Changing location of shapes to a random location when mouse-clicked (javafx)

Question

I need exactly what the title says. I've made 10 circles with different radius sizes, now I just need to make them shift their locations when I click on the scene with the mouse. I tried finding the solution here but none of the questions contain exactly what I need. Here's my code:

Random random = new Random();

    int x = 0;
    int y = 0;
    int radius = 0;

    @Override
    public void start(Stage primaryStage) {

        Group root = new Group();

        for (int i = 0; i <= 10; i++) {

            Circle circle = new Circle(x, y, radius);
            {
                radius = random.nextInt(66) + 10;
                x = random.nextInt(600 - 2 * radius) + radius;
                y = random.nextInt(400 - 2 * radius) + radius;
            }
            circle.setFill(Color.BLACK);
            circle.setStroke(Color.BLUE);

            root.getChildren().add(circle);
        }
        Scene scene = new Scene(root, 800, 500, Color.BEIGE);
        Stage stage = new Stage();
        stage.setScene(scene);
        stage.show();
    }

Answer 1

translate x y with mouse event

Iterate through .getChildren().forEach() to get a child node of Group and translate it to random x y position . forEach() return a node object ,so it's not nescessary to cast it in this case

public class App extends Application {
    Random random = new Random();

    @Override
    public void start(Stage stage) {
          int x = 0;
    int y = 0;
    int radius = 0;
  
 Group root = new Group();
  
        for (int i = 0; i <= 10; i++) {
           

            Circle circle = new Circle(x, y, radius);
            {
                radius = random.nextInt(66) + 10;
                x = random.nextInt(600 - 2 * radius) + radius;
                y = random.nextInt(400 - 2 * radius) + radius;
            }
            circle.setFill(Color.BLACK);
            circle.setStroke(Color.BLUE);

            root.getChildren().add(circle);
        }
        Scene scene = new Scene(root, 800, 500, Color.BEIGE);
        
        scene.setOnMouseClicked(e->{
        
        root.getChildren().forEach((n) -> {
            n.setTranslateX(random.nextInt(0,800));
            n.setTranslateY(random.nextInt(0,500));
        });
        
        });
        
        stage.setScene(scene);
        stage.show();
    }

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

}
