Develop program which reference objects of each concrete, Ask an Expert

Programming

Each TwoDimensionalShape must contain method getArea to compute area of two-dimensional shape. Each ThreeDimensionalShape must have methods getArea and getVolume to compute surface area and volume, respectively, of three-dimensional shape. Develop program which reference objects of each concrete (non-abstract) class in hierarchy. Write down abstract method "display" which determines whether displayed shape is TwoDimensionalShape or ThreeDimensionalShape. If shape is TwoDimensionalShape, show its area. If shape is ThreeDimensionalShape, show its area and volume.
