Interfaces

Class	Description
AbstractFactory	AbstractFactory is used when we need to isolate the object creation with group of dependant objects
Builder	Builder is used when the constructor is complex or object creation has multiple steps
FactoryMethod	FactoryMethod will have individual factory method classes XMLMessageMessageFactoryMethod, JSONMessageMessageFactoryMethod for every instances needed XMLMessage, JSONMessage and we cannot go with SimpleFactory since the Message might be extended by different concrete classes in the future
ObjectPool	ObjectPool is used when the object creation is costly, so we have already created a pool of objects which can be reused
Prototype	Prototype will be used when the object creation is costly or not possible, so we implement Cloneable as well and clone the object
SimpleFactory	SimpleFactory is used to move the object creation in a separate method.
Singleton	Singleton is used when there should be only one instance of the that class
