java - 音频文件未在Java中播放

Question

我正在尝试使用MediaPlayer播放音频文件，但无法正常工作并显示

Exception in thread "main" java.lang.IllegalArgumentException: uri.getScheme() == null! uri == 'audio.mp3'

谁能帮我解决这个问题？

这是我的代码:

package playaudio;

import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;

public class PlayAudio {

    public static void main(String[] args) {

        String fileName = "audio.mp3";
        Media playFile = new Media(fileName);
        MediaPlayer mediaPlayer = new MediaPlayer(playFile);
        mediaPlayer.play();
    }

}

编辑:当我尝试将文件名转换为URI时，它显示以下异常。

Exception in thread "Thread-0" java.lang.IllegalStateException: Toolkit not initialized

码:

package playaudio;

import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;

public class PlayAudio {

    public static void main(String[] args) {

        String fileName = "audio.mp3";
        Media playFile = new Media(Paths.get(fileName).toUri().toString());
        MediaPlayer mediaPlayer = new MediaPlayer(playFile);
        mediaPlayer.play();
    }

}

Media的构造函数实际上需要一个URI，这意味着您必须将文件名转换为URI，请尝试以下操作:
Media media = new Media(Paths.get(fileName).toUri().toString());
