Concatenate audio wave

[aroua rourou]

Here is my code that concatenates four wav files and produces wavAppended.wav. This concatenated file nicely plays in Windows Media Player. But through the PlaySound class, only the one.wav can be heard. Can anyone help?

class PlaySound extends Object implements LineListener
{
   File soundFile;
   JDialog playingDialog;
   Clip clip;

   public void PlaySnd(String s) throws Exception
   {
      JFileChooser chooser = new JFileChooser();
      soundFile = new File(s);
      Line.Info linfo = new Line.Info(Clip.class);
      Line line = AudioSystem.getLine(linfo);
      clip = (Clip) line;
      clip.addLineListener(this);
      AudioInputStream ais = AudioSystem.getAudioInputStream(soundFile);
      clip.open(ais);
      clip.start();
    }

    public void update(LineEvent le)
    {
        LineEvent.Type type = le.getType();
        playingDialog.setVisible(false);
        clip.stop();
        clip.close();
     }
}
[code=java]
public class Main
{
   public static void main(String[] args)
   {
      int i;
      String wavFile[] = new String[4];
      wavFile[0] = "D://one.wav";
      wavFile[1] = "D://two.wav";
      wavFile[2] = "D://three.wav";
      wavFile[3] = "D://space.au";
      AudioInputStream appendedFiles;

      try
      {
          AudioInputStream clip0=AudioSystem.getAudioInputStream(new File(wavFile[0]));
          AudioInputStream clip1=AudioSystem.getAudioInputStream(new File(wavFile[1]));
          AudioInputStream clip3;

          for (i=0;i<4;i++)
          {
              appendedFiles = new AudioInputStream(
                 new SequenceInputStream(clip0, clip1),
              clip0.getFormat(),
              clip0.getFrameLength() + clip1.getFrameLength());
              AudioSystem.write(appendedFiles, AudioFileFormat.Type.WAVE, new File("D:\\wavAppended.wav"));

              clip3 = AudioSystem.getAudioInputStream(new File("D:\\wavAppended.wav"));
              clip0=clip3;
              clip1 = AudioSystem.getAudioInputStream(new File(wavFile[i+2]));

            }

            PlaySound p = new PlaySound();
            p.PlaySnd("D://wavAppended.wav");
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}
