为什么它不起作用？我尝试更改文件名，路径，但仍然无法正常工作。我得到了很多例外。我不知道这段代码有什么问题。文件路径 /Users/Mariusz/Music/Audio.mp3
我更改了我的代码，但仍然无法正常工作。
if(e.getActionCommand().equals("Play")) {
bar.setString(file.getName().split(".mp3")[0]);
playSound(file);
}
public void playSound(File file){
String bip = file.toURI().toString();
Media hit = new Media(bip);
MediaPlayer mediaPlayer = new MediaPlayer(hit);
mediaPlayer.play();
}
