The Restaurant Simple Pos is developed using Java. The project is built to manage sales and transactions. To make a new transaction, fields such as: Item type with ingredients, qty needs to be selected. If you like to learn point of sales systems step by step, this is the right place to learn from the beginning. In this tutorial useful for making a point of sales system for a small shops.
The system shall be able to select the relevant Item type with Ingredients type.
Creating variable
String item; String ind; int i = 0;
Paste the code inside the addbutton
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
if(txtqty.getText().isEmpty())
{
JOptionPane.showMessageDialog(this, "Please Enter the Qty");
}
else
{
if(lblroll.isSelected() == true )
{
item = "Roll";
if(lblveg.isSelected() == true)
{
i = 12;
ind = lblveg.getText();
}
else if(lblfish.isSelected() == true)
{
i = 20;
ind = lblfish.getText();
}
else if(lblchicken.isSelected() == true)
{
i = 25;
ind = lblchicken.getText();
}
}
else if(lblbun.isSelected() == true )
{
item = "Bun";
if(lblveg.isSelected() == true)
{
i = 20;
ind = "Veg";
}
else if(lblfish.isSelected() == true)
{
i = 25;
ind = "Fish";
}
else if(lblchicken.isSelected() == true)
{
i = 28;
ind = "Chicken";
}
}
else if(lblpasty.isSelected() == true )
{
item = "Pasty";
if(lblveg.isSelected() == true)
{
i = 30;
ind = "Veg";
}
else if(lblfish.isSelected() == true)
{
i = 35;
ind = "Fish";
}
else if(lblchicken.isSelected() == true)
{
i = 38;
ind = "Chicken";
}
}
int qty = Integer.parseInt(txtqty.getText());
int tot = qty * i;
txttotal.setText(String.valueOf(tot));
model = (DefaultTableModel)jTable1.getModel();
model.addRow(new Object[]
{
item + " " + ind,
i,
txtqty.getText(),
txttotal.getText(),
});
int sum=0;
for(int a=0; a<jTable1.getRowCount(); a++)
{
sum = sum + Integer.parseInt(jTable1.getValueAt(a, 3).toString());
}
jLabel4.setText(Integer.toString(sum));
lblroll.setSelected(false);
lblbun.setSelected(false);
lblpasty.setSelected(false);
lblveg.setSelected(false);
lblfish.setSelected(false);
lblpasty.setSelected(false);
txtqty.setText("");
txttotal.setText("");
}
}if you want remove items from the jtable. select the row of table which item wants to. then click delete button
Delete Button
Paste the code inside the addbutton
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
model.removeRow(jTable1.getSelectedRow());
int sum=0;
for(int a=0; a<jTable1.getRowCount(); a++)
{
sum = sum + Integer.parseInt(jTable1.getValueAt(a, 3).toString());
}
jLabel4.setText(Integer.toString(sum));
}I have attached the video tutorial below it will help you to do this step by step.
