I presume that you did not start another thread to run this code, and if 
so, that is your problem.  The repaint() method does not actually paint 
the label, rather it schedules it to be repainted.  The actual paint 
operation is done on the AWT event thread.

Your code is (I presume) running on the event thread, so the paint() will 
not occur until your code is complete, and returns control to the event 
dispatcher.  You would have to run your code in a separate thread to 
ensure that this actually gets painted.

You would also have to do something to slow things down.  Even in a 
separate thread, your code would probably run to completion before the 
paint code got a change to run.  If you added a sleep() before each label 
update, it should work.
