Creational Design Pattern

It deals with object creation mechanism , create object suitable to situation. 

This pattern is further divided into two parts 
1. Class creational patterns 
2. Object creational patterns.

 Class creational deals with class creation and Object creational deals with object instantiation.  

In greater details, 

Object-creational patterns defer part of its object creation to another object, while Class-creational patterns defer its object creation to subclasses. i.e. class-creation patterns use inheritance effectively in the instantiation process, object-creation patterns use delegation effectively to get the job done.

Following are the creational design pattern:-

1.Singleton

2.Abstract Factory

3.Builder

4.Factory Method

5.Object Pool

6.Prototype

7. Lazy initialization
