Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Like @goodman965 saying, i think all this codes with s.split(" ") are not working if there is double-spaces inside the given string, meanwhile if you use s.split("\s+") you are taking care of any number of spaces.
Kata's should be tagged with the level of dificulty, this one was way too easy , i though it would be something more challenging.
Really nice kumite there mate, nice coding, just one small advice, remember classes in Java start with capital letter. Like this NthFib.
