Setting up the JavaFX project(Gradle based)
  1. Go to File-> New-> Project and click.One popup dialog will appear.
  2. On left panel of dialog, click on gradle.
  3. On right panel you will see some check boxes. Select Java and click Next.
  4. You will asked to fill some text fields.
  5. Enter project's package name in GroupId(i.e com.coderzduniya.fxdemo).
  6. Enter project name in ArtifactId(i.e JavaFX Demo).
  7. Leave Version as it is and go to Next.
  8. Go to Next again and Finish.
  9. After doing it well your project will be created.
  • Now right click on java folder inside src/main and go to New-> JavaFXApplication

 //Base Container
        final GridPane root = new GridPane();

        //Positioning contents
        root.setHgap(15);
        root.setVgap(15);
        root.setAlignment(Pos.CENTER);

        //Creating User name fields
        final Label labelUserName = new Label("UserName:");
        final TextField tfUserName = new TextField();

        //Creating password fields
        final Label labelPassword = new Label("Password:");
        final TextField tfPassword = new TextField();

        //Creating button
        final Button btnOK = new Button("Click Me");
        btnOK.setAlignment(Pos.BOTTOM_RIGHT);

        //Adding contents to the root
        root.add(labelUserName, 0, 0);
        root.add(tfUserName, 1, 0);
        root.add(labelPassword, 0, 1);
        root.add(tfPassword, 1, 1);
        root.add(btnOK, 1, 3);

        //Creating a window on which root will be displayed with provided width and height
        final Scene scene = new Scene(root, 400, 300);

        //Set scene to the stage
        primaryStage.setScene(scene);

        //Set app title
        primaryStage.setTitle("JavaFX Demo");

        //Show/Launch the app
        primaryStage.show();

        //Adding click listener to button
        btnOK.setOnAction(event -> System.out.println("Button clicked!"));


This is a basic example of JavaFX. Hope this will be helpful to you.
