Jbutton with double functions....

Question

Hello,
I have a button that does fullscreen and then toggles to minimize one it is in fullscreen. How can i add the minimize operation to it?
The code is as following:
buttonPanel.add(Box.createRigidArea(new Dimension(10, 0)));
          final JButton button1 = new JButton("Fullscreen");
          button1.setAlignmentX(Component.CENTER_ALIGNMENT);
          buttonPanel.add(button1);
          button1.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                         containinFrame.setVisible(false);
                         containinFrame.removeNotify();
                         containinFrame.setUndecorated(true);
//                         frame.pack();
                         containinFrame.setSize(Toolkit.getDefaultToolkit().getScreenSize().width,Toolkit.getDefaultToolkit().getScreenSize().height);
                         containinFrame.setLocation(0, 0);
                         containinFrame.addNotify();
                         containinFrame.setAlwaysOnTop(true);
                         button1.setText("Close");
                         containinFrame.setVisible(true);

since i have to use 2 listenersIs this homework? That sounds like an unnecessary requirement. Why not just use a single ActionListener with a boolean remembering the state of the component, like above?
Nevertheless, a (more complicated) two-listener approach:
JButton toggleButton = new JButton("Maximize");
toggleButton.addActionListener(new MyMaximizeListener());
class MyMaximizeListener implements ActionListener {
   public void actionPerformed(ActionEvent e) {
      // Code to maximize
      JButton source = (JButton)e.getSource();
      source.removeActionListener(this);
      source.setText("Normal Size");
      source.addActionListener(new MyMinimizeListener());
class MyMinimizeListener implements ActionListener {
   public void actionPerformed(ActionEvent e) {
      // Code to restore size to normal
      JButton source = (JButton)e.getSource();
      source.removeActionListener(this);
      source.setText("Maximize");
      source.addActionListener(new MyMaximizeListener();
}
