What is the Servlet Interface?

The central abstraction in the Servlet API is the Servlet interface. All servlets implement this interface, either directly or, more commonly, by extending a class that implements it such as HttpServlet.Servlets-->Generic Servlet-->HttpServlet-->MyServlet.The Servlet interface declares, but does not implement, methods that manage the servlet and its communications with clients. Servlet writers provide some or all of these methods when developing a servlet.

while writing servlet this the interface you must implement either directly or indirectly by extending either javax.servlet.GenericServlet or javax.servlet.http.HttpServlet class.

This is the interface web-container use to reference servlets, it contains all the life cycle methods of a servlet.

It is nothing but an interface which contains set of method names (prototypes).
Those are called servlet life cycle methods.
init(ServletConfig)
getServletConfig()
service(SeveletRequest , ServletResponce)
distroy()

The class whch says itself a servlet class, must implement these methods first (directly or indirectly). These methods will be called by the web container at different states of the life cycle of servlet object ...
