how to play mp3 using javafx?

I am trying to play an mp3 file however I am getting an error: Cannot instantiate the type Media. I have no idea how to fix this error. I need the code to play the mp3 file, I also need to get the length of the song in millisecond. Here is my code:

import java.awt.FileDialog;
import java.io.File;
import java.io.IOException;
import java.net.URL;

import javafx.embed.swing.JFXPanel;
import javafx.scene.media.MediaPlayer;

import javax.print.attribute.standard.Media;
import javax.sound.sampled.UnsupportedAudioFileException;
import javax.swing.JFrame;

public class MusicProgress{
  static URL url = null;

public static void main(String[] args) {
    // TODO Auto-generated method stub
    JFrame b = new JFrame();
    final JFXPanel fxPanel = new JFXPanel();
    FileDialog fd = new FileDialog(b, "Pick a file: ", FileDialog.LOAD);
    fd.setVisible(true);
    //final File file = new File(fd.getDirectory()+ fd.getFile());
    try{
    final Media medias = new Media(fd.getDirectory()+ fd.getFile());
    MediaPlayer mediaPlayer = new MediaPlayer(medias);
    } catch (UnsupportedAudioFileException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
 }
}
