    JButton button;                                  // Stores a button
    for(int i = 1; i <= 6; i++)
    {

      button.addActionListener(this);                // Add listener for button

  }

  // Handle button events
  public void actionPerformed(ActionEvent e) 
  {
      card.next(getContentPane());                  // Switch to the next card
  }
