remove operation), the results of the iteration are
undefined.
The returned map has an ordering equivalent to
Collections.reverseOrder(comparator()). The expression
m.descendingMap().descendingMap() returns a view of m essentially equivalent to m.
ONavigableSet<K> navigableKeySet()
ONavigableSet view of the keys contained in this map. The set's iterator returns the keys in ascending order.
The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an
iteration over the set is in progress (except through the iterator's own remove operation), the results of the
iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the
Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not
support the add or addAll operations.ONavigableSet<K> descendingKeySet()
