How To Create Hello World Example In JavaFX

In this article, I will tell you what is JavaFX, and how to create the JavaFX hello world application example.

1. What Is JavaFX?

  1. JavaFX is a software platform for creating and delivering desktop and rich internet applications (RIAs) that can run on a variety of devices.
  2. It is a 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.
  3. JavaFX is built on top of the Java programming language and provides a rich set of libraries for building modern user interfaces, 2D and 3D graphics, animation, media playback, and more.
  4. JavaFX is widely used for developing desktop applications, mobile applications, and embedded systems.

2. How To Create JavaFX Hello World Application.

  1. To create a JavaFX application, follow these steps.
  2. Download and install JavaFX SDK: JavaFX is included in Oracle’s Java SE Development Kit (JDK) starting from Java SE 7 Update 6. You can download the latest JDK from the Oracle website.
  3. Set up your development environment: Once you have downloaded and installed the JavaFX SDK, you need to set up your development environment. You can use any Integrated Development Environment (IDE) that supports Java development, such as Eclipse, NetBeans, or IntelliJ IDEA.
  4. Create a new JavaFX project: In your IDE, create a new JavaFX project. This will create a basic JavaFX application with a main class that extends the javafx.application.Application class.
  5. Design the User Interface: Use FXML, which is a markup language that allows you to define a user interface declaratively, or programmatically create the user interface using Java code.
  6. Add Functionality: Add functionality to your application by writing code that responds to user input and interacts with data sources.
  7. Build and Run the Application: Once you have designed the user interface and added functionality to your application, you can build and run it from within your IDE.
  8. Here is a simple example of a 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 HelloWorld extends Application {
        
        @Override
        public void start(Stage primaryStage) {
            Label label = new Label("Hello, World!");
            StackPane root = new StackPane();
            root.getChildren().add(label);
            Scene scene = new Scene(root, 300, 200);
            primaryStage.setTitle("Hello World");
            primaryStage.setScene(scene);
            primaryStage.show();
        }
        public static void main(String[] args) {
            launch(args);
        }
    }
  9. This code creates a simple JavaFX application that displays a label that says “Hello, World!” in the center of the screen.

3. How To Download JavaFX SDK Using Maven.

  1. To download JavaFX SDK using Maven, follow these steps.
  2. Add the following Maven dependency to your project’s pom.xml file, this will download the JavaFX controls module version 16.
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-controls</artifactId>
        <version>16</version>
    </dependency>
  3. If you need other JavaFX modules, add them to the dependencies list in the same way, changing the artifactId and version accordingly.
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-fxml</artifactId>
        <version>16</version>
    </dependency>
  4. Make sure that your project is configured to use Java version 11 or later, as JavaFX is not included in Java SE starting from Java 11.
  5. Run mvn clean install or mvn package to build your project and resolve the dependencies.
  6. Configure your build tool to include the JavaFX SDK libraries in the classpath when running your application. This can be done by adding the following plugin configuration to your pom.xml file:
    <build>
        <plugins>
            <plugin>
                <groupId>org.openjfx</groupId>
                <artifactId>javafx-maven-plugin</artifactId>
                <version>0.0.7</version>
                <configuration>
                    <mainClass>com.example.Main</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>
  7. This plugin will create a runnable JAR file that includes the JavaFX SDK libraries and your application code.
  8. Run your JavaFX application using the following command:
    java -jar target/myapp.jar
  9. Replace myapp.jar with the name of your generated JAR file.
