Java GUI Development: JavaFX vs Swing
Java provides two major frameworks for building Graphical User Interfaces (GUI):
1️⃣ Swing – Older, lightweight, and built into Java.
2️⃣ JavaFX – Modern, rich UI toolkit introduced as a replacement for Swing.

1. Swing: The Traditional Java GUI Toolkit
Swing is part of the Java Foundation Classes (JFC) and provides a wide range of GUI components like buttons, text fields, tables, and more.

1.1 Simple Swing Application

import javax.swing.*;



public class SwingExample {

    public static void main(String[] args) {

        // Create a JFrame (Window)

        JFrame frame = new JFrame("Swing Example");

        frame.setSize(400, 300);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);



        // Create a JButton

        JButton button = new JButton("Click Me!");

        frame.add(button);



        // Show the window

        frame.setVisible(true);

    }

}

✅ Output: A simple window with a button labeled "Click Me!".

2. JavaFX: The Modern GUI Toolkit
JavaFX is a more powerful and modern GUI toolkit that supports animations, CSS styling, and better graphics rendering.

2.1 Setting Up JavaFX
Since Java 11, JavaFX is not included in the JDK.

You need to download the JavaFX SDK and add it to your project.

2.2 Simple JavaFX Application

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.layout.StackPane;

import javafx.stage.Stage;



public class JavaFXExample extends Application {

    @Override

    public void start(Stage primaryStage) {

        // Create a Button

        Button button = new Button("Click Me!");



        // Set up the layout

        StackPane root = new StackPane();

        root.getChildren().add(button);



        // Create the Scene

        Scene scene = new Scene(root, 400, 300);



        // Set up the Stage (Window)

        primaryStage.setTitle("JavaFX Example");

        primaryStage.setScene(scene);

        primaryStage.show();

    }



    public static void main(String[] args) {

        launch(args);

    }

}

✅ Output: A window with a "Click Me!" button using JavaFX.

3. Comparing Swing and JavaFX

Feature Swing JavaFX

Performance Slower, older technology Faster, modern rendering engine

UI Design Limited customization Supports CSS for styling

Multimedia Support Basic Supports images, audio, and video easily

Animations Basic support Built-in animation framework

Availability Included in Java 8 Separate library since Java 11

Best For Simple applications Modern, visually appealing apps

4. When to Use Swing vs JavaFX?
✅ Use Swing if:
✔ You need a lightweight GUI with basic components.
✔ You’re working with older Java versions (Java 8 and below).

✅ Use JavaFX if:
✔ You need a modern, feature-rich GUI.
✔ You want better animations, styling, and multimedia support.
✔ You’re working with Java 11+.
