/**

* Here we described creating singleton using enum but why?

* Let's say in Lazy Init method you access constructor by reflection (Reason being you can access private constructor using reflection!!)

* and create the object which eventually creates the problem by having multiple instances.

*

* ENUM's constructor gets invoked by JVM not by User who is using so it is safe to use.

* Another advantage of using enum is , we don't need to worry about threads as it is thread safe.

* It also solved the problem of Serialization as JVM takes care to return same object.
