COMP 328 Polymorphism

Implement the Shape hierarchy shown in the figure below. Each TwoDimen¬sionalShape should contain method getArea to calculate the area of the two-dimensional shape.

Each ThreeDimensionalShape should have methods getArea and getVolume to calculate the surface area and volume, respectively, of the three-dimensional shape.

Create a program that uses an array of Shape referenc¬es to objects of each concrete class in the hierarchy.

The program should print the object to which each array element refers. Also, in the loop that processes all the shapes in the array, determine whether each shape is a TwoDimensionalShape or a ThreeDimensionalShape. If a shape is a TwoDimensionalShape, display its area. If a shape is a ThreeDimensionalShape, display its area and volume. See image.
