public class Ex05 extends Application {
    
    @Override
    public void start(Stage primaryStage) {
        
        Circle circ = new Circle(
                200, 200,   // center x,y
                100,        // radius
                Color.RED); // fill

        Group root = new Group();
        root.getChildren().add(circ);
        
        Scene scene = new Scene(root, 400, 400, Color.AQUA);
        
        primaryStage.setTitle("Example 5. Circle");
        primaryStage.setScene(scene);
