Private constructor is simple constructor that has private
access modifier.
Private constructors are used for two purposes.
1)to prevent creation of objects outside the class when
there are no instance variables in the class and the
methods of class takes some input parameters and does
processing and returns the result without getting or
setting instance variables like in math class of .NET.
2)When your application requires a class that has only one
instance and you need to provide a global point to access
that instance like in the case of singleton.
