what's the difference between Method and Function calls?

Answer 1

The main difference between a function and a method in any OO language is that, a method is always called using the object of that class in which the method is written. Say for example Class A contains Method B . . to call Method B you require the object of Class A. 

While function are those which you can call without creating objects.
