Anything wrong here?
JButton btnCheckout = new JButton("Checkout");
btnCheckout.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
racingUsr.setVisible(false);
int row = 0;
int col = 4;
int price = 0,subtotal = 0,qty = 0,rowin = table.getSelectedRow();
if(rowin == 0){
qty = Integer.parseInt(JOptionPane.showInputDialog(null,"How many of that game?"));
Object a = table.getModel().getValueAt(row, col);
a = price;
subtotal = price * qty;
JOptionPane.showMessageDialog(null, subtotal);
}
}
});
Table has 5 rows and 1 column (currently, cant add more yet with this error) coming in from the SQL database. When i enter '5' in the quantity, it outputs '0' in the subtotal. And i also need an extra help for the quantity count, when i buy a game, of course the quantity should decrease but how? I hope someone can help. TIA.
Error:
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 1 >= 1
You have a=price; instead of price = a;
This is the reason because you get the 0 in the subtotal.
