Uses of Set in java.util

Subinterfaces of Set in java.util

interface SortedSet
A set which guarantees its iteration order.

Classes in java.util that implement Set

          The implementation of Collections.unmodifiableSet(Set) 55 .

private static class Collections.UnmodifiableSortedSet
          The implementation of Collections.synchronizedSortedMap(SortedMap) 55 .

class HashSet
          This class provides a HashMap-backed implementation of the Set interface.

class LinkedHashSet
          This class provides a hashtable-backed implementation of the Set interface, with predictable traversal order.

class TreeSet
          This class provides a TreeMap-backed implementation of the SortedSet interface.

private class WeakHashMap.WeakEntrySet
          The entry set.

Fields in java.util declared as Set

private Set Hashtable.keys
          The cache for Hashtable.keySet() 55 .

          The cache for HashMap.entrySet() 55 .

static Set Collections.EMPTY_SET
          An immutable, serializable, empty Set.

private Set Collections.SingletonMap.entries
          Cache the entry set.

private Set Collections.SynchronizedMap.entries
          Cache the entry set.

private Set Collections.SynchronizedMap.keys
          Cache the key set.

private Set Collections.UnmodifiableMap.entries
          Cache the entry set.
