Overriding Methods

Next, override one or more methods to provide the servlet with instructions to perform its intended task. All processing by a servlet is done on a request-by-request basis and happens in the service methods, either service() for generic servlets or one of the doOperation() methods for HTTP servlets. This method accepts requests processes them according to the instructions you provide, and directs the output appropriately. You can create other methods in a servlet as well.
