Using a CardLayout Manager

import java.awt.CardLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TryCardLayout extends JPanel implements ActionListener {
  CardLayout card = new CardLayout(50, 50); // Create layout
  public TryCardLayout() {
    setLayout(card);
    JButton button;
    for (int i = 1; i <= 6; i++) {
      add(button = new JButton(" Press " + i), "Card" + i); // Add a button
      button.addActionListener(this); // Add listener for button
    }
  }
  // Handle button events
  public void actionPerformed(ActionEvent e) {
    card.next(this); // Switch to the next card
  }
  public static void main(String[] args) {
    JFrame aWindow = new JFrame();
    aWindow.setBounds(30, 30, 300, 300);
    aWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    aWindow.getContentPane().add(new TryCardLayout());
    aWindow.setVisible(true);
  }
}

What is the CardLayout

1. Place components like a deck of cards.
2. Only the "top" component is visible at any one time.

import java.awt.CardLayout;
import java.awt.Color;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class CardLayoutBehaviour extends JFrame {
  protected CardLayout layout;
  public static void main(String[] args) {
    CardLayoutBehaviour ct = new CardLayoutBehaviour();
    ct.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    ct.displayTab("Green Tab");
    ct.setSize(400, 300);
    ct.setVisible(true);
  }
  public CardLayoutBehaviour() {
    JPanel tab;
    Container pane = getContentPane();
    layout = new CardLayout();
    pane.setLayout(layout);
    tab = new JPanel();
    tab.setBackground(Color.red);
    pane.add(tab, "Red Tab");
    tab = new JPanel();
    tab.setBackground(Color.green);
    pane.add(tab, "Green Tab");
    tab = new JPanel();
    tab.setBackground(Color.blue);
    pane.add(tab, "Blue Tab");
  }
  public void displayTab(String name) {
    layout.show(this.getContentPane(), name);
  }
}
