Method OverridingGiven below is the code for the Rectangle class.Define a new class named Square and override the methods area() and perimeter() to calculate the area and perimeter of a square.public class Rectangle { private double width; private double height; Rectangle(double width, double height){ this.width = width; this.height = height; } public double getWidth() { return width; } public double getHeight() { return height; } public void area() { System.out.println("Area of Rectangle is: " + (width * height) ) ; } public void perimeter() { System.out.println("Perimeter of Rectangle is: " + ( (2* width) + (2* height) ) ) ; }}

Consider the base class "Shape" with methods draw() [prints message "Draw"]. Create three subclasses: Circle, Square, and Triangle. Override the draw() method in each subclass to draw the respective shape, and override the calculateArea() method to calculate and return the area of each shape. Implement the above scenario with suitable pseudocode and appropiate java application.User Choice may be "C/S/T". a.)  C (Circle), then must read "Radius"b.)  S (Square), then must read "Side"c.)  T (Triange), then must read both "Height and Base".Identify the suitable data members for the above derived classes and ensure then all are private.

Create an abstract class named shape that contains two integers and an empty method named printarea().Provide three classes named rectangle, triangle and circle such that each one of the classes extends the class Shape. Each of the inherited class from shape class should provide the implementation for the method printarea(). Get the input and calculate the area of rectangle, circle and triangle.In the Main class, create the objects for the three inherited classes and invoke the methods and display the  area values of the different shapes.2(length of rectangle)3(breadth)5(triangle breadth)6(Triangle height)4(circle radius)

Create a class named ‘Shape’ which has methods ‘getArea’, ‘getPerimeter’and ‘getSide’.Make three subclasses for three different shapes - ‘Circle’, ‘Triangle’ and‘Rectangle’. These subclasses inherit the ‘Shape’ class and they have theirown ‘getArea’, ‘getPerimeter’, and ‘getSide’ methods definition.Each of these classes has its own data members likeThe circle will have a Radius,Triangle will have three sides,A rectangle will have width and heightWrite a program for the above scenario and display the solution.
