Making a Dialog Visible and then Invisible

I was wondering if there's a simple way to make a Dialog visible for a very short period of time and then have it turn invisible. Or even if there's a possibility to do this instantaneously.

Cheers, Kesh

In a method do this:

Thread t = new Thread() {
  public void run() {
    try {
     Thread.sleep(5000);
    }
    catch(Exception ex) {
    }
    dialog.setVisible(false);
  }
t.start();
dialog.setVisible(true);
