Implement the Shape hierarchy shown in Fig. 1. Each TwoDimensionalShape should contain method getArea to calculate the area of the two-dimensional shape. Each Three DimensionalShape
Implement the Shape hierarchy shown in Fig. 1. Each TwoDimensionalShape should contain method getArea to calculate the area of the two-dimensional shape. Each Three DimensionalShape 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 references to objects of each concrete class in the hierarchy. The program should print a text description of 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 Two DimensionalShape or a Three DimensionalShape. If a shape is a Two DimensionalShape, display its area. If a shape is a Three DimensionalShape, display its area and volume. In your design you must define the class Shape is an abstract class. Your output should appear as follows: Circle: [22, 88) radius: 4 Circle's area is 50 Square: [71, 96) side: 10 Square's area is 100 Sphere: [8, 89) radius: 2 Sphere's area is 50 Sphere's volume is 33 Cube: [79, 61) side: 8 Cube's area is 384 Cube's volume is 512 Your output should appear as follows: Circle: (22, 88) radius: 4 Circle's area is 50 Square: [71, 96) side: 10 Square's area is 100 Sphere: [8, 89) radius: 2 Sphere's area is 50 Sphere's volume is 33 Cube: [79, 61) side: 8 Cube's area is 384 Cube's volume is 512 Shape TwoDimensionalShape Three DimensionalShape Circle Square Triangle Tetrahedron Sphere Cube Figure 1: Inheritance hierarchy UML class diagram for Shapes
