Remove comment to use `isEmpty()` from Hamming analyzer

So I'm getting this recommendation on the hamming practice exercise.

And checking the solutions that are mostly like the one in as reference in the exercise definition, I'm not understanding how this helps improve the code.

Because if both strands are empty the code works properly and the count is 0, there is even a test that checks that

Thanks for the feedback! You make an excellent point, I think the logic in the analyzer was built before the exercise was updated here: exercism/java@239ad32. Previously it expected students to explicitly not allow empty strands, but that was recently removed.

I think we should update the analyzer to reflect this. Would you be willing to open a PR to fix it?

Sure!
