## Uses of Interface
java.util.SortedSet

Packages that use SortedSet
java.util: Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
java.util.concurrent: Utility classes commonly useful in concurrent programming.

### Uses of SortedSet in java.util

Subinterfaces of SortedSet in java.util
`interface` `NavigableSet<E>` A `SortedSet` extended with navigation methods reporting closest matches for given search targets.

Classes in java.util that implement SortedSet
`class` `TreeSet<E>` A `NavigableSet` implementation based on a `TreeMap`.

Methods in java.util that return SortedSet
`static <E> SortedSet<E>` Collections.`checkedSortedSet(SortedSet<E> s, Class<E> type)` Returns a dynamically typesafe view of the specified sorted set.
`static <E> SortedSet<E>` Collections.`emptySortedSet()` Returns an empty sorted set (immutable).
`SortedSet<E>` NavigableSet.`headSet(E toElement)` Returns a view of the portion of this set whose elements are strictly less than `toElement`.
`SortedSet<E>` TreeSet.`headSet(E toElement)`
`SortedSet<E>` SortedSet.`headSet(E toElement)` Returns a view of the portion of this set whose elements are strictly less than `toElement`.
`SortedSet<E>` NavigableSet.`subSet(E fromElement, E toElement)` Returns a view of the portion of this set whose elements range from `fromElement`, inclusive, to `toElement`, exclusive.
`SortedSet<E>` TreeSet.`subSet(E fromElement, E toElement)`
`SortedSet<E>` SortedSet.`subSet(E fromElement, E toElement)` Returns a view of the portion of this set whose elements range from `fromElement`, inclusive, to `toElement`, exclusive.
`static <T> SortedSet<T>` Collections.`synchronizedSortedSet(SortedSet<T> s)` Returns a synchronized (thread-safe) sorted set backed by the specified sorted set.
`SortedSet<E>` NavigableSet.`tailSet(E fromElement)` Returns a view of the portion of this set whose elements are greater than or equal to `fromElement`.
`SortedSet<E>` TreeSet.`tailSet(E fromElement)`
`SortedSet<E>` SortedSet.`tailSet(E fromElement)` Returns a view of the portion of this set whose elements are greater than or equal to `fromElement`.
`static <T> SortedSet<T>` Collections.`unmodifiableSortedSet(SortedSet<T> s)` Returns an unmodifiable view of the specified sorted set.

Methods in java.util with parameters of type SortedSet
`static <E> SortedSet<E>` Collections.`checkedSortedSet(SortedSet<E> s, Class<E> type)` Returns a dynamically typesafe view of the specified sorted set.
`static <T> SortedSet<T>` Collections.`synchronizedSortedSet(SortedSet<T> s)` Returns a synchronized (thread-safe) sorted set backed by the specified sorted set.
`static <T> SortedSet<T>` Collections.`unmodifiableSortedSet(SortedSet<T> s)` Returns an unmodifiable view of the specified sorted set.

Constructors in java.util with parameters of type SortedSet
Constructor and Description
`PriorityQueue(SortedSet<? extends E> c)` Creates a `PriorityQueue` containing the elements in the specified sorted set.
`TreeSet(SortedSet<E> s)` Constructs a new tree set containing the same elements and using the same ordering as the specified sorted set.

### Uses of SortedSet in java.util.concurrent

Classes in java.util.concurrent that implement SortedSet
`class` `ConcurrentSkipListSet<E>` A scalable concurrent `NavigableSet` implementation based on a `ConcurrentSkipListMap`.

Constructors in java.util.concurrent with parameters of type SortedSet
Constructor and Description
`ConcurrentSkipListSet(SortedSet<E> s)` Constructs a new set containing the same elements and using the same ordering as the specified sorted set.
