The elements of a CardLayout are stacked, one on top of the other, like a deck of cards.

In Core Java, the elements of a CardLayout are organized in a stack-like fashion, where only one card is visible at a time. It’s like dealing a deck of cards where only the top card is visible, and you can switch between cards to show a different one.

The CardLayout class is a layout manager for a container that allows you to display different components (cards) in the same area. You can switch between cards programmatically to show the desired component.

Here is a simple example of using CardLayout in Java:

java

import java.awt.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.*;
public class CardLayoutExample {

    public static void main(String[] args) {

        JFrame frame = new JFrame("CardLayout Example");

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.setSize(300, 200);
        JPanel cardPanel = new JPanel();

        CardLayout cardLayout = new CardLayout();

        cardPanel.setLayout(cardLayout);
        JButton card1Button = new JButton("Card 1");

        JButton card2Button = new JButton("Card 2");
        card1Button.addActionListener(new ActionListener() {

            @Override

            public void actionPerformed(ActionEvent e) {

                cardLayout.show(cardPanel, "Card 1");

            }

        });
        card2Button.addActionListener(new ActionListener() {

            @Override

            public void actionPerformed(ActionEvent e) {

                cardLayout.show(cardPanel, "Card 2");

            }

        });
        cardPanel.add(card1Button, "Card 1");

        cardPanel.add(card2Button, "Card 2");

frame.add(cardPanel); frame.setVisible(true); } }

In this example, CardLayout is used to manage two cards (buttons in this case) in a panel. Clicking the buttons switches between the cards, demonstrating the stack-like behavior of CardLayout.
