[Shobhan Ganta]

For a given ServletResponse response, which two retrieve an object for writing text data?
(Choose two.)
A. response.getWriter()
B. response.getOutputStream()
C. response.getOutputWriter()
D. response.getWriter().getOutputStream()
E. response.getWriter(Writer.OUTPUT_TEXT)

Answer: A, B

Shouldn't it be just A?

Thanks

No, it has to be both A and B, with the getOutputStream() you get an object of ServletOutputStream which could be used to write text data by chaining a say, DataOutputStream about it.

Furthermore, the getWriter() gives you a PrintWriter object which is chained to this ServletOutputStream behind the scenes. So, in the end its just the ServletOutputStream that is used to write data( byte/text).
