Overview of JavaFX - Tutorial

Welcome to this tutorial on JavaFX, a powerful framework for building graphical user interfaces (GUI) in Java. JavaFX provides a rich set of tools and libraries for creating visually appealing and interactive applications.

Example of a JavaFX Application

Let's consider a simple example of a JavaFX application that displays a "Hello, World!" message in a window:

JavaFX Code Example:

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

public class HelloWorld extends Application {
public void start(Stage primaryStage) {
Label label = new Label("Hello, World!");
StackPane root = new StackPane(label);
Scene scene = new Scene(root, 300, 200);

    primaryStage.setTitle("JavaFX Hello World");

public static void main(String[] args) {


This code creates a simple JavaFX application with a label that displays the "Hello, World!" message. It sets up the application window using a StackPane layout and shows it on the screen.

Getting Started with JavaFX

  1. Install Java Development Kit (JDK) version 8 or later, which includes JavaFX.
  2. Create a new Java project in your preferred Integrated Development Environment (IDE).
  3. Add the JavaFX libraries to your project's build path.
  4. Write JavaFX code to create and customize your application's user interface.
  5. Compile and run your JavaFX application.

Common Mistakes with JavaFX

  • Not properly configuring the JavaFX libraries in the project build path.
  • Not extending the Application class and implementing the start method correctly.
  • Not setting up the JavaFX application window with the correct layout and components.
  • Using incorrect JavaFX classes or methods for GUI manipulation.

Frequently Asked Questions (FAQs)

1. Is JavaFX still supported?

Yes, JavaFX is still supported and actively maintained by the Java community.

2. Can I use JavaFX with other Java frameworks or libraries?

Yes, JavaFX can be used alongside other Java frameworks and libraries to enhance your application's functionality.

3. Can I build mobile apps with JavaFX?

JavaFX is primarily designed for desktop applications. For mobile app development, you can consider using frameworks like JavaFXPorts or Gluon Mobile.

4. Can I style JavaFX applications?

Yes, JavaFX provides support for styling applications using CSS, allowing you to customize the appearance of UI components.

5. Can I use JavaFX with older versions of Java?

JavaFX was introduced in Java SE 7 and is officially bundled with Java SE starting from version 8.


JavaFX is a powerful framework for building modern, cross-platform graphical user interfaces in Java. It provides a wide range of features and components for creating visually appealing and interactive applications. By following the steps outlined in this tutorial, you can get started with JavaFX development and unleash the full potential of Java for GUI application development.
