Question

目前我正在开展一个项目。该项目包含声音，我在尝试播放它时遇到了麻烦。

private void playSound(){
    try{
        AudioInputStream audioIn = AudioSystem.getAudioInputStream(this.getClass().getResource("delta/client/gui/resources/sound/ClipOfSound.mp3"));
        Clip clip = AudioSystem.getClip();
        clip.open(audioIn);
        clip.start();
    }catch(Exception err){
        err.printStackTrace();
    }
}

它给了我一个NullPointerException。路径是正确的，我已多次检查它。我不知道问题是什么......任何帮助都非常值得赞赏。
