Abstract Factory Pattern<\/strong>
\nThe Abstract Factory Pattern consists of an AbstractFactory, ConcreteFactory, AbstractProduct, ConcreteProduct and Client. We code against AbstractFactory and AbstractProduct and let the implementation to others to define ConcreteFactory and ConcreteProduct<\/p>\n

Why Abstract Factory Introduced?<\/strong>
\nAnother layer of abstraction over factory pattern. Abstract Factory patterns work around a super-factory which creates other factories. Factory pattern deals with creating objects of a single type(AppleFactory manufactures Iphones), while the Abstract Factory pattern deals with creating objects of related types(MobileFactory manufactures Mobiles). Abstract Factory pattern is more robust and consistent and uses composition to delegate responsibility of object creation. <\/p>\n

When to use Abstract Factory?<\/strong>
\nWhen higher level of Abstraction is required.Provides an interface for creating families of related objects<\/p>\n
