程序1用Button组件实现，程序2用JButton组件实现。
--------------------程序1开始--------------------
Music.java

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

public class Music extends Applet {
Button play,loop,stop;
AudioClip audio = null;

public void init() {
 resize(200,30);
 play = new Button("play");
 loop = new Button("Loop");
 stop = new Button("Stop");
 stop.disable();
 add(play);
 add(loop);
 add(stop);
 audio = getAudioClip(getCodeBase(),"mid/fy.mid");  
}

public boolean action(Event event,Object arg) {
 if(event.target == play) {
   if(audio!=null) {
     audio.play();
     play.disable();
     loop.disable();
     stop.enable();
     showStatus("playing sound only once!");
   }else
     showStatus("Sound file no loaded");
     return true;
 }else if(event.target == loop) {
   if(audio!=null) {
     audio.loop();
     play.disable();
     loop.disable();
     stop.enable();
     showStatus("Playing sound all the time!");
   }else
     showStatus("Sound file not loaded");
     return true;
 }else if(event.target == stop) {
   audio.stop();
   loop.enable();
   stop.disable();
   showStatus("Stop playing sound!");
   return true;
 }
 return false;
}
}

-----------------程序2开始------------------

 add(play);
 play.addActionListener(
   new ActionListener() {
     public void actionPerformed(ActionEvent event) {
       playActionPerformed(event);
     }
   }
 );
