Creational Patterns

Two major responsibilities of Creational patterns are:
  • To encapsulate the concrete classes that system uses.
  • To encapsulate how instances of these classes are created.

Abstract Factory: Creates Instance from several family of related classes.

Builder: Separates object instantiation from object representation.

Prototype: A single object is copied and cloned.
