When to use Method overloading or method overriding

Vivek Bansod

What is real time scenario where we must have to use Method overloading or method overriding and no other option? I mean when it is recommended to use these concepts of Polymorphism?

Hi
Overloading:
int Area( int len, int height) // Area of rectangle
Ex: Let suppose you want to calculate area of all geometry like square, rectangle, square etc.
Here method name is same for all geometry but signatures are different.

Overriding:
Let suppose you want o use same method every where but only method
definition will be different.
Ex: Result();
Here result is common method which will be implemented by all class with different definitions.
Result will display different value for different classes.

Best example is ToString method .

You can override the same according to your need.

Thanks Nishant & Rajeesh,

I got it conceptually but looking for a strong scenario where we have to use overloading or overriding. Overlaoding is simple for that matter but desparately looking for overriding scenario

Hi Vivek

When you want to provide your defination to the existing method, then you have to use Overriding and when you have to use same functionality with different no. of parameters you have to go for Overloading..
