Java - sleep in a for loop doesn't work (as desired)

Question

Hey all,
I'm trying to get a draw animation when the mouse is released (after dragging an object to a set area on the screen) - hence I'm trying to do this via a for loop with a small sleep() delay. However it isn't working. The delay is there, but nothing changes until the end of the for loop and then you only see the final repaint() [i.e. instead of each iteration in the for loop]:
// This program is concerned with this and the mouseDragged methods
     public void mouseReleased(MouseEvent e)
          for( int c = 0; c < xButton.length; c++)
               if( xButton[c] >= xRandWeight && xButton[c] <= (xRandWeight+50) && yButton[c] >= yRandWeight && yButton[c] <= (yRandWeight+50) )
                    // Have an animation for the scales re-adjusting
                    if( c == 0 )
                         currWeight = (int)(scales.getWeight2());
                         desiredWeight = Integer.parseInt(b1.getLabel());
                         if( desiredWeight >= currWeight )
                              // More efficient than putting this subtraction straight into for loop
                              difference = desiredWeight - currWeight;
                              for( int count = 1 ; count <= difference ; count++ )
                                   scales.setWeight2(currWeight+count);
                                   repaint();
                                   try
                                        Thread.currentThread().sleep(100);
                                   catch (InterruptedException in)
                                        in.printStackTrace();
                         else
                              difference = currWeight - desiredWeight;
                              for( int count = 1 ; count <= difference ; count++ )
                                   scales.setWeight2(currWeight-count);
                                   repaint();
     }Any ideas on how to fix this/meet the goal would be greatly appreciated :)
Thanks,
Tristan Perry

My program isn't being written in SWINGFirst, it's Swing, not SWING. It's not an acronym.
Perhaps you would like to tell us which windowing toolkit you are using, so that you can get better responses. Or is that a closely guarded secret? <sarcasm/>
I'm very new to JavaSo ditch the GUI stuff and get a foundation first.
