Creational patterns deals with object creation process. In object oriented software development, while designing and implementation, designers and coders work with classes and objects. Different types of problems might require different object interactions to solve a particular problem. Creating objects as per the problem requirements is an important design issue. The creational patterns deal with this issue and help the designers to solve and guide the object creation mechanisms.
Creational design patterns are further classified into: class-creational patterns and object-creational patterns. Class-creational patterns deals with instantiation of a subclass based on the context. Object-creational patterns deals with delegation of object creation process to another object.
There are five creational patterns:
1) Abstract Factory
3) Factory Method
