How would code#2 be modified so that the setActionCommand to arraylist and removed
again work in that code. I will have several panels filled this way with checkboxs and I need all of the setActionCommands going to the same arraylist. Because there is a order being created by this.

import java.awt.Color;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.List;

import javax.swing.*;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class ActionCommandTest extends JFrame implements ActionListener
{
     private List actionCommandList = new ArrayList();

     public ActionCommandTest()
     {
          super();

          initialize();
     }

     private void initialize()
     {
          JPanel panel = (JPanel) getContentPane();

          panel.setLayout(new GridLayout(4, 4));

          for (int i = 0; i < 12; i++)
          {
               JButton button = new JButton("Hello - " + i);
               button.setActionCommand("./test/muruga/wavefile-" + i + ".wav");
               button.addActionListener(this);

               panel.add(button);
          }

          setSize(400, 400);
          setVisible(true);

          setDefaultCloseOperation(EXIT_ON_CLOSE);
     }

     public void actionPerformed(ActionEvent e)
     {
          String actionCommand = e.getActionCommand();

          if (actionCommandList.contains(actionCommand))
          {
               ((AbstractButton)e.getSource()).setForeground(Color.black);
               actionCommandList.remove(actionCommand);
          }
          else
          {
               ((AbstractButton)e.getSource()).setForeground(Color.blue);
               actionCommandList.add(actionCommand);
          }

          System.out.println("Action command list is: " + actionCommandList);
     }

     public static void main(String[] args)
     {
          new ActionCommandTest();
     }
}
