Should I override service() or doPost()?

Question

I was reading a book on servlets, in that book a brief explanation is given about the servlet class, as well as the HttpServlet class.

There is one exam

Answer 1

You most probably override the doXXX() method where XXX stands for the HTTP Methods like GET, POST, and so on. service() method invoked by the container will decide which of the doXXX() to be called.
