Formatting Time?

[Dillinger4]

Im trying to create a timer that executes in a seperate thread but i have no clue how to go about formatting the time in h:m:s format. I tried using the java.util.Timer and java.util.TimerTask classes but they are a pain to use so i decided just to use an infinite loop. Thanks

spawnTimerThread(); 


public void spawnTimerThread(){
 DateFormat df = DateFormat.getTimeInstance();
  // how do i format to h:m:s

 Thread timer = new Thread(); 
  t.setDemon(true); // let the vm exit; 
 for(;;){
    timer.sleep(1000);
    // how would i increment the fields
  }
}
