Re: How do I play an audio clip in a Java Application?

I've written a simple class which plays audio in an app. Only problem
now is the thread won't die and the app stays up.

import java.io.File;
import java.io.IOException;

import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineEvent;
import javax.sound.sampled.LineListener;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;

/**

    private Thread thread;

    private static SoundPlayer player;

    {
    }

    /**

     */
    public static void playSiren()
    {
        SoundPlayer p = getPlayer();
        p.playSirenFile();
    }

    /**

     */
    private void playSirenFile()
    {
        this.soundFile = new File("./audio/threeHorn.wav");
        thread = new Thread(this);
        thread.setName("SoundPlayer");
        thread.start();
    }

    /**

    public void run()
    {
        try
        {
            AudioInputStream stream = AudioSystem
                    .getAudioInputStream(this.soundFile);
            AudioFormat format = stream.getFormat();

            /**

             * ALAW/ULAW to PCM

            if ((format.getEncoding() == AudioFormat.Encoding.ULAW)
                    || (format.getEncoding() == AudioFormat.Encoding.ALAW))

            clip.start();
