Diffrernce Between Overloading and Overriding?..

Answer / sourisengupta

OverLoading :- Method Name remains the same with different
signatures.
For ex:- Take a method name vehicle.
if u are passing two parameters to it , it will generate
informations for 2 wheelers .
if u are passing four parameters to it, it will generate
informations for 4 wheelers.

shortly we can tell same with different characteristics.

Overriding : - Method name and signatures must be same.
In overriding user can change the behaviour of the method
for the derived class.
