When to use Method Overriding & Method Hiding using real time example

When to Use:

When we want different implementation in all derived classes and base class with default implementation, so if any derived class does not have there own implementation then default base class method will be called.

namespace OverridingExample

{

   //Base Class

   class Shape

    {

        //Method to be overridden in derive class

        public virtual void CalculateArea()

        {

               //Default Implemention.

            Console.WriteLine(" Default Area Calculated.");

        }

    }

    

    //Child Class

    class Circle: Shape

    {

        public override void CalculateArea()

        {

            Console.WriteLine("Circle Area Calculated.");

        }

    }

    

   class Rectangle: Shape

    {

        public override void CalculateArea()

        {

            Console.WriteLine("Rectangle Area Calculated");

        }

    }

   

   //Class Square does not override method CalculateaArea

    class Square : Shape

    {

        

    }

    class Program

    {

        static void Main(string[] args)

        {

           // Creating Object of circle class

            Shape shape1 = new Circle(); 

            shape1. CalculateArea();

            // Creating Object of rectangle class

            Shape shape2 = new Ractangel();

            shape2. CalculateArea();

            // Creating Object of Square class -> Square class does not have override method, so it will take default                     implementation of Base class

            Shape shape3 = new Square();

            shape3.CalculateArea();

            Console.ReadLine();

        }

    }
