Shape Class

Create a superclass called Shape with an instance method Displaylnfo that will return a string

containing the name, area and perimeter of the shape.

public String DisplayInfo$()\{$

The superclass has the following instance variables: ShapeName $($String$),$ Area $($double$)$ and

Perimeter$($double$).$ Also create an instance methods setArea and setPerimeter.

Create a subclass of Shape called Circle witi an instance variable radius $($private double$)$ and

create a constructor for this subclass. Also create the following instance methods: Area $($method

that will return the area of a circle$),$ Perimeter $($method that will return the perimeter of a

circle$),$ and the set and get for the instance variable.

Create another subclass of Shape called Rectangle with instance variables $($private length and

private width$)$ and create a constructor for this subclass. Also create the following instance

methods: Area $($method that will return the area of a rectangle$),$ Perimeter $($method that will

return the perimeter of a rectangle$)$ the set and get for the instance variables.

Create a class ShapeTest that will demonstrate polymorphism. Create at least two objects to test

the two subclasses. Ask for the keyboard input from the user for the needed values to compute

the Area and Perimeter for both Circle and Rectangle.
