Java desktop application,


Answers ( 1 )


    Java desktop applications are software applications that run on a desktop or laptop computer using the Java programming language. These applications can be developed using various Java technologies, including Swing, JavaFX, and AWT (Abstract Window Toolkit).


    Swing is a part of Java Foundation Classes (JFC) and provides a set of GUI components for developing rich desktop applications. It is a lightweight GUI toolkit that includes a wide variety of widgets such as buttons, text fields, tables, lists, and more.

    Example of creating a simple Swing application:

    import javax.swing.JFrame;
    import javax.swing.JLabel;
    public class HelloWorldSwing {
        private static void createAndShowGUI() {
            // Create the window
            JFrame frame = new JFrame("Hello World Swing");
            // Add a "Hello World" label
            JLabel label = new JLabel("Hello World");
            // Display the window
        public static void main(String[] args) {
            // Schedule a job for the event-dispatching thread
            javax.swing.SwingUtilities.invokeLater(new Runnable() {
                public void run() {


    JavaFX is a modern set of graphics and media packages that enables developers to design, create, test, debug, and deploy rich client applications that operate consistently across diverse platforms. JavaFX has replaced Swing as the recommended GUI toolkit for Java.

    Example of creating a simple JavaFX application:

    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 {
        public void start(Stage primaryStage) {
            Label label = new Label("Hello, JavaFX!");
            StackPane root = new StackPane();
            Scene scene = new Scene(root, 300, 250);
            primaryStage.setTitle("Hello World!");
        public static void main(String[] args) {

    AWT (Abstract Window Toolkit)

    AWT is Java's original platform-independent windowing, graphics, and user-interface widget toolkit. It is part of the Java Foundation Classes (JFC) and is used less frequently today, as Swing and JavaFX offer more versatile and modern components.

    Example of creating a simple AWT application:

    import java.awt.Frame;
    import java.awt.Label;
    import java.awt.event.WindowAdapter;
    import java.awt.event.WindowEvent;
    public class HelloWorldAWT {
        public static void main(String[] args) {
            Frame frame = new Frame("Hello World AWT");
            frame.add(new Label("Hello, AWT!"), "Center");
            frame.setSize(300, 200);
            frame.addWindowListener(new WindowAdapter() {
                public void windowClosing(WindowEvent windowEvent){

    Each of these technologies has its use cases and preferred scenarios. Swing and JavaFX are more commonly used for modern Java desktop applications, with JavaFX being the more recent and feature-rich option. AWT is primarily of historical interest, though it is still used in some contexts.
