Overriding Methods

Override one or more methods to provide servlet instructions to perform its intended task. A servlet does all the processing on a request-by-request basis and happens in the service methods, either service() for generic servlets or one of the do Operation() methods for HTTP servlets. This method accepts incoming requests, processes them according to the instructions you provide, and directs the output appropriately. You can create other methods in a servlet as well.
