Actually generic sevlet class is a super class of
HttpServlet class.both of these classes are abstract in
nature.As in generic servlet service () methob is not
defined so they r defined in HttpServlet class. as we are
not interested to create an object of HttpServlet class
so,we make it as abstract class and class that implemnts
HttpServlet Class creates objects and uses three methods
such as init(),service(),destroy() mainly.
