Isn't it all just StreamUtils.copy(System.in, System.out) I'm pretty sure there is a function that just copies an input stream to an output stream in commons-lang. Still I agree with him - I won't write Java in a test like that. It is almost impossible to write Java fast without an IDE to autocomplete everything for you. There are way too many names to remember. I can't even tell you what package StreamUtils are in or if it's StreamUtils or FileUtils.
