If the question is "Which methods are used by a servlet to handle form data from a client?", is HttpServlet.doPost() is the only correct answer?

Is HttpServlet.doGet() a correct answer as well? Any other methods we can add as a correct answer?

This is question 8 on page 146 of HFSJ 2nd edition.

Thanks in advance.

The (X)HTML specifications allow both POST and GET as submission methods for forms. Usually it's the former though because of the amount of data to be transferred, and the limitations on the length of a URL (using GET). Often the form will POST, and then the client will be HTTP-redirected using GET to avoid problems with the back button and form re-submission.
