Java如何播放从文件选择器中选择的mp3文件

Question

您好，我已经创建了一个文件选择器，我想知道是否有任何可能的方法来播放我可以从文件选择器中选择的 mp3 文件。如果可以的话如何实现？感谢您提前提供的建议。显然，当我单击文件时，没有任何反应，我需要的是单击 mp3 文件，当我点击打开时，我就可以收听它了。

这是我的文件选择器的代码。

  JFileChooser chooser = new JFileChooser();
       File F = new File("C:/");
       File namedir;
       File namepath;

       chooser.setCurrentDirectory(F);
       chooser.showOpenDialog(null);
       chooser.setDialogTitle("Choose file to play");
       chooser.setApproveButtonText("Play");
  namedir = chooser.getCurrentDirectory();
  namepath = chooser.getSelectedFile();
  System.out.print("the name of the the directory is "+namedir.getName());
  System.out.print("the name of the the path is "+namepath.getAbsolutePath());
   String fileName=null;

String fileName=null;
JFileChooser chooser = new JFileChooser();
    FileNameExtensionFilter filter = new FileNameExtensionFilter(
        "MP3 Files", "mp3");
    chooser.setFileFilter(filter);
    int returnVal = chooser.showOpenDialog(parent);
    if(returnVal == JFileChooser.APPROVE_OPTION) {
       fileName=     chooser.getSelectedFile().getName();
    }
MediaPlayer mediaPlayer = new MediaPlayer(new Media(fileName));
mediaPlayer.play();

这是完整的工作代码
