To close one frame and open another you just make the first one invisible (or dispose()) it, then make the second visible (or create new instance of it).

If however you just want to pop up a (modal) dialog you would use one of the methods in the JOptionPane class

what I want to do is, you cannot open other applications w/o closing the popup frame first..

You can't stop the user from switching to other applications if he wants, but if you want to prevent him switching to other windows in your Java app then all you need is a modal JDialog - usually created via JOptionPane

I see... Thanks for your response.
