About JPanels and menus the best away

I am planning to make a program that in the top of the contentPane has a menubar.

Under this menubar another JPanel, here is what I did (it works), but I don't know if this is the best way:

I made a lot of JPanels with different buttons, I want that a JMenuItem changes the screen(JPanel)

So what I did for each JMenuItem that set the specific JPanel(all panels are in the same position in the GridBagLayout, but all start with .setVisible(false);)

jemnuitem1.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {

        jpanelItem1.setVisible(true);
        jpanelItem2.setVisible(false);
        jpanelItem3.setVisible(false);
    }
});     

jemnuitem2.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {

        jpanelItem1.setVisible(false);
        jpanelItem2.setVisible(true);
        jpanelItem3.setVisible(false);
    }
});     

jemnuitem3.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {

        jpanelItem1.setVisible(false);
        jpanelItem2.setVisible(false);
        jpanelItem3.setVisible(true);
    }
});

This works, but I want to know if there is a way better to do this, or can I have a big problem doing this, because if this works, its fine for me work in this way, but I want the help of others that already made something similar.

You should use CardLayout. Then you can switch the visible panel instead of writing clumsy code like you have now.
