Answer 1

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.

Answer 5

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..
