Add action to a JButton created by another JButton

Question

I have a Jbutton that when pressed creates another button and the new button is added to the panel. How to I add an actionListener to the new button?

For example:

Answer 1

For each button you can create it's own actionPerformed(...) method, as described in the example below : Do you mean to do this :

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class ButtonAction
{
    private JPanel contentPane;
    private JButton updateButton;
    private int count = 0;
    private ActionListener updateListener = new ActionListener()
    {
        public void actionPerformed(ActionEvent ae)
        {
            final JButton button = new JButton("" +  count); 
            button.setActionCommand("" + count);
            button.addActionListener(new ActionListener()
            {
                public void actionPerformed(ActionEvent event)
                {
                    System.out.println("My COMMAND is : " + event.getActionCommand());
                }
            });
            SwingUtilities.invokeLater(new Runnable()
            {
                public void run()
                {
                    contentPane.add(button);
                    contentPane.revalidate();
                    contentPane.repaint();
                }
            });
            count++;
        }
    };

    private void createAndDisplayGUI()
    {
        JFrame frame = new JFrame("BUTTON ACTIONS");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationByPlatform(true);

        contentPane = new JPanel();
        contentPane.setLayout(new FlowLayout(FlowLayout.LEFT, 5, 5));

        updateButton = new JButton("UPDATE GUI");
        updateButton.addActionListener(updateListener);

        frame.add(contentPane, BorderLayout.CENTER);
        frame.add(updateButton, BorderLayout.PAGE_END);

        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String... args)
    {
        Runnable runnable = new Runnable()
        {
            public void run()
            {
                new ButtonAction().createAndDisplayGUI();
            }
        };
        SwingUtilities.invokeLater(runnable);
    }
}
