Design a class called circle which contains: -Two instance variables: radius (type double) and color (type String), default value of 1.0 and "red". -Two overloaded constructors - a default constructor with no argument, and a constructor which takes a double argument for radius. -Two methods: printRadius() and Area(), which print the radius and return the area of this instance, respectively.

We have to calculate the area of a rectangle, a square and a circle. Create an abstract class 'Shape' with three abstract methods namely 'RectangleArea' taking two parameters, 'SquareArea' and 'CircleArea' taking one parameter each. The parameters of 'RectangleArea' are its length and breadth, that of 'SquareArea' is its side and that of 'CircleArea' is its radius. Now create another class 'Area' containing all the three methods 'RectangleArea', 'SquareArea' and 'CircleArea' for printing the area of rectangle, square and circle respectively. Create an object of class 'Area' and call all the three methods.
