使用java applet实现播放音乐

音乐文件的格式一定是wav,au之类的，不支持mp3.

import java.applet.*;

import java.awt.*;
import java.awt.event.*;
public class AudioChoiceTest extends Applet implements ActionListener{
public final String[] AUDIO={"青花瓷","菊花台","红尘客栈"};

{

choice=new Choice();
clips=new AudioClip[AUDIO.length];
clipsPlaying=new boolean[AUDIO.length];
for(int i=0;i<AUDIO.length;i++)
{
choice.add(AUDIO[i]);
clips[i]=getAudioClip(getCodeBase(),AUDIO[i]+".wav");
clipsPlaying[i]=false;
}
add(choice);
playClip=new Button("播放");
playClip.addActionListener(this);
add(playClip);

loopClip=new Button("循环");
loopClip.addActionListener(this);
add(loopClip);
