如何在java application中播放声音

Question

如何在java application中播放声音，求大神赐教。。

Answer 1

public class JavaAudioPlaySoundExample
{
  public static void main(String[] args) 
  throws Exception
  {
    // open the sound file as a Java input stream
    String gongFile = "/Users/al/DevDaily/Projects/MeditationApp/resources/gong.au";
    InputStream in = new FileInputStream(gongFile);    // create an audiostream from the inputstream
    AudioStream audioStream = new AudioStream(in);    // play the audio clip with the audioplayer class
    AudioPlayer.player.start(audioStream);
  }
}

Answer 2

不能识别AudioStream这个类。。
