Java GUI (Graphical User Interface) Programming

Java GUI (Graphical User Interface) Programming is an essential aspect of modern application development, empowering developers to create interactive and visually appealing interfaces. Java provides two main libraries for GUI development: Swing and JavaFX.

Example of Java Swing:

import javax.swing.*;

public class HelloWorldSwing {
public static void createAndShowGUI() {
JFrame frame = new JFrame(“Hello, Swing!”);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JLabel label = new JLabel(“Hello, Swing!”, SwingConstants.CENTER);
frame.getContentPane().add(label);

frame.pack();
frame.setVisible(true);
}

public static void main(String[] args) {
SwingUtilities.invokeLater(HelloWorldSwing::createAndShowGUI);
}
}
Example of JavaFX:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class HelloWorldJavaFX extends Application {
@Override
public void start(Stage primaryStage) {
Label label = new Label(“Hello, JavaFX!”);
StackPane root = new StackPane(label);
Scene scene = new Scene(root, 300, 200);

primaryStage.setTitle(“Hello, JavaFX!”);
primaryStage.setScene(scene);
primaryStage.show();
}

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

Java GUI Programming allows developers to design intuitive graphical applications and forms. GUI components like buttons, text fields, and checkboxes enable users to interact with the application effortlessly.

Example of Creating a Simple Form:

import javax.swing.*;

public class SimpleFormExample {
public static void main(String[] args) {
JFrame frame = new JFrame(“Simple Form”);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JPanel panel = new JPanel();
panel.add(new JLabel(“Name:”));
panel.add(new JTextField(10));
panel.add(new JLabel(“Email:”));
panel.add(new JTextField(15));
panel.add(new JButton(“Submit”));

frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
}
}
