Here is my take on it :
I wouldn't go so far as to call it "good" but it has multiple things going on for it, like :

- No explicit imports, so it's "pure" Java actually
- No conditions, only one loop
- No fancy FP stuff
- No "FizzBuzz" special case, "Fizz" or "Buzz" only
But of course you have to decipher the 2d array, recognize "^$" as an empty string regex, pass over some redundancies ...
