Question

Implement the Shape hierarchy shown in Fig. 9. 3 in the text. Each Two Dimensional Shape should contain methods getArea and getPerimeter to calculate the area and perimeter of the two-dimensional shape. Each three Dimensional Shape 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 and perimeter. If it's a ThreeDimensionalShape, display its area and volume. The 3 top level classes should be abstract and should have at least one abstract method. You can instantiate a triangle object with 5 data points: base, height, and the length of each of the three sides. This needs to be coded in JAVA. Please also show output and explain how you did with comments.
