Yes, it is irrelevant in this example. I'm guessing the kata is judged just by the structure of the function.

.. a new list with the strings filtered out

How does this leave room for returning a new list with newly created elements?

Also, how does F# get this wrong ?!?

Thanks, i will remeber it for future reference. Fixed

You can replace Rand rand = new Random() by ThreadLocalRandom rand = ThreadLocalRandom.current() and use this one. Also you can remove the import to java.util.Random then.

• Solution setup is missing the closing }
• The random values for r, o, w should be more concise.o can also be negative according to description. I suggest using the the ranges from JS: r in (0, 10), o in (-5, 8), w in (1, 10)
java.util.concurrent.ThreadLocalRandom has a method nextInt(lowerBound, upperBound).
