小弟求救!弄了一个上午,也不知是咋回事.

import java.awt.*;
import java.applet.*;
import java.awt.event.*;

public class aaa extends Applet implements WindowListener/*,ActionListener*/
{

public aaa()
{
super();
Panel p=new Panel();
Button b1=new Button();
Button b2=new Button();
Button b3=new Button();
TextField t=new TextField(10);
b1.setLabel("1");
b2.setLabel("2");
b3.setLabel("+");
/*b1.addActionListener(this);???????为什么不让俺注册呢!!!
b2.addActionListener(this);
b3.addActionListener(this);*/

p.add(b1);
p.add(b2);
p.add(b3);
addPhone;
addCamera;

p.setVisible(true);
}
public void windowClosing(WindowEvent aaa){System.exit(1);}
public void windowOpened(WindowEvent e){}
public void windowIconified(WindowEvent e){}
public void windowDeiconified(WindowEvent e){}
public void windowClosed(WindowEvent e){}
public void windowActivated(WindowEvent e){}
public void windowDeactivated(WindowEvent e){}

/*public void actionPerformed(ActionEvent e, Object O)
{
String s;
int n;
s=e.getActionCommand();

*/
请问e.getsource怎么用呀??
   谢谢各位大侠.小弟已经抓狂了!!!!
  G:\java\11\aaa.java:6: aaa is not abstract and does not override abstract method     actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener
  public class aaa extends Applet implements WindowListener,ActionListener
