Java Detecing when sound stops

Hello I have a sound class for my application and it plays a certain sound when I tell it too. I want to be able to detect when the sound is finished playing so I can then play a different sound without them over lapping here is my sound class:

public class Sound {

public static final Sound cash = new Sound("/cash.wav");
public static final Sound snap = new Sound("/snap.wav");
public static final Sound disarm = new Sound("/disarm.wav");
public static final Sound tp = new Sound("/tp.wav");
public static final Sound select = new Sound("/selectBTN.wav");
public static final Sound scroll = new Sound("/btn.wav");
public static final Sound fire = new Sound("/fire2.wav");

private AudioClip c;

public Sound(String filename) {
    try {
        c = Applet.newAudioClip(Sound.class.getResource(filename));

    } catch (Exception e) {
        e.printStackTrace();
    }
}

public void play() {
    try {
        new Thread() {
            public void run() {
                if (!title.mute) {

                    c.play();
                }
            }
        }.start();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

}

then to play the sound I use this line of code:

   Sound.cash.play();

How can I detect when the sound is finished playing
