Java sound replaying via Clip and AudioInputStream is not working

This is a slightly modified example from the Java Sound info page. https://stackoverflow.com/tags/javasound/info Unfortunately, it only plays the sound once but the intention is twice.

import java.io.File;
import javax.sound.sampled.*;

public class TestNoise {
    public static void main(String[] args) throws Exception {
        File f = new File("/home/brian/drip.wav");
        AudioInputStream ais = AudioSystem.getAudioInputStream(f);

        AudioFormat af = ais.getFormat();
        DataLine.Info info = new DataLine.Info(Clip.class, af);
        Clip clip = (Clip)AudioSystem.getLine(info);

        clip.open(ais);
        clip.start();    // heard this
        Java.killTime(); 
        clip.start();    // NOT HEARD
        Java.killTime();
    }
}

Edit: To understand the answer, see the link provided by Wanderlust or just do what it says in the comment below his answer.

For playing the clip for the second time you must call

clip.start();
clip.stop();

cause after the second call of clip.start(); it is trying to play the file from the place where it stopped previously.
