Editing Factory method pattern (section)

==Overview==
The factory method design pattern solves problems such as:
* How can an object's [[Subclass (computer science)|subclasses]] redefine its subsequent and distinct implementation? The pattern involves creation of a factory method within the [[Superclass (computer science)|superclass]] that defers the object's creation to a subclass's factory method.
* How can an object's instantiation be deferred to a subclass? Create an object by calling a factory method instead of directly calling a constructor.

This enables the creation of subclasses that can change the way in which an object is created (for example, by redefining which class to instantiate).
