I am preparing for SCWCD using the book SCWCD EXAM STUDY KIT 2nd edition (SCE 310-081).
On the chapter about
, there is a response for a question that did not convince me.
7. Which of the following methods would you use to retrieve header values from a request? (Select two) a getHeader() of ServletRequest [b]b getHeaderValue() of ServletRequest //??? [/b]c getHeader() of HttpServletRequest d getHeaders() of ServletRequest e getHeaders() of HttpServletRequest Answers: b and e Explanation Headers are a feature of the HTTP protocol. Thus, all the header-specific methods belong to HttpServletRequest. getHeader() returns a String (or null), while getHeaders() returns an Enumeration of all the values for that header (or an empty Enumeration).
the explanation seems correct, but the answer is not.
I didn't find any thing about headers on the ServletRequest interface.
To me correct answer would be just "e"
Can you confirm please?

Yes you are right , the answer will be c and e
When you are in doubt then refer the specs and take them as the last say.
