Answer 1

Simple answer, don't.

Instead, use a CardLayout on the JFrame

This will allow you to setup a series of "views" which you can switch between as needed

Answer 2

Try this. Jframe.remove(JPanel). Then call JFrame.pack() , and possibly JFrame.repaint() in order to refresh the graphics if necessary.

JPanel extends JComponent, so it should work just fine. Remember to substitute JFrame and JPanel in the code above with the names of the frames/panels you are using the methods on.
