Flyweight Design Pattern. ; Behavioral: This type of design patterns provide solution for the better interaction between objects, how to provide lose coupling, and flexibility to extend easily in future. Flyweight is used when there is a need to create high number of objects of almost similar nature. The Decorator Pattern comes under the Structural pattern.
