Thread in Swing

How to implement animation in swing using thread. Whenever I try using Thread.sleep than it is not working
ex- if my pro have 3 sleep of 20 second than whole o/p is displaying after 60 second nothing b/w that.
I am changing value in a table or changing foreground of Label after clicking on a button

I bet you make the EDT (Event Dispatch Thread) sleep somewhere in a listener or in a method (in)directly called from there; right? The wrong thread sleeps then and it can't draw anything.

Make another thread sleep and use the SwingUtilities class to invoke some other method that calls the repaint() method at the end. The event thread will draw the stuff as soon as possible afterwards then.

kind regards,

@goelvivek
Google for "java animation" and you'll find numerous examples. They all use a separate thread that prepares the drawing parameters for the EDT thread to draw its image.

kind regards,
