What is Singleton Class: How will you make a class singloton....
----------------------------------------------------------------------

Singleton class:
This is a class which can be instatiated only once.

Eg:

Public class Singleton
{
private static single = new Singleton();

Private Singleton();
{}
}


For a singleton class, the constructor is made private and
a static variable is used for instatiating the class.
