## Uses of Interface
java.util.Set

Packages that use Set
java.security |
java.security.cert |
java.util |
java.util.jar |

Uses of Set in java.security

Methods in java.security that return Set
`Set` | `Provider.entrySet()` Returns an unmodifiable Set view of the property entries contained in this Provider.
`Set` | `Provider.keySet()` Returns an unmodifiable Set view of the property keys contained in this provider.

Uses of Set in java.security.cert

Methods in java.security.cert that return Set
`Set` | `X509Extension.getCriticalExtensionOIDs()` Gets a Set of the OID strings for the extension(s) marked CRITICAL in the certificate/CRL managed by the object implementing this interface.
`Set` | `X509Extension.getNonCriticalExtensionOIDs()` Gets a Set of the OID strings for the extension(s) marked NON-CRITICAL in the certificate/CRL managed by the object implementing this interface.
`abstract Set` | `X509CRL.getRevokedCertificates()` Gets all the entries from this CRL.

Uses of Set in java.util

Subinterfaces of Set in java.util
`interface` | `SortedSet` A set that further guarantees that its iterator will traverse the set in ascending element order, sorted according to the natural ordering of its elements (see Comparable), or by a Comparator provided at sorted set creation time.

Classes in java.util that implement Set
`class` | `AbstractSet` This class provides a skeletal implementation of the `Set` interface to minimize the effort required to implement this interface.
`class` | `HashSet` This class implements the `Set` interface, backed by a hash table (actually a `HashMap` instance).
`class` | `TreeSet` This class implements the `Set` interface, backed by a `TreeMap` instance.

Fields in java.util declared as Set
`static Set` | `Collections.EMPTY_SET` The empty set (immutable).

Methods in java.util that return Set
`Set` | `Hashtable.keySet()` Returns a Set view of the keys contained in this Hashtable.
`Set` | `Hashtable.entrySet()` Returns a Set view of the entries contained in this Hashtable.
`Set` | `AbstractMap.keySet()` Returns a Set view of the keys contained in this map.
`abstract Set` | `AbstractMap.entrySet()` Returns a set view of the mappings contained in this map.
`static Set` | `Collections.unmodifiableSet(Set s)` Returns an unmodifiable view of the specified set.
`static Set` | `Collections.synchronizedSet(Set s)` Returns a synchronized (thread-safe) set backed by the specified set.
`static Set` | `Collections.singleton(Object o)` Returns an immutable set containing only the specified object.
`Set` | `WeakHashMap.entrySet()` Returns a `Set` view of the mappings in this map.
`Set` | `TreeMap.keySet()` Returns a Set view of the keys contained in this map.
`Set` | `TreeMap.entrySet()` Returns a set view of the mappings contained in this map.
`Set` | `HashMap.keySet()` Returns a set view of the keys contained in this map.
`Set` | `HashMap.entrySet()` Returns a collection view of the mappings contained in this map.
`Set` | `Map.keySet()` Returns a set view of the keys contained in this map.
`Set` | `Map.entrySet()` Returns a set view of the mappings contained in this map.

Methods in java.util with parameters of type Set
`static Set` | `Collections.unmodifiableSet(Set s)` Returns an unmodifiable view of the specified set.
`static Set` | `Collections.synchronizedSet(Set s)` Returns a synchronized (thread-safe) set backed by the specified set.

Uses of Set in java.util.jar

Methods in java.util.jar that return Set
`Set` | `Attributes.keySet()` Returns a Set view of the attribute names (keys) contained in this Map.
`Set` | `Attributes.entrySet()` Returns a Collection view of the attribute name-value mappings contained in this Map.
