Question about "getHeaderValue()"

[Malika Ben Aziz]

Hello folks
I am preparing for SCWCD using the book SCWCD EXAM STUDY KIT 2nd edition (SCE 310-081).

On the chapter about Servlets, 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?

hi malika

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.
