If your servlet extends HttpServlet or GenericServlet, then it automatically gets a basic "init" method provided by the parent class.
If you have nothing ro do in "init", you don't need to bother writing one.

A servlet is not required to have a init() method.

According to Servlet specifications, each servlet should provide life cycle methods, so that container should be able to call them at appropriate time. The basic life-cycle methods are provided in Servlet interface. The GenericServlet class implements Servlet interface and HttpServlet class extends GenericServlet. You can implement Servlet interface, but that's not a good practice, as you will have to provide the implementation of all the methods. So we either extend GenericServlet or HttpServlet Class, depending upon the requirement, and thats why we need not to worry about init() and destroy() methods in case we don't want to do anything in init().
