Shape Main Class

Use the main class for testing. You won't be graded on your main class other than it must exist.

Shape Class

Build the Shape class with the following specifications:

Must be abstract

Public abstract getArea()

Square Class

Build the Square class with the following specifications:

Subclass of Shape

Public setSide()

Public getSide()

Implements getArea() correctly

Ex: Using setSide(5) results in getArea() return 10. Area = side*side

Circle Class

Build the Circle class with the following specifications:

Subclass of Shape

Public setRadius()

Public getRadius()

Implements getArea() correctly

Ex: Using setRadius(5) results in getArea() return 10. Area = PI*(R^2). Hint use Math.PI
