Implement the Shape hierarchy shown in Figure below. Each TwoDimensionalShape 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 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 TwoDimensionalShape or a ThreeDimensionalShape. If it’s a TwoDimensionalShape, display its area. If it’s a ThreeDimensionalShape, display its area and volume.

Instructions

1) Implement the Shape hierarchy shown above.

  • Each TwoDimensionalShape should contain the 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.

2) 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 TwoDimensionalShape or a ThreeDimensionalShape.

  • If it's a TwoDimensionalShape, display its area. If it's a ThreeDimensionalShape, display its area and volume.
