Which of the following methods can be used to receive a file sent by a browser?

Why the answer "getInputStream() of HttpServletRequest" is wrong?

We can get access to this method, because HttpServletRequest extends ServletRequest.
If HttpServletRequest extends ServletRequest and ServletRequest has getInputStream(), then HttpServletRequest has getInputStream().
Am I wrong?

You are right but in a question like this where a method and its exact class/interface name is given, you should select the one in which that method is declared.

Such kind of questions are confusing, but I'll be ready for them. Thank you
