Needing to type full path to save file?

Okay, this is my first post here, sorry if i did something wrong. (please let me know if i did aswell)
So i've been trying to make a "data" folder with a audio(.wav) file in it when the runnable jar file is run but for some reason it doesn't work, i've tried to get this working for the last week but i finally kinda gave up on trying to get it working without help(other than searching around the internet) and therefore ask here.
So i have this code:
public static void loop(String path, int volume) {
try {
if (volume > 6) throw new IllegalArgumentException("Requested volume ("+volume+") is higher than allowed. (maximum 6)");
else if (volume < -80) throw new IllegalArgumentException("Requested volume ("+volume+") is lower than allowed. (minimum -80)");
else {
Clip clip = AudioSystem.getClip();
clip.open(AudioSystem.getAudioInputStream(new File(path)));
clip.loop(Clip.LOOP_CONTINUOUSLY);
FloatControl gain = (FloatControl) clip.getControl(FloatControl.Type.MASTER_GAIN);
gain.setValue(volume);
clip.start();
}
} catch (Exception e) {
e.printStackTrace();
}
}
for looping a .wav file continuously and it works, then i try to save the file with this code:
public void save(String music, String output) {
try {
File sound = new File(music);
AudioInputStream ais = AudioSystem.getAudioInputStream(sound);
AudioSystem.write(ais, AudioFileFormat.Type.WAVE, new File(output));
} catch (IOException | UnsupportedAudioFileException e) {
e.printStackTrace();
}
}
And that seems to work aswell when i do something like this:
save("D:\\Eclipse\\eclipse\\workspace\\Test\\data\\music.wav", "C:\\Users\\Karim\\Desktop\\data\\test.wav");
loop("C:\\Users\\Karim\\Desktop\\data\\test.wav", -30);
But if i try to do this instead:
private File jar() {
try {
File jar = new File(Game.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath());
return jar;
} catch (URISyntaxException e) {
e.printStackTrace();
}
return null;
}
private File data = new File(jar().getParentFile().getPath()+File.separator+"\\data");
private File music = new File(data.getPath()+"\\music.wav");
save(music.getPath(), "C:\\Users\\Karim\\Desktop\\data\\test.wav");
loop("C:\\Users\\Karim\\Desktop\\data\\test.wav", -30);
it won't save the file, why is that and what can i do to make it save?
Final Notes:
I'm pretty new to java.
I'm pretty new to programming in itself.
I don't want to use a library, i wanna try to make it work without and i'm so close.
If i forgot to say anything please let me know and i'll edit this post or make a comment.
EDIT: Just wanted to make it clear that this works in the IDE but not when i export it. Also i have the data folder both IN the 'src' folder and beside the 'src' folder, just for testing.

.wav sounds not playing in Java

I am currently using this function to play .WAV files
public void playSound(String sound){
try {
// Open an audio input stream.
URL url = this.getClass().getClassLoader().getResource(sound);
AudioInputStream audioIn = AudioSystem.getAudioInputStream(url);
// Get a sound clip resource.
Clip clip = AudioSystem.getClip();
// Open audio clip and load samples from the audio input stream.
clip.open(audioIn);
clip.start();
} catch (UnsupportedAudioFileException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (LineUnavailableException e) {
e.printStackTrace();
}
}
The problem is that no sound is being played when I call the function on a file, no errors or exceptions are thrown or whatsoever the program just starts and stops, no sound plays, I tried with a lot of different .WAV files with no success.

The programm stops before it has time to play the sound since start is non-blocking.
Try the following :
clip.start();
clip.drain();
clip.close();

This works for me:
public void sound() {
try{
AudioInputStream ais = AudioSystem.getAudioInputStream(new File("./sounds/player-laser.wav"));
Clip test = AudioSystem.getClip();
test.open(ais);
test.loop(0);
}catch(Exception ex){
ex.printStackTrace();
}
}

How to give path of the music file that is inside the Java package?

I created a package named sounds in my Java project and my sound is in this package. However, I get an java.io.FileNotFoundException error with this code. So how can I give the path of this file?
path="sounds/hit.wav"
path is given like above
public class Sound {
AudioInputStream audio;
Clip clip;
//String path;
public void play(String path)
{
try{
File soundFile =new File(path);
audio = AudioSystem.getAudioInputStream(soundFile);
clip = AudioSystem.getClip();
clip.open(audio);
clip.start();
}
catch(Exception e)
{
e.printStackTrace();
}
}
I also tried this one and it gives an IOException:
clip.open(AudioSystem.getAudioInputStream(
new BufferedInputStream(getClass().getResourceAsStream("/sounds/hit.wav"))));
Can you please tell me how can I solve this problem?
Here is my file structure:

URL urlToHit = this.getClass().getResource("/edu/iyte/ceng316/resource/hit.wav");
System.out.println(urlToHot);

Maybe:
clip.open(AudioSystem.getAudioInputStream(getClass().getResourceAsStream("sounds/hit.wav"));

No sound after export to jar

I have problem with my app. When I run app in Eclipse, sound played well, but if I export app to runnable jar, sound doesn't work.
Method, where sound is played:
public static synchronized void playSound()
{
new Thread(new Runnable()
{
// The wrapper thread is unnecessary, unless it blocks on the
// Clip finishing; see comments.
public void run()
{
try
{
Clip clip = AudioSystem.getClip();
AudioInputStream inputStream = AudioSystem.getAudioInputStream(getClass().getResourceAsStream("sound.wav"));
clip = AudioSystem.getClip();
clip.open(inputStream);
clip.start();
}
catch (Exception e)
{
System.err.println(e.getMessage());
}
}
}).start();
}
Where can be a mistake?

The problem is in this
AudioInputStream inputStream = AudioSystem.getAudioInputStream(getClass().getResourceAsStream("sound.wav"));
in JAR file isn't working getResourceAsStream for any reason. So I replace it with getResource:
AudioInputStream inputStream = AudioSystem.getAudioInputStream(getClass().getResource("sound.wav"));
and this works fine.

Java Sound Repeated Play

I'm trying to add sound to a game I've been working on, and I'm having trouble getting the sounds to play more than once. I think I've worked out the cause, but I'm not sure how to solve it. I'm using an enumerator I found while searching for a Java sound tutorial.
The problem is that I'm calling the sound within a thread, in my update() method, and that each time I call the play() method of the sound, it starts the clip over. The first time it's called, the sound plays fine (I may get a bit of a freeze), but all attempts afterwards to play the sound fail. I don't get any exceptions or errors, the sound just doesn't play.
public enum Sounds {
RIFLE("rifle_fire.wav");
private Clip clip;
Sounds(String filename) {
openClip(filename);
}
public synchronized void openClip(String filename) {
try {
URL audioFile = Sounds.class.getResource("/resources/sounds/" + filename);
AudioInputStream audio = AudioSystem.getAudioInputStream(audioFile);
AudioFormat format = audio.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, format);
clip = (Clip) AudioSystem.getLine(info);
clip.open(audio);
} catch (UnsupportedAudioFileException uae) {
System.out.println(uae);
} catch (IOException ioe) {
System.out.println(ioe);
} catch (LineUnavailableException lue) {
System.out.println(lue);
}
}
public synchronized void play() {
if(clip.isRunning()) clip.stop();
clip.setFramePosition(0);
clip.start();
}
public static void init() {
values();
}
}
That is the enumerator I use. It's called from the update() method of my main thread, which is updated every 20 ms. In the update method, I call it like this.
// If the left mouse button is held down, create a new projectile.
if(Globals.buttons[0] && !player.isOnCooldown()) {
createParticle(pAngle);
Sounds.RIFLE.play();
}
Someone suggested I need to close the line after using it, but the sound is only opened once... why would I need to close it? Anyone know what the problem is?
