首先要在环境电脑中安装下JMF环境，才能引入javax.sound.sampled.*这个包，一下是用过的代码

package TheMusic;
import java.io.*;
import javax.sound.sampled.*;
public class Music {
public static void main(String[] args) {
// TODO Auto-generated method stub
//修改你的音乐文件路径就OK了
AePlayWave apw=new AePlayWave("突然好想你.wav");
apw.start();
}
}
在程序中实例化这个类，启动线程，实例化的时候参照Test修改路径就OK播放声音的类
Java代码
public class AePlayWave extends Thread {
private String filename;
public AePlayWave(String wavfile) {
filename = wavfile;
}
public void run() {
File soundFile = new File(filename);
AudioInputStream audioInputStream = null;
try {
audioInputStream = AudioSystem.getAudioInputStream(soundFile);

return;

DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);

auline.open(format);

byte[] abData = new byte[512];

Applet我没有学过-------现在都用Swing了，AWT都很少用的。
我跑了下你的程序，你的错误在这：
sound=getAudioClip(getDocumentBase(),"test.mp3");
也就是AudioClip 对象没有创建成功！
在监听器中触发事件的时候，你首先要判断AudioClip 不为空，然后才能进行播放！
if (obj == plays) {
if (sound != null) {
sound.play();
} else {
sound = getAudioClip(getDocumentBase(), "D:\\lalala.wma");
sound.play();
}
} else if (obj == stops) {
。。。。。
这样写是对的写法
但是sound = getAudioClip(getDocumentBase(), "D:\\lalala.wma");
还是没有构建成功。所以，你构建AudioClip估计是错误的写法。
Appletde API太老了，我没有看，所以给你个Swing写的代码，你跑下看看，编译通过的。建议你不要用Applet了！
