Swaping Panels in a frame?

Question

Hey, I have a frame that has a GridLayout of (1,2) so it can jold 2 Panels of equal size, when I press a button i need the 2 Panels in there to go away so I can put new ones in. This is my code to add Panels:
public void addPanels()
         frame.getContentPane().setLayout(new GridLayout(1,2));
         frame.getContentPane().add(myLeftPanel);
         frame.getContentPane().add(myRightPanel);
     }And I have this one to switch Frames
     public void swapPanels(JPanel leftPanel, JPanel rightPanel)
         myLeftPanel = leftPanel;
         myRightPanel = rightPanel;
         addPanels();
     }I tried the remove(Component comp) meathod and it didn't work and I'v also tried the removeAll() but that didn't work either looks like it removed more then just the Panels because a can't add new ones. Any ideas?

You don't really need to set the content pane's layout each time. Set it once and it is always set. In your addPanels method, you need to call getContentPane().removeAll() then add each panel as you are currently doing then call getConentPane().revalidate().
public void addPanels() {
  Container contentPane = frame.getContentPane();
  contentPane.removeAll();
  contentPane.add(myLeftPanel);
  contentPane.add(myRightPanel);
  contentPane.revalidate();
}
