I would say no... Extending is adding functionality, whereas overloading is
changing functionality (or specifically methods). For instance, A person has
a ssNo. An employee has a ssNo and an employee number, thus giving MORE
functionality, but allowing the users to make use of previous functionality.
This is however, an OO discussion and not servlets...
