My program is intended to display 2 panels initially with different images from file Z_pic1.png and Z_pic2.png.WHEN ANY KEY IS PRESSED the displays on the panels should interchange swap. It is not displaying 2 images, but just the image from Z_pic2,png. Any key press has no effect. Wanna find what’s wrong.

My code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

public class Z_LayeredPaneExample1_2 extends JFrame {
private JPanel[] panels;
private JLabel[] imageLabels;

public Z_LayeredPaneExample1_2() {
    setTitle("Panel Swapper");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setSize(800, 600);
    setLocationRelativeTo(null);

    // Create the panel array
    panels = new JPanel[2];
    imageLabels = new JLabel[2];

    // Load the images
    ImageIcon image1 = new ImageIcon("Z_pic1.png");
    ImageIcon image2 = new ImageIcon("Z_pic2.png");

    // Create the panels and add them to the frame
    createPanels(image1, image2);

    // Add a key listener to swap the images when a key is pressed
    addKeyListener(new KeyListener() {
        @Override
        public void keyTyped(KeyEvent e) {
        }

        @Override
        public void keyPressed(KeyEvent e) {
            swapPanels();
        }

        @Override
        public void keyReleased(KeyEvent e) {
        }
    });

    setVisible(true);
}

private void createPanels(ImageIcon image1, ImageIcon image2) {
    // Create the panels and set their layout and background color
    for (int i = 0; i < panels.length; i++) {
        panels[i] = new JPanel();
        panels[i].setLayout(new BorderLayout());
        panels[i].setBackground(Color.WHITE);

        // Add the image to the panel
        imageLabels[i] = new JLabel(i == 0 ? image1 : image2);
        panels[i].add(imageLabels[i], BorderLayout.CENTER);

        // Add the panel to the frame
        add(panels[i], BorderLayout.WEST);
    }
}

private void swapPanels() {
    // Swap the images in the panels
    ImageIcon temp = (ImageIcon) imageLabels[0].getIcon();
    imageLabels[0].setIcon(imageLabels[1].getIcon());
    imageLabels[1].setIcon(temp);
}

public static void main(String[] args) {
    new Z_LayeredPaneExample1_2();
}
}
