  Thanks.
         I meant javax.swing.JPanel only. I have a JFrame and on it a
1024x768 image will be displayed, and a JPanel with 5 JButtons , two
JLabels will be added to the JFrame. When the user presses a JButton,
the image will be changed programmatically, and the JPanel will be
replaced by another JPanel with a different set of JButtons(5 again)
and JLabels.

        I want to know, how to find the amount of memory for a JPanel
with 5 JButtons and 2 JLabels.

Thanks in advance.

Yes, yes, we got that.  Did you try Andrew's advice?
