Help on playing sound

Question

Hi there,
I want to play a sound file without the dependence
on any web browser. Below is my simple Java code.
When I test it on DOS prompt, it can play the desired
sound file. However, the system keep hanging after
the play of the sound. Can anyone tell me what's
the problem of my code? Alternatively, is there any
better Java code (not applet) to play a sound file?
import java.io.*;
import java.net.*;
import java.applet.*;
public class testAudio{
     public static void main(String args[]){
          try{
               URL baseURL = new URL("file:" + System.getProperty("user.dir") + "/");
               String relativeURL = "spacemusic.au"; // any audio file you want to play
               URL completeURL = new URL(baseURL, relativeURL);
               System.out.println(completeURL);
               AudioClip sound = Applet.newAudioClip(completeURL);
               if (sound == null) {
          System.out.println("Sound " + relativeURL + " not loaded yet.");
               sound.play();
          catch (MalformedURLException e){
               System.err.println(e.getMessage());
Thanks a bunch,

Using this method to play a sound spawns a thread that plays the sound (so the app isn't blocked until the sound finishes). Doing this stops the app from terminating (much like if you created a Frame object). You can use System.exit(0); to force an application termination. I've found using AudioClip to very bug-prone. Its much better to use the javax.swing packages:
