How to play audio in an application?? (HELP ME PLEASE!!)

Question

Hi! I'm studying computer science and I'm programming in Java for my last project of this period. I've been trying to play sound in an application but I haven't been able to. My teacher gave me a piece of code that looked like this:
try{
URL url=new URL("http://hostname/audio.au");
AudioClip ac=Applet.new AudioClip(url);
ac.play();
}catch (MalformedURLException e){
This is the code for my program:
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.applet.AudioClip;
import java.applet.AudioClip.*;
public class Sonido extends Frame implements AudioClip{
     public Sonido(){
          this.setSize(new Dimension(300,200));
          this.setTitle("Testing");
          this.setLayout(new BorderLayout());
          this.add(new Button("Music"), BorderLayout.CENTER);
          addWindowListener(new WindowAdapter(){
               public void windowClosing(WindowEvent e){
                    System.exit(0);
     public static void main(String [] args){
          Sonido sound=new Sonido();
          sound.show();
          try{
               URL url=new URL("C://toolate02.au");
               AudioClip ac=new AudioClip(url);
               ac.play();
          catch(MalformedURLException e){
It is only a test but I have to get it to work because the teacher wants the sound to play forever! (with loop() I guess). Anyway, I don't know how to implement the methods of the AudioClip interface. Any help would be great!!! Thank you very much.

This is probably too late to help you, but if you're using Java 1.3 or higher, you can use the javax.sound.sampled package to play .au's, .aiff's, and .wav's (but not .mp3's... support for those comes from Java Media Framework [JMF] or QuickTime for Java [QTJ])
Anyways, this app plays a single file specified on the command line, like:
java SimpleSound mailbag.aiff
import javax.sound.sampled.*;
import java.io.*;
public class SimpleSound extends Object {
    public static void main (String[] args) {
        if (args.length < 1) {
            System.out.println ("Usage: SimpleSound <file-path>");
            return;
        try {
            Line.Info linfo = new Line.Info (Clip.class);
            Line line = AudioSystem.getLine (linfo);
            Clip clip = (Clip) line;
            File file = new File (args[0]);
            AudioInputStream ais = AudioSystem.getAudioInputStream(file);
            clip.open (ais);
            clip.start();
        } catch (Exception e) {
            e.printStackTrace();
}Works for me on Mac OS X. .aiff's sound good but .au's sound awful. Your mileage may vary.
