/*
Create the following class AreaOfCircle which has Attributes – Radius, area, perimeter and
Methods - getRadius(), findArea(), findPerimeter(). getRadius() should get user input as radius.
findArea() returns area of the circle. findPerimeter() returns perimeter of the circle. Create 2
objects and compare the areas of the objects.
