set-->
when uniqueness is required you need to implement set.
e.g.
HashSet(unOrd,unSort) Fast access, assures no duplicates,
provides no ordering.
LinkedHashSet(Ord,unSort)No duplicates; iterates by
insertion order.
TreeSet(ascending,naturalord)No duplicates ; iterates in
sorted order.
list-->
when ordered list is required you need to implement list.
e.g.
ArrayList(Ord,unSort)Fast iteration and fast random access.
Vector(syncronized)
LinkedList()Good for adding elements to the ends, i.e.,
stacks and queues.

Answer / vinod varma
set is an interface which doesnot allows the duplicate values
where as list is also an interface which allows the
duplicate values and we may not guarantee the order of
elements in set
but we can get the elements from list according to their
indexes. we may not insert the elements into set at the
specific index, but possible in list.
