Singleton Design Pattern:
The singleton design pattern allows to have one and only one instance of an object to be created within the whole application. This can be achieved in java by making a Singleton class
Singleton pattern provides
-- access only to the unique instances,
-- permits a variable number of instances,
-- provides more flexibility than class operations.
-- it reduces name space, and
-- allows refinement of operations and representations,
-- It is used only at those places where the user requires only one instance of a class to be operating through out the application.
-- It is mostly used in the multi-threaded environments.
-- They often work as global variables permitting the allocation and initialization whenever required.
