/*
 * 1. static variable is always associated with data member of a class and not with local variable of method 
 * Hence if we create/declare static variable in in static or non-static method it will give an error
 * 
 * 2. static method can access only static members 
 * 	  Kite.staticMethod()
 *    how it could identify which obj is calling method, so not non-static members
 * 
 * 3. static var --> single copy only/ created only once 
 *    ex. aadharNo, DOB
