SortedSet<E>
subSet
(E start, E end)
Returns a SortedSet of the specified portion of this SortedSet which
contains elements greater or equal to the start element but less than the
end element. The returned SortedSet is backed by this SortedMap so
changes to one are reflected by the other.
Parameters

SortedSet<E>
tailSet
(E start)
Returns a SortedSet of the specified portion of this SortedSet which
contains elements greater or equal to the start element. The returned
SortedSet is backed by this SortedSet so changes to one are reflected by
the other.
