java 如何播放wav ？

[LoginOut]

public class AudioPlay {
	URL radio = null;

	AudioClip clip = null;

	File file = null;

	public static void main(String[] args) throws MalformedURLException {
		new AudioPlay().play("D:\\Emergency.wav");
	}

	public void play(String path) throws MalformedURLException {
		file = new File(path);
		radio = file.toURL();
		clip = Applet.newAudioClip(radio);
		clip.play();
	}

}

运行完后，没有反应，也就是说没有声音，
但是Emergency.wav 用其他的播放软件能出来声音

这是怎么回事啊？

刚刚在看，就随便Copy过来了 ，使可以play的

给你三个播放的方法，分为三个类，建议采用第二或第三个：

 
package org.bling.music; 

import java.io.File; 
import java.io.FileInputStream; 
import java.io.IOException; 
import java.io.InputStream; 


import sun.audio.AudioPlayer; 



public class MusicTest2 { 

private InputStream inputStream = null; 
private String file = "./intel.wav"; 

public MusicTest2(){ 
} 

public void play() throws IOException{ 
inputStream = new FileInputStream(new File(file)); 
AudioPlayer.player.start(inputStream); 
} 

public static void main(String[] args) { 
try { 
new MusicTest2().play(); 
} catch (IOException e) { 
e.printStackTrace(); 
} 

} 

}

} 
audioInputStream.close(); 
sourceDataLine.drain(); 
sourceDataLine.close();

测试的是第二个，可行

可以说说我的代码为什么不行吗？
