
quotes right so let's go to the source this is the class name this is the
11:16
constructor uh after that we have to write the connection method we have to create the connection method so we have
11:22
write public white we have to create the method
11:27
connect okay we have right first I am going to register the
11:34
MySQL driver here so how to register MySQL driver here is you have to write class dot
11:43
forame you have to write here com dot
11:49
mysql dot jdbc dot
11:56
driver this register driver this is not error it ask to import the try catch
12:04
right After that what I'm going to do is here we have write the connection we have to create the connection objects
12:09
right so we have to write here connection objects
12:14
con write prepare state
12:19
prepared PST you have to add the we don't need to
12:24
add like this simply you have to add here import java dots
12:33
sql we have aster if you have write like the asterk all the classes will be there
12:40
right if you have write like this okay all the SQL classes are reside on this name space if you call this a string
12:47
right this is the perfect one after that what I'm going to have to write con equal driver
12:55
manager dot get connection here we have to write
13:03
JDBC colon MySQL
13:10
colon local host colon what is the database name a
13:18
database this is the online exam you just control C I just copy it control V to paste
13:23
here right here we have to give the user credential of MySQL MySQL right the user
13:33
credential when you install the MySQL connector in your machine the default username will be proved the default
13:40
password will be blank right this is a user credential right so here this is not error you have to import the catch
13:46
catch as well right uh what is the
13:52
problem I write
13:57
here the problem is here I have to uh added the root right root
14:14
You have to write the extra one that's a problem right again the error what is the error
14:21
jdbc MySQL uh local online
14:29
exam
14:38
Right the problem is here we have close the things right okay this is open and
14:44
close that's the problem right now it's okay uh now this is the method right when the when the class is loaded we
14:51
have to call this method ctrl C to copy ctrl V to paste here it is work right that's the stuff we have to do uh now
14:58
let's do the another task is we have to connection method is success uh we have to do the rest of the stuff first we
15:05
have to add the records into the database so we have to select the add button right click event action perform
15:11
here we have to write the add code so how to add the records into the database we have to uh write the things right
15:17
it's very simple uh how to write here is first this text boxes we have to pass
15:25
into the relevant variables to store txt name txt phone number txt address txt so
15:31
we have write string name ST name student name equal
15:38
txt name dot get text get
15:46
text right the same thing C to copyr V to paste here this one should
15:55
be address uh phone number txt
16:02
phone this one should be address string
16:12
address H
16:20
txt right now here what I'm going to do is we have to write uh we have to write
16:26
the page statement right we have PST we have to write here we have to write the insert query so we have write PST equal
16:32
connection dot prepare statement we have to write the insert
16:38
query insert into which table you are going to insert the
16:44
record student table right these are the columns consist of this table so here we
16:52
have to write first insert into student table you have to specify the column
16:59
names student you have to write properly inside the bracket you have to uh
17:05
specify the column names right first one should be the student name so how how you wrote here the same name you have to
17:12
write here right how how you wrote here the same name first name I wrote SD name
17:18
like this second one should be the the sequence of the sequence of rows right so
17:24
here phone address H right phone address H phone
17:31
address H write like this values what
17:37
are values you have to write here four right 1 2 3 question mark four
17:43
question mark right this is the you have to write like this okay after what I'm going to do is see
17:49
here catch block right now write here uh
17:55
PST dot set string one SD
18:02
name after that we have write control C to copy control V to paste here second one should be phone control
18:09
C to copy control V to paste here third one address fourth one edge control C to
18:15
copy control V to paste fourth Right now what I'm going to do is
18:24
[Music]
18:30
here right now here this these are called as parameter this sequence of
18:36
parameters follow the sequence of columns in the database table after that
18:42
we have to write the insert code right so you have to write int k equal pst dot
18:50
execute update right so here you have to write if k equal 1
18:59
mean you have to write the message j option
19:05
ban dot show message
19:13
this you have write record
19:24
add if it is fail mean C copyr V to paste here record add
19:31
fail record fail added fail right add fail okay after add the
19:39
record we have to clear all the text fields So this one Ctrl C to copy ctrl + V to paste here dot set
19:47
text clear you have to write like this the same thing ctrl C to copy control V paste your paste it here paste it here
19:55
thr C copy control bit paste here this one control C copy control bit paste this one control Copy control V paste
20:00
after clear all the cursors will be focused on the txt named text box okay control Copy
20:07
control B the predefined method called request forecast that's it that is the
20:14
thing we have to do very simple right now let's run and check whether it's working fine or
20:21
not right click run
20:35
file right so here another thing is when the form is run it it should be run
20:40
center so select this one properties code generate center now here the
20:46
another thing you have to do here is this very essential stuff uh go to the
20:52
source control F yeah UI
20:58
design here we have change it as a main tab main right now you run the uh design
21:07
and check so very simple here this is the Java format this is actual
21:12
Java this is actual uh string right here it's nice form look right very simple
21:18
now first I'm going to add the student name as John phone number something like that
21:26
address India age uh 23 click add button record add click
21:36
okay you can check here all the fields are clear and here uh curses will be focused on the student name checkbox
21:42
right now you'll be able to check the go to my SQL and see it's working perfectly
21:48
well uh I hope you guys you understood the things well I will continue in my
21:54
next lecture hi friends welcome to tutors funny channel in our last class we saw
22:00
how to add the recordourse in this class I'm going to teach how to view the records and edit and delete the records
22:06
right so let's what what I'm going to do is first I'm going to load the records let's go to the
22:12
source here i'm going to create the method so we have write
22:17
here public
22:23
load here here I'm going to load the student records so I have already written the code so let me change the
22:31
code now let's copy and paste
22:37
it so here we have to do the three we have
22:42
to try paste it cut off past right okay uh
22:50
this is thing you have to write the code right if I return write it uh step by step uh it take too much of time to
22:56
complete the project so that I have already written here this one RS so you have to create the RS object here
23:07
don't worry I'll extend extend it right so okay we have to add the import
23:12
package right that's a thing import now here what I'm going to do is here first I'm going to return the
23:18
prepare statement uh it ask to generate the try and catch you you will be able to generate it after that you have to we
23:24
we have to create the result set object RS RSQL prepare statement uh execute you
23:30
have to write run the query right uh what is the table you are going to load the record I'm going to load the record
23:36
from which table student table this is a table right student
23:46
uh this all the stuff are correct uh we have to load it uh to into j table one
23:52
this j table one so here while loop we have to write the vector we have to
23:59
write the for loop here have to specify Y the column names here what are the column names here this one ID SD name
24:05
phone address and age so we have to write here
24:12
ID SD name phone phone number
24:18
phone and address H you have to write like this
24:25
load that's the thing we have to do this one this load method control C to copy when the form is loaded this method get
24:32
load that's the thing we have right here right now let's I guess all the stuff are correct
24:39
now let's execute the program and check what how to work with this it's working so that all the records are displayed on
24:47
the datab data table successfully uh now what I'm going to do is you have to
24:52
write a code for the edit and delete button first if you want to edit the record select the row which you want to
24:57
edit uh here if you delete the record you have
25:02
to uh select the row which you want to delete right so what I'm going to do is
25:09
here this is one select the J table right click event action
25:14
uh here this one mouse mouse click right this event we have to write the code mouse mouse
25:20
click here we have to write the code here is simple code I just I already written this one instead of writing
25:27
again by control copy We paste here here this one we have to create the
25:34
model class this is a table model i have created the D default this one we have to create the model right model we have
25:41
to D we have to create the object D here we have write we have to create selected index J table get selected row get
25:48
selected row mean this get selected row j table one mean this J table one we are get selected mean this each and every
25:54
column you'll be able to select right so here first you have to create the variable id first you have selected zero
26:01
index mean this is a 0 1 this is a 1 2 3 4 this how it j table works right uh if
26:07
you select this one this particular ID should be ID right zero push right after
26:13
that we have to write second one should be the we have to assign the relevant text box for edit record txt name this
26:19
one ctrl C to copy ctrl V to paste here second one should be there phone ctrl C
26:26
to copy ctrl + V to paste here third one should be the address ctrl C to
26:32
copy ctrl V to paste here third one should be the age ctrl C to copy control V to paste right so this is
26:40
selected index H right this is thing we have to do uh this is very simple stuff
26:46
we have to do the things why what is the error here
26:55
variable
27:02
D can't find variable selected
27:08
index we have written what's the problem the problem is yeah I have
27:14
written the wrong perfect right now you can check here what happen is this this
27:20
add record when you going to add the records you have disable this button button one so this one should be button
27:27

27:41
edit or delete the record now first I'm going to select the record before you edit or delete the record first I uh
27:47
selected successfully now we will be able to write the code for edit record so election action perform be able to
27:53
write the code for edit track so let's copy the complete record this complete
27:59
record we copy paste here now here we have this
28:07

get the ID so ID mean you have get this ID string ID this one you have get the
28:20
ID and edit when you select this record out edit the record and delete the record the ID we need the ID of this
28:28
uh student right because ID should be the primary key so get the ID and editor
28:33
in the record so this is ID but ID is here it is passing to the variable this
28:39
it's all on the variable ID we have to get it here so we have to write ID here right it's not a uh this one we have to
28:48
this one also we needed selected index this control C copy this all the stuff we needed right selected index right
28:55
only only only for ID right okay we have write this code we have to copy we have

40:44
uh this row will be created so we have to select and remove each and every rows
40:50
right select there will be the button called delete click delete select delete
40:56
it right you have to do right okay this is the design of the
41:03

41:09
every text field right so click on this
41:14
text field right click edit text backspace to remove the existing text select again properties
41:24
uh select Right click change variable name we have to select uh we have to
41:29
give here as txt course name C
41:35

42:26
click event action action perform right now what I'm going to do
42:32
see I have already written all the codes in my previous student on Java here
42:39
right so let's back to my student on Java page first I'm going to establish
42:44
the database connection so what I'm going to do is here uh these are the codes uh I I wrote to establish the
42:52
database connection so So let's let's copy this
43:00
one and here we have to control V to paste here right now
43:06
what I'm going to do is here uh this is the method so
43:12
let's this is a connection method when the form is uh loading this connection method will be
43:19
loaded right so let's control C copy this connection method paste inside the constructor right this is the things we
43:26
have to do first right after that what I'm going to have to register the course right so click on the double click on
43:32
the edit button add button so we have write here uh student on
43:38
Java so this is the code we are written for the add button right this is the button so let's copy that code right C
43:46
to copy control V to paste inside the cob button okay we don't need to write again by again uh once you written you
43:54
just copy and paste and you have to uh change it right now here first what I'm
44:00
going to say this is the variables we are created uh so we have to change the variable name this is this variable cost
44:05
name price and duration so we have to uh change this one as a string course
44:11
name second one should be the
44:16
price third one should be the duration Right first one
44:23
txt this one should be the txt C name mean post
44:28
name second one should be the txt
44:35
price third one should be the txt
44:41
duration right this one we don't needed we just
44:46
remove that right here this is a prepare statement we have written so the prepare statement which table you are going to
44:53
insert the record cost table so insert into which table you are going to insert the record cost table so you have to
45:00
give the table name properly here over here now we have to specify the column
45:06
names within this bracket right so this is the table consist of the uh cost
45:14
table right this is the columns consist of the cost table so ID is auto increment we don't need that uh we we
45:22
need host name price and duration so we have to give here as host
45:27
name comma price duration we have write
45:35
duration right that's the thing we have to do now we have to write the prepare statement right we we have only three
45:42
columns so we have to put three question mark over here now these are the values
45:47
right what are the uh user enter on this text boxes these values are assigning to
45:52
the this variables course name price and duration we have to call it here so Ctrl
45:58
C copy control V paste here right now what I'm going to do is
46:04
here this sequence of parameters follow followed by the sequence of columns in
46:11
the database table right so here what I'm going to do is right now here first
46:18
what I'm going to see we have to after add the uh record uh we have to display the message recorded at uh after that we
46:26
have to clear the each and every text boxes right so what I'm going to see this textbox name control copy control
46:32
bit paste here control copy control bit paste here control copy control bit paste right we have to remove them this
46:39
one control se paste here right now what I'm going to do is say we have to this the post right registration path now
46:46
let's check whether it's working fine or not so let's select this one right click
46:51

48:06
register the course name as Java price I'm going to enter as
48:11

here we have to mark the answer so it's control C to copy ctrl V to paste this have to answer this is the thing we have
1:00:07
to do first right this is essential stuff we have to do after that we have to add the button so here first I'm
1:00:14
going to add the button as add button so here we have to drag the button this
1:00:20
one right this one should be there right you have to add the button right i only
1:00:25
I explain only the add part edit part all the stuff you have to do yourself
1:00:30
right so here here we you can add the questions right so here what I'm going to do is here first uh question number
1:00:37
will be autogenerated right this number I'm going to generate so autogenerated number I gave uh this one go to
1:00:45
structure right now here what I did is here I have this number uh uh I just
1:00:52
remove the auto increment part here I just this one drag this one drop here
1:00:58
drop it again i'm going to edit here only I have put it here uh beginning of
1:01:04
the table go this ID i only
1:01:09
keep 11 only keep primary right i'm not
1:01:15
check the auto increment part so because I have set into my code auto increment
1:01:20
part will be I have set into my code right that is very essential stuff here so when you add the question the one by
1:01:26
one the number should be incremented right so that is a good thing so instead of setting this here right so what I did
1:01:33
here is now let's go to the source first i'm going to establish the database connection i already establish a
1:01:38
database connection here right so let's back to my uh course uh final course
1:01:45
right here we already have a connect database connection we just copy them uh connection object prepare so all the
1:01:52
stuff we just control C to copy back to here questions ctrl V to paste
1:01:57
here click okay right it's working perfectly we added the connection success so this connection object C to
1:02:04
copy control V to paste inside the uh constructor right that is the first
1:02:10
time I did after that I have to do the stuff is this auto increment stuff so
1:02:16
how to make this auto increment stuff is uh we have to create the method this is very
1:02:24
essential stuff okay while you creating the method it's very easy public
1:02:31
int get bill okay we have to
1:02:39
write if it is put in we have to this one should be the method we have to
1:02:44
return something Right so that we have this is a return method right if you pass the
1:02:50
uh data type over here you have write int bill number starting should be one right
1:02:57
after you have write statement class
1:03:06
SMT equal connection object this connection object dot
1:03:14
create statement this one you have to make it
1:03:19
as this class you have to make it here we have to add the try catch block right
1:03:27
after that we have to write here is result set RS equal SMT dot execute query here
1:03:38
we have to write select all from select sorry we have to write only
1:03:44
max you have to write id
1:03:51
from which table this question table just c to copy control to paste
1:03:59
here right this is the thing we have to do we have to add this one as result
1:04:06
set after that we Write here RS do
1:04:13
next after that we have write here is bill number bill number equal
1:04:20
RS dot get in one + one because it is incremented
1:04:29
right it's auto uh incremented by one right so you have to I have to comment it here this one
1:04:35
incremented increment by one auto id auto id set right set
1:04:44
auto id set increment by one right we are set like this right this is essential stuff right finally rs dot
1:04:52
close we have to write the close method that's the stuff we have to do uh finally we have to return the stuff so
1:04:59
return which one you have to return bill number this bill number should be the auto agreement but here copyr to paste
1:05:06
Okay now the error go away this meal number we have set it
1:05:11
here which label this label we have to set it
1:05:16
here okay first you have to name this one as a txt
1:05:23
id this one you have to edit text backspace to remove the excess select
1:05:28
again here we have to txt question give you question qu question you have to
1:05:34

1:10:56
answer make it as null Others are not null this only this column we make it as null this is very
1:11:01
important stuff you must do it okay this very essential stuff you follow the stuff null right now let's back to
1:11:10
here now here first we have to we have to specify the column names for the insert part right so this table is
1:11:16
question table we have to store the records question uh what are the columns we have
1:11:22
to specify the column names first these are the columns names right so we have
1:11:29
write question the ID
1:11:37
questions option one comma option
1:11:44
two comma option three comma option
1:11:50
four comma
1:11:55
Answer command given
1:12:04
answer this one you have to write 1 2 3 4 5 6 7 8 so we have write eight
1:12:13
3 4 5 6 7 8
1:12:22
now here we have write first this ID control C to copy control V to paste here question control C to copy V to
1:12:28
paste here this one option control C to copy control V to paste here after that we have write the third the third three
1:12:35
paste it here the fourth one must be control copy control V to paste here
1:12:43
this one control seat copy V to paste here this one should be six control seat
1:12:49
copy to paste here this one should be control seat copy control V pasty this is seventh one control seat copy control
1:12:54
paste seven right but how many columns available here uh this one not given answer we no
1:13:03
need only seven right question marks are there this is the only stuff we have to
1:13:09
do after that we have to add that according to the database right we have to clear this one right question
1:13:18
added question added right otherwise control copy control question right this
1:13:25
is tough right now let's check whether it's working fine or
1:13:31
not question here uh here first
1:13:37
right what is the variable what is what is variables
1:13:47
variables this is a question right here you have to answer the you have to give the options right uh I just give the uh
1:13:55
option uh
1:14:00
memory memory storage storage temporary so you have to
1:14:07
write like this these are the answer you have to write uh I just put it as a bc second
1:14:14
bc third one should be v bb just like this right the answer
1:14:21
is abc is a correct answer you just write like this okay you have to give the options like this right these are
1:14:26
these how you have options you have the correct answer is this right now if you click add button question added you'll
1:14:32
be able to see the question is added or not can check here it's added successfully question will be added
1:14:38
successfully you'll be able to see Right i hope you guys you understood the things well if you have any doubt on
1:14:44
this you can ask me i will continue the uh tutorial in my next video thank you
1:14:50
for watching hi friends welcome to tutor channel in our last class we discussed
1:14:57
about the questions part how to create the questions in this class I'm going to
1:15:02
make the exam part right here first what I'm going to do is uh in this class I'm
1:15:08
going to show you how to load the questions right how to load the questions right so first what I'm going
1:15:14
to do is here first I'm going to go to the source first I'm going to establish a
1:15:20
database connection first right so let's go to the student java this class source
1:15:28
we have to copy this one connection C to copy
1:15:34
Back to test on Java ctrl + V to paste here right this is the we are this one
1:15:40
here we have to copy this one we this one result set all the stuff we needed
1:15:45
ctrl C to copy control to paste here right now the error is go away right perfect after that what I'm going to do
1:15:52
is here I'm going to make write the call right here right here okay the connection i'm going to write the query
1:15:58
after that uh when the connection is established we have to load the
1:16:04
uh we have to separate we have to put it the this one load the question right we have
1:16:09
to we have to create the method load questions right so we have to write separate we have to write public
1:16:18
uh wide load questions load
1:16:23
questions questions method Right okay so perfect now here what I'm
1:16:30
going to do is here first we have to write the query string
1:16:36
uh query we have to write query equal
1:16:42
select all from questions we have to lo the questions
1:16:48
right so we have to write the after that you have to write the statement class right therefore we have to write
1:16:53
statement class statement statement st equal null we
1:17:00
have to write statement class equal null right we have to create create the object of statement class right
1:17:06
establish the name space right after that what I'm going to do is here we have write
1:17:12
here statement object equal connection dot
1:17:19
create back statement right now here what I'm going to see you have write the result set object you have to write
1:17:24
result set object you have to create the already RS you have to get the result set object RS here we have this one you
1:17:30
have to add it here try and catch sound try and catch result set object RS
1:17:37
equal stment dot execute
1:17:43
query here we have write this we have to paste it here after that we have write loop
1:17:53
while RS dot next here we have to write inside the
1:18:00
while loop we have to write first we have to write the text boxes name first we have to
1:18:07
uh load the uh question ID here this is a question ID J label 3 J label 3 dot set
1:18:20
text set text set text write set text here we have to
1:18:26
write RS dot Get string first one mean what is the column
1:18:34
ID right after that the same thing control C to copy Ctrl C to paste here second one should be
1:18:41
the second one should be the question number right this this one should be J label two this this label two this is
1:18:49
two two mean RS2 mean understand question right uh database column will
1:18:56
be starting position of zero 1 2 3 4 5 6 7 right so this is the position of two
1:19:03
right understand the concept right same thing control C to copy control V to paste here now here what I'm going to do
1:19:09
is here uh this one should be the radio button so we have to change the name
1:19:15
here right this one R1 this one R2 simply we have to
1:19:22
R2 rather than writing the full full one we have to change it as it is simply we have to write R4 R4 right that's the
1:19:31
stuff you have to write okay so you have to write that one this one should be R1
1:19:38
uh radio button right R1 dot set text RS the same thing this one should be the
1:19:44
three three mean option one right we have to fill off these ones
1:19:51
so here same thing C to copyr to paste here R2
1:20:00
R2 4 control C copy control V to paste the
1:20:08
R3
1:20:13
5 R six uh R4
1:20:19
six right six correct answer we have to create one variable for here i'm going
1:20:27
to create the variable above correct answer right see how to
1:20:39
correct equal this one ctrl C to copy control V
1:20:45
to paste here equal RS get
1:20:52
string 7 right this is the thing we have to do
1:20:58
right first after that here only we have only one row there are many questions
1:21:04
are available first question only will be loaded right so here we have to write for I'm going to comment it for one
1:21:14
row only this is very important stuff while you're loading the questions right
1:21:20
here after that break it is break it is not loading the remaining also only the one row we have to load so only one row
1:21:26
this only one row right if there are some plenty of questions available it's ignore them only the load first question
1:21:33
only right so that's the stuff we have to do this load question we have to control
1:21:40
Copy have to paste it here the same thing the connection as
1:21:45
well C to copy control V to paste here now let's run and check whether it's working fine or not questions right
1:21:51
click
1:21:58
Not not question it's a test no I forgot right it's not question test right click
1:22:06
test why is not wrong connection online exam does not exit
1:22:14
what is a problem
1:22:27
right here the problem is the questions this is not a questions question this is
1:22:33
a questions uh that's the problem I think now let's again run
1:22:40
it yeah here it's working perfect it's working this is the first question this
1:22:46
is the first here this one should be the here this is right okay this is the stuff we have to load the
1:22:53
uh form right very simple stuff uh you must try this one right uh we will be uh
1:23:00
do do the rest of part in my next tutorial thank you for watching hi friends welcome to tutors
1:23:08
funny channel today I'm going to teach the part six tutorial of online uh exam
1:23:13
system here in this video I had already written all the codes because if I return from the beginning it take too
1:23:20
much of time to complete the video so you all I hope you all are boring uh so
1:23:26
that I have to responsibly teach all the lessons so that I have to I thought that
1:23:32
I already done the code don't worry about that i'll be explained uh from the scratch right so
1:23:38
here what first what I'm going to is we have to this each and every uh label uh
1:23:44
radio button here I already change this one R4 this question this all the radio
1:23:50
button we have to change it as a radio group right that's important stuff so what how to change this one as one radio
1:23:56
group there will be the option called uh under the sewing control radio group
1:24:01
button group you just drag and drop okay if you just drag and drop here you can get the option button group right so we
1:24:08
have to set each and every button for the group right so click on the first
1:24:13
radio button you have to check on this one you have radio button group you have to check the one second one select this
1:24:19
one you have to check it as one third one check it as one fourth one check it
1:24:25
as one this how we have check it right now what I'm going to do is here after check all the stuff uh now let's run the
1:24:33
application check this is a test right some error uh what's the
1:24:44
problem okay okay here the [Music]
1:24:54
problem it's already there statement
1:25:02
class statement class we have to statement class statement class here
1:25:10
[Music] write
1:25:25
states right there I go away now right there I go away now what's the problem
1:25:31
all right this is a label one number field copy paste button okay
1:25:39
perfect but I go now let's try and
1:25:46
check right so only question available that's why it's it's not going uh now
1:25:52
here what I'm going to I'm going to add another questions so here go to the student question this one but add
1:25:58
another question i just add the question as something like that uh what
1:26:06
is JDBC what is JDBC you just answer some
1:26:11
option right a B I just answer that you have to uh able to add the question
1:26:18
right here okay answers okay i just A is the correct answer so click right question entered now let's check here go
1:26:25
to the test yeah right now here we have to mark it this one here it's working
1:26:32
perfectly it's working well it's working right here it's working what's the problem here online question table is not exit
1:26:41
square line exam questions so tables so
1:26:46
here the problem is coming here questions tables questions tables
1:26:55
questions given answer this is tables question for
1:27:02
question question the table name is question that's a problem right we have write
1:27:09
select all the answer question that's a problem we ask a
1:27:16
question
1:27:27
Right now let's check it's working perfectly well okay
1:27:34
right now it's working well right now here now why what I'm going to do is here right here it's working here right
1:27:42
now here first what I'm going to do is here here if you click on this one if
1:27:48
the answer is correct the mark should be mark it as one if it is if your answer is correct mark it as if you click here
1:27:54
uh the answer doesn't correct dot marks is increased if your answer is correct here it will be increase the marks right
1:28:00
here okay it is increase the mark marks right here okay now here first what I'm going to do is how to make this system
1:28:06
so first what I'm going to see I already I show in my last tutorial how to load this questions right when the form is
1:28:12
loaded all the question will be loaded after that what I did is
1:28:17
here in my last tutorial we discussed about this one right connection method this is a load question we already we
1:28:24
load all the questions right after that what I did is here after that I have created
1:28:29
the boolean method which is a check answer just a method right now we have
1:28:35
declared this variables right this is a correct answer co r string answer uh
1:28:41
variable statement class right after that what I did here This we have to create inside this method we have to
1:28:46
create the variable answer uh answer uh answer answer this one R1 dot selected
1:28:53
mean if the this should be radio button name as R1 if it is selected answer this
1:29:00
answer equal R1 dot what is the answer you are selected here it is assigned to this variable if the user select the
1:29:07
radio button two it assigned to this variable if the radio button three selected shall assign to this variable
1:29:12
four etc this one right You have to selected like this right uh after that we have to select here if the answer
1:29:18
equal dot correct answer if it is if you select the correct answer you are mean
1:29:24
here I mark it here correct answer mean
1:29:32
here here like this okay is the correct answer this is the correct okay here the correct answer we have to make this one
1:29:38
C R right we create the variable C here right this one we know here correct answer we have to already create C here
1:29:46
right this one right so here when the form is loaded the correct answer already you are loaded right we have to
1:29:53
uh discuss this stuff in my last tutorial so this is the correct answer so we have to check here from here right
1:30:01
get the correct answer right uh if it is is assigned to the relevant variables you have to check answers answer this
1:30:08
variable answer dot equal into correct answer if it is correct and answer equal
1:30:14
null if it is null or if it is not equal to this one what happen is we have to
1:30:21
put it here marks we have to already create the variable marks one it is increment by one right it is assigned to
1:30:27
the uh this one this label right label so that we have to do the set text string to mark right else if we have to
1:30:34
write uh if it is not equal to this one or null we have to create this one if it
1:30:39
is minus right if it is minus right if uh the purpose this one is why this one deducted only deduct if the marks
1:30:46
greater than zero the thing is uh uh student uh sometime
1:30:53
uh first at the first attemp they will be mark it as correct answer after that
1:30:59
they they uh wish to change the answer as wrong answer that that kind of
1:31:05
situation we have to reduce the marks so that we have okay okay that is the
1:31:11
purpose we have right sometime they have selected the correct question so that marks could be one uh sometime
1:31:18
they uh they wish to change the answer that the marks would be reduced that that that's how we reduce that stuff
1:31:24
okay that's why we have to we have to here we have to uh write it here only deduct if the mark's greater than zero
1:31:31
right so we have assigned to the labels after that we have to write if greater than not equal
1:31:36
here we have to write string uh uh we have to update the given answer we ask a question here given answer we have to
1:31:42
update it right so here we have to give an answer we have to write okay this one here the given answer should be added
1:31:49
right here it should be added okay now here here like this okay if you run the
1:31:55
system you can see here if you are what is the answer you are you marking click next you'll be able to see here when you
1:32:03
load the system here you should be mark it 1B likewise right it is shattered successfully here
1:32:09
okay that's how it's working the system right if you mark it here as D click
1:32:15
next here you can check here the the your selected answer should be added D
1:32:21
right likewise it is checking the given answer and this answer okay that's how we have to uh do the program like this
1:32:28
okay so this one here this is the thing we have It's updating right set given answer what is the answer you are given
1:32:34
via question number right it is here this one should be updating right that's the thing we have to do here right after
1:32:41
written for this simple one we have to do it here this simple program we are do it uh no problem I will attach this code
1:32:47
in my uh video description so you have to you you'll already you'll be able to
1:32:53
try the course right so it's simple to have a programming right so after that a
1:32:58
null here null N given answer if it is null you have to clear one right here this one all from a prepared statement
1:33:06
this question number what is the question number here it is clear right null given answer right this one we have
1:33:11
to call it here lot the
1:33:17
question call it
1:33:22
here right this is a right this is a button
1:33:27
so already answered right here this already answered if it's not already answered here already answer the already
1:33:33
answer function does this one select query given answer from given
1:33:40
answer mean this given answer we have to check this column from the question
1:33:45
table where the question label what is the question here it will be this what
1:33:51
is the answer is mask here it is loaded so the already answer if it is answer already answer it is loaded here it is
1:33:57
all you have calculate the already answer so here we have to make the next button we have to do the next button
1:34:03
here we have to write if rs does next second question is go correct answer if
1:34:08
it's already answered it will be uh button we have to enable all the clear
1:34:14
all the buttons proceed okay do radio button group clear section mean all clear all buttons right if this all the
1:34:21
questions are entered you have to show the first question right this is the things we have right very simple one uh
1:34:28
you no you don't worry about that this is very difficult to explain this uh code step by step I will attach my video
1:34:35
description you will be able to I will explain it uh you'll be able to download and you have study it's very difficult
1:34:42
course right okay it's explain okay it take too much of time to explain so it's
1:34:47
so boring here a simple course you have to write very simple course some already answers those all
1:34:53
the stuff right here okay I hope you guys understood so far thank you for
