Exercise Nine  
  • Okay, let's make our simple example from last exercise handle events using the 1.1 methodology:


    import java.awt.*;
    import java.awt.event.*;
    public class Event11Example extends Panel
           implements ActionListener
      public Panel     displayPanel;
      public Button    colorButton;
      public Color[]   colors = {Color.black,
      private int	   counter = 0;
      public Event11Example()
        setLayout(new BorderLayout());
        displayPanel = new Panel();
        add("Center", displayPanel);
        colorButton = new Button("Change Color");
        add("South", colorButton);
      public static void main(String[] args)
        Frame baseFrame = new Frame();
        Event11Example ee = new Event11Example();
        baseFrame.add("Center", ee);
        baseFrame.setTitle("Event Example");
      public void actionPerformed(ActionEvent evt)
        if (counter <=2)
           counter =0;
