What are the basic interfaces of Java Collections Framework?

The basic interfaces of java collection framework are:
 
 Collection -Collection is the root of the collection hierarchy. It declares the core methods that all collections will have.
 Set - HashSet, LinkedHashSet classes implements this interface as it declare common method.
 List - ArrayList, LinkedList, Vector classes implements this interface as it declare common method
 Map - Hashtable, LinkedHashMap classes implements this interface as it declare common method
 SortedSet - TreeSet Class implements this interface to pre-sort its elements.
 SortedMap - TreeMap class implements this interface to pre-sort its emenets.
 Some other interfaces are Queue, Dequeue, Iterator, and ListIterator.
