Why doesnt a sound play when I change the path?

Question

Hi. I am trying to play a background sound in my program and so far, after searching and reading lots of posts I finally have a "TaDa" sound playing once when the program starts. But what I want is a sound to be looped everytime I start a program. That sound will be in the same folder as the program.
This is the code that I put in public static void main() to play the sound:
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
java_testt b = new java_test();
b.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
b.startApp();
private void startApp()
{playStartupSound();}
private void endApp() {System.exit(0);}
private void playStartupSound() {
Runnable soundPlayer = new Runnable() {
public void run() {
try {                                                                                    
File tadaSound = new File(System.getenv("windir") + "/" + //This is the windows tada sound. All I want is
"media/tada.wav"); //to change the path to another sound
AudioInputStream audioInputStream = AudioSystem
.getAudioInputStream(new FileInputStream(tadaSound));
AudioFormat audioFormat = audioInputStream
.getFormat();
DataLine.Info dataLineInfo = new DataLine.Info(
Clip.class, audioFormat);
Clip clip = (Clip) AudioSystem
.getLine(dataLineInfo);
clip.open(audioInputStream);
clip.start();
} catch (Exception e) {
e.printStackTrace();
Thread soundPlayingThread = new Thread(soundPlayer);
soundPlayingThread.start();
Does anyone know how to choose another sound in the same folder as java_test and make it work with this code because when I change the ath it doesnt run.
Thanks.

Please put your code between the code tags. It's much better readable then.
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
java_testt b = new java_test();
b.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
b.startApp();
private void startApp()
{playStartupSound();}
private void endApp() {System.exit(0);}
private void playStartupSound() {
Runnable soundPlayer = new Runnable() {
public void run() {
try {
File tadaSound = new File(System.getenv("windir") "/" //This is the windows tada sound. All I want is
"media/tada.wav"); //to change the path to another sound
AudioInputStream audioInputStream = AudioSystem
.getAudioInputStream(new FileInputStream(tadaSound));
AudioFormat audioFormat = audioInputStream
.getFormat();
DataLine.Info dataLineInfo = new DataLine.Info(
Clip.class, audioFormat);
Clip clip = (Clip) AudioSystem
.getLine(dataLineInfo);
clip.open(audioInputStream);
clip.start();
} catch (Exception e) {
e.printStackTrace();
Thread soundPlayingThread = new Thread(soundPlayer);
soundPlayingThread.start();
}
