How can I create a simple GUI in Java?

You can use Swing or JavaFX to create a simple GUI. Would you like a basic example using Swing?

Yes, please provide a basic example using Swing.

Here's a simple example:

import javax.swing.*;

public class SimpleGUI {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Simple GUI");
        JButton button = new JButton("Click Me");
        button.addActionListener(e -> JOptionPane.showMessageDialog(frame, "Button Clicked!"));
        frame.add(button);
        frame.setSize(300, 200);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}

This code creates a window with a button that shows a message when clicked.

What libraries do I need to import for this example?

You need to import javax.swing.* for the GUI components. This includes JFrame, JButton, and JOptionPane.

Can I customize the button's appearance?
