Polymorphism vs Method Overloading...
Method Overloading makes methods to be defined with different arguments with the same name... But when a method is called which has overloaded versions of methods, compiler will search for a particular method among the overloaded methods and finally select a method to be called during runtime.. that is method to be called is declared in compile time itself...
Polymorphism is not related to Method Overloading ... Polymorphism which allows same entity in different behaviors...
Even in the case of Method Overloading, when a new version of method is added, the client program should also be re-written to call that new version of program matching the arguments of newer version... So, Method Overloading does not lead to the ease of code maintenance....
