Loop sound in java directory

Question

I need some explanation with a sound class. So I made a Sound object class to allow me to simply call any sound I need to at a later time. I have my file in a sounds folder in the same directory as the java files. So it's ~\Game\sounds\music.wav Now every time I execute this code from the main class via creating an object then calling it, it gives me file doesn't exist, am I pointing incorrectly into the file? Currently my fileName is only "music.wav" how could I just point it to the sounds directory without hard coding the directory so it can work on any cpu.

public Sound(String fileName) {
        try {
                File file = new File(fileName);
                if (file.exists()) {
                    myClip = (AudioClip) Applet.newAudioClip(file.toURI().toURL());
                } else {
                    throw new RuntimeException("Sound: file not found: " + fileName);
                }
        } catch (MalformedURLException e) {
            throw new RuntimeException("Sound: malformed URL: " + e);
        }
}
public void play() {
    myClip.play();
}

I hope this code will helping you. I created a package under src named resources. Under resources package, I put all my sound files.

import java.io.*;
import java.net.URL;
import javax.sound.sampled.*;

public enum SoundEffect  {


    BUSY("resources/phone-busy.wav"),   
    CALLING("resources/phone-calling.wav"),         
    DISCONNECT("resources/phone-disconnect.wav"),
    RING("resources/telephone-ring.wav");  

    // Each sound effect has its own clip, loaded with its own sound file.
    private Clip clip;
    private URL url;
    private AudioInputStream audioInputStream;

    // Constructor to construct each element of the enum with its own sound file.
    SoundEffect(String soundFileName) {
        try {
            // Use URL (instead of File) to read from disk and JAR.
            this.url = this.getClass().getClassLoader().getResource(soundFileName);
            // Set up an audio input stream piped from the sound file.
            this.audioInputStream = AudioSystem.getAudioInputStream(url);
            // Get a clip resource.
            clip = AudioSystem.getClip();
            // Open audio clip and load samples from the audio input stream.
            clip.open(audioInputStream);

        } catch (UnsupportedAudioFileException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (LineUnavailableException e) {
            e.printStackTrace();
        }
    }

    // Play or Re-play the sound effect from the beginning, by rewinding.
    public void play() {

        clip.loop(Clip.LOOP_CONTINUOUSLY); 

    }

    public void stop(){

        clip.stop();   // Stop the player if it is still running
        clip.flush();
        clip.setFramePosition(0);
    }

    // Optional static method to pre-load all the sound files.
    static void init() {
        values(); // calls the constructor for all the elements
    }

    public boolean isActive(){

        return clip.isActive();
    }

    public boolean isOpen() {

        return clip.isOpen();
    }

    public void setFramePosition() {
        clip.setFramePosition(0);

    }

}

This Class is for testing the SoundEffect enum in a Swing application
