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.
Get started now by creating a new collection.
And also no need to convert it to array and then find length, we can directly using count() terminal operation ( Need to downcast it to int though )
Not an issue.
Modified tests to call setters/getters, still figuring out how to ensure that variables are declared as private
fixed up, Thx and Regards,TDRS
