Why not? We can override these two methods also. We can override init() method for connecting to the database or some other resources. The init() method called by the container only once ,when the servlet has been loaded into the memory. You can override the destroy method to release the resources. When we stopped our server the destroy method will call by the container. But the service method will call each and every time the request came.

bcz init() and destroy() methods can call only once in the life-cycle of a servlet due to which we can make only one object during the session , thats why it is better than CGI bcz in that we have to call init() method every time when we request the servlet

Int() and destroy() methods are override in servlet class surly 100% no problum
but int() is not a life cycle method .it is a convenenance method Here we write initilising logics like conncetion obj and statement objects

and destroy() are also one time execution block when programmer raising an event i.e shut down server like that

Code
abstract class Generic servley


{


public void inti(ServletConfig cg)


{


----------------------------


-----------------------


init()


------------------------


--------------------


}


servletconfig getServletConfig()


{


return cg;


}


destroy()


{


--------------


}


class Hello extends GenericServlet


{


init()


{


---------------------------------


--------------------------------//logic to write con,st objects


--------------------------------


}


public void destroy()


{


------------------------------// logic to write release the resources


--------------------------


}

init() is possible to override () if you have initialization code like database connection or registering your self.
service() method look the request and response. Determine the Http method (get,post). Override not possible

Can override init & destroy .
People used to make mistakes by overriding inti(ServletConfig).
Because if we override and forget to call super.inti(ServletConfig) then default actions doesn’t get performed. As a result getServletConfig() will return null.
