Method called during servlet initialization

[P. Jain]

I am studying from 2 books i.e Head first Servlets and Jsp and SCWCD Kit by Hanumant Deshmukh.

My problem is that one book says that init(servletconfig) is called during initialization and other book says that init() method is called.

I just want to confirm which method is called?

Both the methods are called during servlet initialization only.

init(servletConfig) is called first.
init() is called from within init(servletConfig).
We can override init() for putting our own servlet initialization code.

The servlet container can't call init(), because it is not part of the Servlet interface. init() is a method of GenericServlet, so it doesn't necessarily exist (because you're free to create servlets that do not extend GenericServlet or its subclass HttpServlet).

This kind of information is generally -and specifically in this case- part of the javadocs.

Thanks for the reply. My doubt has been cleared.
