Is it possible to have 2 JPanels in a Border layout at the same location?

I'm writing a game which uses a border layout with a JPanel using BorderLayout.CENTER. What I'd like to be able to do is sometimes hide this panel and replace it with another panel with different information. I added both to the container and set visibility of one of them to false. Then later I try: ``` panel1.setVisible(false); panel2.setVisible(true); ``` but this doesn't display the new panel. I just see gray. Any ideas? TIA
