Hey. Collections has a static wrapper method that will give you synchronization on your ArrayList<>, so really, shouldn't we be considering that rather than just saying you "definitely wouldn't use ArrayList<> if multi-threaded"? I also would say that ArrayList<> is just fine for adding as long as all the adds come at the end and not in the beginning or the middle. Pretty good in general, tho.

I feel you should have given proper examples and used methods on them. That would have been more understandable. But good videos.
