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 50px centered at (100,100)px.

import javafx.scene.shape.*;

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