    Study Notes

    To showcase an image in Java Swing, you can follow these steps:

    Loading an Image into a JPanel

    Load the image from its location using an ImageIcon. Set the image in the center of the JLabel within the JPanel. Finally, add the panel to the layout manager, such as BorderLayout, and make it visible.

    public JFrame displayImageExample() {
        JFrame frame = new JFrame("Display Image Example");
        frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
        
        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        
        JLabel label = new JLabel();
        ImageIcon imageIcon = new ImageIcon("path/to/your/image.jpg");
        label.setIcon(imageIcon);
        panel.add(label, BorderLayout.CENTER);
        
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
        
        return frame;
    }
    

    Optional: Adding Image to a JButton

    An alternative method is to add the image directly to a JButton. To do this, you can create an instance of ImageIcon using the path to your image and then set it as the icon for the button. Finally, append the button to the panel layout manager.

    public JFrame displayImageExample() {
        JFrame frame = new JFrame("Display Image Example");
        frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
        
        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        
        JButton button = new JButton(new ImageIcon("path/to/your/image.jpg"));
        panel.add(button, BorderLayout.CENTER);
        
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
        
        return frame;
    }
    

    By following these methods, you will be able to effectively showcase images in Java Swing.
