the very first step of creating the servlet is making its
object after until and unless you will not trigger the init
method it will be treated as simple object not the servlet
after triggering the init method it get the servlet config
init parameters and then only it is called as servlet so its
very imp to intiate the init method

Answer / abhijit mishra
As per Servlet specification, the servlet container is
responsible for creating the servlet and initializing it( or
making it ready for client to request it).
So according to the Client:servlet container contract, the
servlet creation and inialization is done by the container
which will differ for different container provider.
So u can't use constructors to create servlets.

Answer / manas banerjee
you can use but should not.the original reason for init()
was that ancient version of java could not dynamically
invoke constructors with arguments.so there was no way to
give the constructors a ServletConfig.So u would not have
to access to ServletConfig or ServletContext.
{{in short:init() has access to servletconfig and
servletcontext object constructor would not..

Answer / archana
When u create a servlet with a constructor it wont be a
complete servlet but will be in a akward state where it
cannot access Servlet Context and Config.It has to go
through the init() method (though we dont know what code is
written there) to be a complete servlet
