it is java, so yeah. of course production code could have all sorts of levels of tests and qa and all that jazz.

really, though, if i'm implementing an algorithm that i've never coded before it would seem strange not to write at least some kind of verification of its correctness.

comments can be language dependent - perl yes, java maybe (on an API, definitely) - and situation dependent. i wouldn't care about comments on small amounts of code with good variable names and sensible structure, for example.

edit : also apologies for the formatting, i hate typing on a phone!
