I am playing a sound. How can I know when the sound terninates of playing. I
am using the next class on my program:

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

public class Sound {
  File sf=new File("mySound.wav");
  AudioFileFormat aff;
  AudioInputStream ais;

  public Sound() {
    try {
      aff = AudioSystem.getAudioFileFormat(sf);
      //System.out.println(aff);

      ais = AudioSystem.getAudioInputStream(sf);

      AudioFormat af = aff.getFormat();

      DataLine.Info info = new DataLine.Info(
          Clip.class,
          ais.getFormat(),
          ( (int) ais.getFrameLength() *
           af.getFrameSize()));

      Clip ol = (Clip) AudioSystem.getLine(info);

      ol.open(ais);

      ol.loop(3);
    }
    catch (UnsupportedAudioFileException ee) {}
    catch (IOException ea) {}
    catch (LineUnavailableException LUE) {}
      System.out.println("Error")    ;

  }
}
