无法播放音频剪辑

Question

目前我正在做一个项目。该项目包含声音，我无法尝试播放它们。

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，我已经检查了很多次。我不知道问题是什么.. 任何帮助都非常感谢。

第 84 行： AudioInputStream audioIn = AudioSystem.getAudioInputStream(this.getClass().getResource("delta/client/gui/resources/sound/ClipOfSound.mp3"));

Answer 1

AudioInputStream 与 MP3 类型的文件不兼容。
