Add ActionListener to JButton

Question

Hi, i am creating some buttons to be added to a grid layouy content pane. The buttons are added like this:
for (int i = 0; i < 400; i++)
gamePanel.add(new JButton("" + i));
How do i add an action listener to each button?

Answer 1

I don't really understand what your problem is but here goesJPanel gamePanel = new JPanel(new GridLayout(400, 1));
ActionListener actionListener = new ActionListener() {
     public void actionPerformed(ActionEvent e) {
          Object source = e.getSource();
          if (source instanceof JButton) {
               System.out.println("button " + ((JButton)source).getText() + " clicked");
for (int i = 0; i < 400; i++) {
     JButton button = new JButton("" + i);
     button.addActionListener(actionListener);
     gamePanel.add(button);
}
