I think there are only 5% - 10% questions related to Collection Framework, you should remember the basic interfaces and corresponding implementations of collection:

interfaces Collection Set List Map
implementations Hashtable Vector HashSet TreeSet ArrayList LinkedList HashMap Map

remember when to use which, when usually relates to, like, a set of unique numbers, etc.

here're some useful links:
