Concurrency

Wow, I was debugging something about threads, and found out about concurrency, by getting a ConcurrentModification exception. I read up on it, and I was modifying an arraylist in 2 threads at the same time. So I changed it to a CopyOnWriteArrayList (feel free to call any fault…). I never heard about atomic variables though. Thanks WikiDuke!

You should probably take a step back and read up a bit on concurrency before proceeding, or you’ll end up with lots of bugs that are extremely hard to debug.

I did. Took a look at the java tutorials on concurrency. Very good read.
