How to add music into my java project?

Question: I can’t figure out how to add music to my java replit project

My code plays music fine on Eclipse, probably since that runs on my local machine. But I don’t know how to add it for Replit. All the resources, including the tutorial provided by replit, are for python. But I am using java.

Repl link: https://replit.com/@NikhilGarg7/Java-Project?v=1

This is my code for the music itself

import java.io.File;

import javax.sound.sampled.LineEvent;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.swing.JOptionPane;

public class musicStuff 
{

	void playMusic(String musicLocation) 
  {
		
		try 
    {
			File musicPath = new File(musicLocation);
			
			if(musicPath.exists()) 
      {
				AudioInputStream audioInput = AudioSystem.getAudioInputStream(musicPath);
				Clip clip = AudioSystem.getClip();
				clip.open(audioInput);
				clip.start();
				clip.loop(Clip.LOOP_CONTINUOUSLY);
        clip.addLineListener(event -> 
        {
        if(LineEvent.Type.STOP.equals(event.getType())) 
        {
        clip.close();
        }
				});
				//JOptionPane.showMessageDialog(null, "Press OK to stop playing");
			} else 
        {
				System.out.println("Can't find file");
			  }
		}
		
		catch(Exception ex) 
    {
			ex.printStackTrace();
		}
	}
}

This code is in my main class which is actually playing the music.

String filepath = "BetterCallSaul.wav";
              
              musicStuff musicObject = new musicStuff();
              musicObject.playMusic(filepath);

This is the error that happens when I try to run it

Im a beginner to java so im sorry if im missing something haha. Thank yoiu
