Remove Jframe panels

JFrame frame1 = new JFrame("frame");
frame1.setVisible(true);
frame1.setPreferredSize(new Dimension(800, 600));
frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel Panel1 = new JPanel();
JPanel Panel2 = new JPanel();
frame1.add(Panel1,BorderLayout.SOUTH);
frame1.add(Panel2,BorderLayout.North);

How do i do something like this that if something happens the frame is blank 

if(SOMETHINGHAPPENS)
   {
     //remove all panels from frame 1 so i have a blank frame 
    //now i want to add some new panels
   }

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

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.
