Only one class is being extended. HttpServlet.
Servlet is an interface.
You may only extend ONE class. You may implement as many interfaces as you like (there is probably some limit but not worth worrying about).
What I means why ultimate interface and immediate super class implements and extends in same class. I.e. Servlet is interface it has
Init()
getServletConfig()
service()
getServletInfo()
destroy()
above all abstract methods all are implemented in HttpServlet. Why once again implements the interface in this class. We simply extend the HttpServlet class. What抯 the need?
