java中音频文件的结尾

Question

我写了这个播放音频文件的代码，我想在播放完音频文件后得到提示。我也试过。getMicrosecondLength（）==AS。getMicrosecondPosition（）但是这些方法对于音频流是未定义的。请告诉我怎么做

import java.io.FileInputStream;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;


public class A {

    public static void main(String arg[]) throws Exception {

        AudioStream AS = new AudioStream(new FileInputStream("sounds.wav"));
        AudioPlayer.player.start(AS);
    }
}
