To change components in containers you need to remove the old ones and replace them with new ones, then you need to validate the container before you repaint it.
final JLabel label1 = new JLabel("Label 1");
final JLabel label2 = new JLabel("Label2");
final JPanel lp = new JPanel( new BorderLayout() );
lp.add(label1, BorderLayout.NORTH );
JButton changer = new JButton("Click to change");
changer.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e) {
if(label1.isShowing()) {
lp.remove(label1);
lp.add(label2, BorderLayout.NORTH);
} else {
lp.remove(label2);
lp.add(label1, BorderLayout.NORTH);
}
lp.validate();
lp.repaint();
}
} );
lp.add(changer, BorderLayout.SOUTH);
Something like this should do what you require. Work more on it the necessary effect.

Your description of the problem suggests that you may actually
want to use CardLayout rather than adding/removing. Alternately,
post a short, compileable, executable example and we can go
over specifics. As far as adding/removing goes, icewaker has
shown you the basic idea pretty clearly.
