In this tutorial we will learn more JavaFX widgets usage via simple examples.

Example 1: Label

Let us look at the code

Step 1: Create Project

  1. Open your favorite Java IDE.
  2. In the menu go to File --> Create New Project.

Step 2: Dependencies

No dependencies are needed for this project.

Step 3: Write Code

Our code will comprise the following java files:

  • LabelChangeTextExample.java
  • LabelExample.java
  • LabelFontExample.java
  1. In your editor or IDE, create a file known as LabelChangeTextExample.java.
  2. Then add the following code:

(a). LabelChangeTextExample.java

Like in every program we write, we will need to import functionalities into our project. Add the following imports:

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

Extend the class as shown below:

public class LabelChangeTextExample extends Application {

Our class will have the following methods:

  • void main(String[] args)
  • void start(Stage primaryStage)

Let's create a main method as shown below:

    public static void main(String[] args) {

Here is the full code:

package com.jenkov.javafx.label;

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

public class LabelChangeTextExample extends Application {

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

    public void start(Stage primaryStage) {

        Label label = new Label("Initial Label Text");

        label.setText("New Label Text");

        VBox vBox = new VBox(label);
        Scene scene = new Scene(vBox);

        primaryStage.setScene(scene);
        primaryStage.setTitle("JavaFX App");

        primaryStage.show();
    }
}
  1. Next create another file known as LabelExample.java.
  2. And add the following code:

(b). LabelExample.java

Like in every program we write, we will need to import functionalities into our project. Add the following imports:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;

Extend the class as shown below:

public class LabelExample extends Application {

Our class will have the following methods:

  • void main(String[] args)
  • void start(Stage primaryStage)

Let's create a main method as shown below:

    public static void main(String[] args) {

Here is the full code:

package com.jenkov.javafx.label;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;

public class LabelExample extends Application {

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

    public void start(Stage primaryStage) {

        Label label = new Label("Label Text");

        VBox vBox = new VBox(label);
        Scene scene = new Scene(vBox);

        primaryStage.setScene(scene);
        primaryStage.setTitle("JavaFX App");

        primaryStage.show();
    }
}
  1. Next create another file known as LabelFontExample.java.
  2. And add the following code:

(c). LabelFontExample.java

Like in every program we write, we will need to import functionalities into our project. Add the following imports:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;

Extend the class as shown below:

public class LabelFontExample extends Application {

Our class will have the following methods:

  • void main(String[] args)
  • void start(Stage primaryStage)

Let's create a main method as shown below:

    public static void main(String[] args) {

Here is the full code:

package com.jenkov.javafx.label;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;

public class LabelFontExample extends Application {

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

    public void start(Stage primaryStage) {

        Label label = new Label("A label with custom font set.");

        label.setFont(new Font("Arial", 24));

        VBox vBox = new VBox(label);
        Scene scene = new Scene(vBox);

        primaryStage.setScene(scene);
        primaryStage.setTitle("JavaFX App");

        primaryStage.show();
    }
}
