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.

Read the hint again, sample test (there is only one in Java) is just that, a sample, not the full test suite.
When I run Sample Test, it says that i passed. Then i click to Attempt, and it says test 2 and 3 failed. Where is the probleb? (Java)
very unclear and confusing what is expected to be the output after running the tests
