These are simple step by step code snippets to allow you learn JavaFX.

Example 1: Progressbar

Here are the code snippets:

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:

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

(a). ProgressBarExample.java

After creating our class, the first thing is to define imports. Such imports are ready made classes that inject more functionalities into our project.

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

The next step is to extend our class as shown below:

public class ProgressBarExample extends Application {

Our class will have the following methods:

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

For our Java program to run we need a main method. Add it as shown below:

    public static void main(String[] args) {

In this particular class we will be overriding our void start(Stage primaryStage) method.
Prepend the code>@Override</code modifier to your method. Then add implementation code as follows:

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("JavaFX App");

        ProgressBar progressBar = new ProgressBar(0);

        progressBar.setProgress(0.5);

        VBox vBox = new VBox(progressBar);
        Scene scene = new Scene(vBox, 960, 600);

        primaryStage.setScene(scene);
        primaryStage.show();
    }

Here is the full code:

package com.jenkov.javafx.progressbar;

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

public class ProgressBarExample extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("JavaFX App");

        ProgressBar progressBar = new ProgressBar(0);

        progressBar.setProgress(0.5);

        VBox vBox = new VBox(progressBar);
        Scene scene = new Scene(vBox, 960, 600);

        primaryStage.setScene(scene);
        primaryStage.show();
    }

}
