Difference between Function and Method



  • Function do not have any reference variables.

  • All data that is passed to a function is explicitly  passed.

  • It does not have access controlling i.e. Function(other than static functions) declares and defines anywhere in the code.

  • Function applies to both object oriented and non-object oriented language(procedural language eg: C, Scripting language eg: Python, JavaScript etc) 

  • Function have independent existance means they can be defined outside of the class.

  • Function are called independently.


  • Method are called by reference variables.

  • It is implicitly passed the object for which it was called.

  • It has access controlling i.e. Method should declare and define in the class only.

  • Method is only applicable to object oriented programming language like C++, C#, Java etc.

  • Method do not have independent existance they are always defined with in class.

  • Method are called using instance or object.
