In Java,

Implement the Shape hierarchy in Fig. 1.

1. Shape needs to be implemented as an abstract class.

2. Each Two Dimensional Shape should contains method getArea() to calculate the area of the two-dimensional shape.

3. Each Three Dimensional Shape should contains method getArea() and getVolume() to calculate the surface area and volume, respectively, of the three-dimensional shape.

4. Create a program that uses an array of Shape references to objects of each concrete class in the hierarchy.

Print a text description of the object to which each array element refers.

All the shapes in the array are needed to be processed

determine whether a shape is a TwoDimensionalShape or a ThreeDimensionalShape

if it is a TwoDimensionalShape, display its area;

if it is a TwoDimensionalShape, display its area and volumn.

Thank you in advance!
