If you know how to use:

List
HashMap
TreeMap
arrays
Stack
Queue

you're 95% of the way there.

If you're looking for extra credit these days I'd add in more sophisticated ones like:

ConcurrentHashMap
CopyOnWriteArrayList
PriorityQueue
BlockingQueue

That looks to be 10.

I would add Set (such as HashSet) to Doug's list.

This heavily depends on your project's requirements. But in general the most widely used I'd say are lists/arrays and hash maps.

Oops - mccarl is absolutely right about Set.  That's important to include.
