Language-specific output example in description is missing for Java.

There's no mention of ships being discontinuous in the description and this isn't part of the actual game so such a note could be added.

Because english is not my native english I had a bit problem understanding the task. For example it says sunk = all boats that are sunk which I understand as a list of all boats that are sunked. Maybe number of sunked boats etc. would be better.

I also agree that this is quite easy for a 4 kyu.

It should be mentioned that no matter how many times a ship was damaged we only get 0.5 point for each ship. And it's also unclear how to calculate points, for those having problems with figuring out points:

points = numberOfDamagedShips * 0.5 + numberOfSunkShips - notTouchedShips.

More test cases should be provided

By the way, I forgot to mention one thing the last time I reviewed this Kata. When comparing arrays, you may want to use the Test.assertSimilar or the Test.assertDeepEquals method instead of just using Test.expect so you can save yourself the trouble of writing an external function to compare two arrays. Hope this helps :)
