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.
