# Abstract Factory

* Provide an interface for creating families of related or dependent objects without specifying their concrete classes.
* An Abstract Factory creates objects that are related by a common theme. In object-oriented programming a Factory is an object that creates other objects. An Abstract Factory has abstracted out a theme which is shared by the newly created objects.
