Trying to get an applause sound to play when jframe opens - swing

Question

First i will say i have my Jframe opening and staying open for 10 seconds.
I wrote some games for kids to display to them what a future in programming could be or computer science... anyway
Whomever wins I have another Jframe designed to pop up when it does i would like a sound clip to play. Currently the sound clip is in the source folder and i have a little method to play it but it is not working. Here is the code
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
import java.io.IOException;
import java.net.URL;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;

import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;
public class HoorayWithTimer extends javax.swing.JFrame {
int counter;
public HoorayWithTimer() {
initComponents();
Clip click = clipOpen("applause3.wav");// should open the clip
clipStart(click);
}//end of public HorrayWithTimer()

Answer 1

I think problem is here clipOpen("applause3.wav"). Try to use /applause3.wav. Also where is your wav file? For example it works for my path "/res/1.mp3", 1.mp3 file exists in res folder in folder src.
EDIT: Replace your code and watch exception, it's here not in clipStart method:
private Clip clipOpen(String name){
URL url = getClass().getResource(name);
try {
AudioInputStream stream = AudioSystem.getAudioInputStream(url);
Clip clip = AudioSystem.getClip();
clip.open(stream);
return clip;
} catch (UnsupportedAudioFileException | IOException | LineUnavailableException ex) {
ex.printStackTrace()
}
return null;
}
