Java Code

The JFrame uses a BorderLayout to position two JPanels, one above the other. The top panel uses the FlowLayout to show a "Switch Card" button which controls which card is show in the bottom panel. The bottom panel uses the CardLayout to position two JPanels. The JPanel on show is determined by the CardLayout (which is changed to the next card by pressing the "Switch Card" button). 

//Imports are listed in full to show what's being used
//could just import javax.swing.* and java.awt.* etc..

//Use the event dispatch thread for Swing components
EventQueue.invokeLater(new Runnable()
public void run()
new CardLayoutExample();
public CardLayoutExample()
guiFrame = new JFrame();
//make sure the program exits when the frame closes
guiFrame.setTitle("CardLayout Example");
//This will center the JFrame in the middle of the screen
guiFrame.setLayout(new BorderLayout());
//creating a border to highlight the JPanel areas
Border outline = BorderFactory.createLineBorder(;
JPanel tabsPanel = new JPanel();
JButton switchCards = new JButton("Switch Card");
switchCards.setActionCommand("Switch Card");
switchCards.addActionListener(new ActionListener()

cardPanel.add(firstCard, "Fruits");
cardPanel.add(secondCard, "Veggies");
//All the buttons are following the same pattern
//so create them all in one place.
private void addButton(Container parent, String name)
JButton but = new JButton(name);
