Node

javafx.scene.shape.Shape

javafx.scene.shape.Circle

public class Circle
extends Shape

The Circle class creates a new circle with the specified radius and center location measured in pixels.

Example usage. The following code creates a circle with radius of 50 pixels centered at (100,100).

import javafx.scene.shape.Circle;

Circle circle = new Circle();
circle.setCenterX(100.0f);
circle.setCenterY(100.0f);
circle.setRadius(50.0f);
