Abstract Factory

Difficulty-Intermediate Gang Of Four Java Creational

Also known as



Provide an interface for creating families of related or dependent objects without specifying their concrete classes.

alt text


Use the Abstract Factory pattern when

  • a system should be independent of how its products are created, composed and represented
  • a system should be configured with one of multiple families of products
  • a family of related product objects is designed to be used together, and you need to enforce this constraint
  • you want to provide a class library of products, and you want to reveal just their interfaces, not their implementations
