method
subject			fact

method	has definition A concrete implementation of an operation; a procedure in a class
	is equivalent to the terms "function member" or "member function" which are used in C++
	is equivalent to the terms "routine", "function" or "procedure" which are used in non object oriented languages
	is a subtopic of 2.4 - Methods, Operations and Polymorphism
	is a kind of procedural abstraction
	is a kind of procedure
	should have a comment at its head if the method is non-obvious
procedural abstraction	has advantage when using a certain procedure, a programmer does not need to worry about all the details of how it performs its computations; he or she only needs to know how to call it and what it computes
	hides the details of procedures
procedure	provides procedural abstraction

Kinds of method :

• abstract method (1 kind, 3 facts)
• class method (1 kind, 6 facts) (static method) - A method that, unlike an instance method, does not execute in the context of a particular instance of a class
• hook method (3 facts) - A method that does nothing other than returning to its caller, but is designed to be overridden in subclasses
• instance method (1 kind, 3 facts) - A method that executes in the context of a particular object; it has access to the instance variables of the given object, and can refer to the object itself using the 'this' keyword (in Java and C++)
• Java method (12 kinds, 8 facts)
• long method (5 facts)
• utility (6 facts) - A method or class that has wide applicability to many different subsystems and is designed to be reusable
