Flyweight Pattern

A Flyweight Pattern says that just "to reuse already existing similar kind of objects by storing them and create new object when no matching object is found".

Advantage of Flyweight Pattern

• It reduces the amount of memory and storage devices required if the objects are persisted

Usage of Flyweight Pattern

• When an application uses number of objects
• When the storage cost is high because of the quantity of objects.
• When the application does not depend on object identity.
