Ans: This is a fact based interview question what it checks is how much coding you do in JSP if you are doing it frequently you definitely know them. Implicit object is the object that is created by web container provides to a developer to access them in their program using JavaBeans and Servlets. These objects are called implicit objects because they are automatically instantiated.they are bydefault available in JSP page.

They are request, response, pageContext, session, and application, out, config, page, and exception.
