private static final List<Card> protoDeck = new ArrayList<Card>();

**static** {

I have a quick question. The code block that starts right after the static keyword declaration, what type of method is that ? I haven't ever seen that before. If anyone could enlighten me, that would be greatly appreciated. Thanks.
