关于java播放wav格式音乐问题及代码解释

修改成wav格式的音乐：使用酷狗的转换格式；（java 可以使用的格式之一）

播放音乐的源代码：
第一个
package com.button.One;

import sun.audio.*;
import java.io.*;
import java.applet.*;
import java.net.*;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import sun.audio.AudioPlayer;
public class MusicTest {

private InputStream inputStream = null;private String file = "F:\\Beyond.wav";public MusicTest() {}public void play() throws IOException {    inputStream = new FileInputStream(new File(file));    AudioPlayer.player.start(inputStream);}public static void main(String[] args) {    try {        new MusicTest().play();    } catch (IOException e) {        e.printStackTrace();    }}

}

此时 为完成 软件工程课设
实现第一个
其余两个没有去运行
