Answer / vivekanand prasad
The init() method creates and loads the servlet.But the servlet instance is first created through the constructor (done by Servlet container). We cannot write constructors of a servlet class with arguments in servlet (It will throw Exception). So, They provided a init() method that accepts an ServletConfig object as an argument.ServletConfig object supplies a servlet with information about its initialization (init) parameters.Servlet class cannot declare a constructor with ServletConfig object as a argument and cannot access ServletConfig object.

Answer / qim2010
One can definitely have constructor in servlet. Even you can
use the constructor in servlet for initialization purpose,
but this type of approach is not so common. You can perform
common operations with the constructor as you normally do.
The only thing is that you cannot call that constructor
explicitly by the new keyword as we normally do. In the case
of servlet, servlet container is responsible for
instantiating the servlet, so the constructor is also called
by servlet container only.
