Refined Abstraction:?

• The Circle class is a refined abstraction that extends the Shape class and

provides the implementation for the Draw() method. It uses the passed

IDrawingAPI to draw the circle.

public class Circle : Shape
{
private double _x, _y, _radius;
public Circle(double x, double y, double radius, IDrawingAPI

drawingAPI)

: base(drawingAPI)

{
_x = x;
_y = y;
_radius = radius;
}
public override void Draw() => _drawingAPI.DrawCircle(_x, _y,

_radius);

}
