Operations on SortedSet

The operations that SortedSet inherits from Set behave identically on sorted sets and normal sets with two exceptions:

• The Iterator returned by the iterator operation traverses the sorted set in order.
• The array returned by toArray contains the sorted set's elements in order.

Although the interface doesn't guarantee it, the toString method of the JDK's SortedSet implementations returns a string containing all the elements of the sorted set, in order.
