Adapter Classes and Actions in Event Driven Programming
Java adapter classes provide the default implementation of listener interfaces. If you inherit the adapter class, you will not be forced to provide the implementation of all the methods of listener interfaces. So it saves code.
The adapter classes are found in java.awt.event, java.awt.dnd and javax.swing.event packages. The Adapter classes with their corresponding listener interfaces are given below.
java.awt.event Adapter classes
| Adapter class | Listener interface |
|---|---|
| WindowAdapter | WindowListener |
| KeyAdapter | KeyListener |
| MouseAdapter | MouseListener |
| MouseMotionAdapter | MouseMotionListener |
| FocusAdapter | FocusListener |
| ComponentAdapter | ComponentListener |
| ContainerAdapter | ContainerListener |
| HierarchyBoundsAdapter | HierarchyBoundsListener |
java.awt.dnd Adapter classes
| Adapter class | Listener interface |
|---|---|
| DragSourceAdapter | DragSourceListener |
| DragTargetAdapter | DragTargetListener |
javax.swing.event Adapter classes
| Adapter class | Listener interface |
|---|---|
| MouseInputAdapter | MouseInputListener |
| InternalFrameAdapter | InternalFrameListener |
Java WindowAdapter Example
- import java.awt.*;
- import java.awt.event.*;
- public class AdapterExample{
-     Frame f;
- Â Â Â Â AdapterExample(){
-         f=new Frame(“Window Adapter”);
-         f.addWindowListener(new WindowAdapter(){
-             public void windowClosing(WindowEvent e) {
- Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â f.dispose();
- Â Â Â Â Â Â Â Â Â Â Â Â }
- Â Â Â Â Â Â Â Â });
- Â Â Â Â Â Â Â Â f.setSize(400,400);
- Â Â Â Â Â Â Â Â f.setLayout(null);
- Â Â Â Â Â Â Â Â f.setVisible(true);
- Â Â Â Â }
- public static void main(String[] args) {
-     new AdapterExample();
- }
- }
