Did I miss/skip the lesson on arrays?

Okay, so I have to admit, at first I thought the tasks were a little too easy, but now I'm really struggling with the newer ones. I don't know if I should continue with the course or spend some more time and get a better grasp of all these subjects.

With Static Cats, I got a little too cute and did something that works and is super clean but the validation didn't like it. I used the Cat constructor to add itself to the cats ArrayList (i.e. "Cat.cats.add(this);"). However, after it failed validation I saw that they specifically want the Cat objects added to the ArrayList in the main method, so you can't do it in the constructor. My version is significantly shorter, but rules are rules.

Thanks for this. I did the exact same thing.

CAVEAT: task0614 ('Static cats') is underspecified. It seems that printCats() has to call toString() on each cat or something like that in order for the code to pass - a requirement that is not stated *anywhere*.

What is bothering me about these exercises is that they have to be written in a certain way. I am studying computer science in grad school, so I've created many classes before and so I have a certain style of writing them. When writing a class here, I get the solution wrong when I know they are right.

Really nice exercises again. Nice to see the introduction of the ArrayList, however they where already saving my ass few tasks ago so not completely new anymore.
