This JDBC will teach you how to do basic database functions that are CREATE RETIEVE in Netbeans. using Mysql Database. The INSERT, SELECT statements can be used in any database system, because this is support by all relational database systems.
We will learn how to INSERT, SELECT in database by writing code to manage the addressbook table in the database named records. records table consist of following columns name,address,age.
First Step
Install Scence Builder in your computer follow this link to download the scene builder which will offers all visual layout components which will easy to drag and drop and make the attractive look. After installed the Scence Builder in your computer successfully.open the netbeans and select new project ->JavaFx- you can select here JavaFx FXML Application and click next it will automatically configure the scene builder path. i attached the
screen shot image below.
After created the project you will get the project structure look like below.
Double click and open the FXMLDocument.fxml your Scence Builder will be loaded and open. then your make your design as you like.
after done the design you must name textfields and tables and tables coloums. after that copy code. go to view->Sample Skeleton
Copy the code
And paste into FXMLDocumentController inside the class. remove the default design and keep as it is a initialize method. this code which will manage the Add Records and View Records from the database.
