正在做java作业，想要在拼图游戏里加上一个背景音乐，怎么破，明天就要交了，求大神解救

import java.applet.Applet;

import java.applet.AudioClip;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.net.URI;
import java.net.URL;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class f extends JFrame implements ActionListener {
private static final String AudioClip = null;
private JButton Oj;
private JButton Oj1;
AudioClip clip =null;
File musicFile;
URI uri;
URL url;
private void f() throws InterruptedException{
musicFile = new File("/zxc.wav");
uri = musicFile.toURI();
try {
url = uri.toURL();
} catch (Exception e) {
}
clip=Applet.newAudioClip(url);
//clip.play();
}
f() {
this.setSize(800, 600);
this.setResizable(false);
JPanel p = new JPanel();
this.setContentPane(p);
this.setVisible(true);
Oj = new JButton("开始");
Oj1 = new JButton("结束");

this.setVisible(true);
Oj.addActionListener(this);
Oj1.addActionListener(this);
this.add(Oj);
this.add(Oj1);
}
public static void main(String[] args) throws InterruptedException {
f ff=new f();
ff.f();
}
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
if (e.getSource() == Oj) {

play();
} else if (e.getSource() == Oj1) {

stop();
//System.exit(0);
}
}
public void play() {
if (clip != null)
( (java.applet.AudioClip) clip).play();
}
public void stop() {
if (clip != null)
( (java.applet.AudioClip) clip).stop();
}
}这是在网上查到的代码，加到程序里一直错，该怎么改改插进去

java.net.URL musicPath=MyActionListener.class.getResource("音乐目录");
    music= java.applet.Applet.newAudioClip(musicPath);
       music.loop();//循环播放不行找我
