Explain the Intersect operation on 2D shapes in JavaFX

This operation takes two or more shapes as inputs and returns the intersection area between them as shown below.

The intersect() (static) method of the javafx.scene.shape.Shape class accepts two Shape objects and returns the result of the intersect operation of the given objects.

Example

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.scene.shape.Circle;
import javafx.scene.shape.Shape;
public class JavaFXIntersectExample extends Application {
   public void start(Stage stage) {
      //Drawing circle1
      Circle circle1 = new Circle();
      circle1.setCenterX(230.0f);
      circle1.setCenterY(100.0f);
      circle1.setRadius(75.0f);
      circle1.setFill(Color.DARKRED);
      //Drawing Circle2
      Circle circle2 = new Circle();
      circle2.setCenterX(280.0f);
      circle2.setCenterY(170.0f);
      circle2.setRadius(75.0f);
      circle2.setFill(Color.DARKRED);
      //Drawing Circle3
      Circle circle3 = new Circle();
      circle3.setCenterX(330.0f);
      circle3.setCenterY(100.0f);
      circle3.setRadius(75.0f);
      circle3.setFill(Color.DARKRED);
      //Intersect Operation
      Shape intersect = Shape.intersect(circle1, circle2);
      intersect = Shape.intersect(intersect, circle3);
      intersect.setFill(Color.RED);
      //Setting the stage
      Group root = new Group(circle1, circle2, circle3, intersect);
      Scene scene = new Scene(root, 595, 300);
      stage.setTitle("Intersect Operation");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
