java - AudioClip 不起作用，但它应该

Question

我一直在尝试在java中播放声音，但我被卡住了。

public class Audioapp extends JApplet
{

    public class Sound{
        public AudioClip song;
        public URL songPath;
        Sound(){

            try{

               songPath = new URL(getCodeBase(), "leftfordeath.wav"); 

               song = Applet.newAudioClip(songPath); 

            }
            catch (Exception e) {}

        }
        public void playSoundOnce(){
            song.play();
        }
    }

    public void init(){
       Sound test = new Sound();
       test.playSoundOnce();
    }

}

当我从 main 中调用 init 时，它说 Song.play(); 上有一个 nullPointerExeption；我做错了什么，请帮忙...

尝试将此代码替换为 PlaysoundOnce 代码，看看效果如何。

public void playSoundOnce() 
{
  try
  {
    InputStream inputStream = getClass().getResourceAsStream(leftfordeath.wav);
    AudioStream audioStream = new AudioStream(inputStream);
    AudioPlayer.player.start(audioStream);
  }
  catch (Exception e)
  {
    if (debugFileWriter!=null) e.printStackTrace(debugFileWriter);
  }
}
