Event Adapters
• The listener classes that you define can extend adapter
classes and override only the methods that you need.
• An example is:
1 import java.awt.*;
2 import java.awt.event.*;

7 // an adapter to avoid having to write all the
8 // event handler methods

10 public void mouseClicked(MouseEvent e) {
11 // Do stuff with the mouse click...
