What is the need of implicit objects?

They are used to manipulate the requests, responses and sessions:Implicit objects in jsp are the objects that are created by the container automatically and the container makes them available to the developers, the developer do not need to create them explicitly.:Implicit objects let developers access container-provided services and resources. These objects are defined as implicit because you do not have to explicitly declare them. They are defined in every JSP page and used behind the scenes by the container whether you declare them or not -- although you cannot redeclare them. Because implicit objects are declared automatically, we need only use the reference variable associated with a given object to begin calling methods on it.Functional categories of implicit objects: * Session management: application, session, request, pageContext * Flow control: application, config, pageContext, request, session * Logging and exceptions: application, config, exception, pageContext, request, session * Input/output control: request, response, out * Initialization parameters: config
