The AWTEventListener class’ sole purpose is to view events. All you have to do is to implement the eventDispatched method. The following application demonstrates how:

import java.awt.*;import java.awt.event.*;public class EventTest extends Frame {   public EventTest(String title) {      super(title);   }     void init()   {      setSize(100,100);      setVisible(true);      getToolkit().addAWTEventListener(new AWTEventListener() {         public void eventDispatched(AWTEvent e) {            System.out.println(e+"["+e.getID()+"]");         }},         AWTEvent.KEY_EVENT_MASK | AWTEvent.MOUSE_EVENT_MASK |         AWTEvent.MOUSE_MOTION_EVENT_MASK);   }   public static void main (String args[]) {      EventTest et=new EventTest("Monitoring events:");      et.init();   }}

Note: This application can be used for keyboard and mouse events.
