Filtering a list of numbers by a criterion is not a standard. It's a simple task. The discussion does have relevance - it shows why Java programmers need to rely so heavily on cookie cutter libraries: writing something from scratch is a huge bear. I routinely interview programmers of all kinds. Extremely few Java programmers ever make it because they simply don't know how to get simple (but non-mainstream) algorithmic tasks done.
