public void play(String Filename)
{
try{
// 用输入流打开一音频文件
InputStream in = new FileInputStream(Filename);//FIlename 是你加载的声音文件如(“game.wav”)
// 从输入流中创建一个AudioStream对象
AudioStream as = new AudioStream(in);
AudioPlayer.player.start(as);//用静态成员player.start播放音乐
//AudioPlayer.player.stop(as);//关闭音乐播放
//如果要实现循环播放,则用下面的三句取代上面的“AudioPlayer.player.start(as);”这句
/*AudioData data = as.getData();
ContinuousAudioDataStream gg= new ContinuousAudioDataStream (data);
AudioPlayer.player.start(gg);// Play audio.
*/
//如果要用一个 URL 做为声音流的源(source),则用下面的代码所示替换输入流来创建声音流:
/*AudioStream as = new AudioStream (url.openStream());
*/
} catch(FileNotFoundException e){
System.out.print("FileNotFoundException ");
} catch(IOException e){
System.out.print("有错误!");
}
}
使用play()方法进行播放,loop()方法循环播放,stop()方法停止播放。
实际例子:
File file1 = new File("src\\music\\11.wav");
AudioClip sound1;
sound1 = Applet.newAudioClip(file1.toURL());
sound1.play();
这样就实现了播放音乐的功能,注意J2SE默认只支持 wav格式的音频。

你的程序刚执行可能就结束了,声音还没来得及播放。把abs.playa()放在这段代码下面:
try{
playWav abs=new playWav();
abs.playa();
Thread.sleep(5000);//时间跟据你声音文件播放的长短定
}catch(Exception e)
{e.printStackTrace();}
============================================
还是你的代码,我加了主函数的情况:
import java.io.*;
import java.lang.*;
import java.net.*;
import java.applet.*;
public class playWav{
public void playa() {
try{ File f=new File("msg.Wav");
URI uri=f.toURI();
URL url=uri.toURL();
AudioClip msg=Applet.newAudioClip(url);
msg.play();
}
catch (Exception e)
{
}
}
public static void main (String[] args) {
try{
playWav a=new playWav();
a.playa();
Thread.sleep(5000);
}catch(Exception e){e.printStackTrace();}
}
}
