Uses of Comparator in java.lang

 

Fields in java.lang declared as Comparator
static Comparator<String>	String.CASE_INSENSITIVE_ORDER           A Comparator that orders String objects as by compareToIgnoreCase.

 

Uses of Comparator in java.text

 

Classes in java.text that implement Comparator
class	Collator           The Collator class performs locale-sensitive String comparison.
class	RuleBasedCollator           The RuleBasedCollator class is a concrete subclass of Collator that provides a simple, data-driven, table collator.

 

Uses of Comparator in java.util

 

Methods in java.util that return Comparator
Comparator<? super K>	TreeMap.comparator()
Comparator<? super E>	PriorityQueue.comparator()           Returns the comparator used to order the elements in this queue, or null if this queue is sorted according to the natural ordering of its elements.
Comparator<? super E>	TreeSet.comparator()
Comparator<? super E>	SortedSet.comparator()           Returns the comparator used to order the elements in this set, or null if this set uses the natural ordering of its elements.
Comparator<? super K>	SortedMap.comparator()           Returns the comparator used to order the keys in this map, or null if this map uses the natural ordering of its keys.
static <T> Comparator<T>	Collections.reverseOrder()           Returns a comparator that imposes the reverse of the natural ordering on a collection of objects that implement the Comparable interface.
static <T> Comparator<T>	Collections.reverseOrder(Comparator<T> cmp)           Returns a comparator that imposes the reverse ordering of the specified comparator.

 

Methods in java.util with parameters of type Comparator
static <T> int	Collections.binarySearch(List<? extends T> list, T key, Comparator<? super T> c)           Searches the specified list for the specified object using the binary search algorithm.

static <T> int	Arrays.binarySearch(T[] a, T key, Comparator<? super T> c)           Searches the specified array for the specified object using the binary search algorithm.
static <T> T	Collections.max(Collection<? extends T> coll, Comparator<? super T> comp)           Returns the maximum element of the given collection, according to the order induced by the specified comparator.
static <T> T	Collections.min(Collection<? extends T> coll, Comparator<? super T> comp)           Returns the minimum element of the given collection, according to the order induced by the specified comparator.
static <T> Comparator<T>	Collections.reverseOrder(Comparator<T> cmp)           Returns a comparator that imposes the reverse ordering of the specified comparator.
static <T> void	Collections.sort(List<T> list, Comparator<? super T> c)           Sorts the specified list according to the order induced by the specified comparator.
static <T> void	Arrays.sort(T[] a, Comparator<? super T> c)           Sorts the specified array of objects according to the order induced by the specified comparator.
static <T> void	Arrays.sort(T[] a, int fromIndex, int toIndex, Comparator<? super T> c)           Sorts the specified range of the specified array of objects according to the order induced by the specified comparator.

 

Constructors in java.util with parameters of type Comparator
PriorityQueue(int initialCapacity, Comparator<? super E> comparator)           Creates a PriorityQueue with the specified initial capacity that orders its elements according to the specified comparator.
TreeMap(Comparator<? super K> comparator)           Constructs a new, empty tree map, ordered according to the given comparator.
TreeSet(Comparator<? super E> comparator)           Constructs a new, empty tree set, sorted according to the specified comparator.

 

Uses of Comparator in java.util.concurrent

 

Methods in java.util.concurrent that return Comparator
Comparator<? super E>	PriorityBlockingQueue.comparator()           Returns the comparator used to order the elements in this queue, or null if this queue uses the natural ordering of its elements.
Comparator<? super E>	ConcurrentSkipListSet.comparator()
Comparator<? super K>	ConcurrentSkipListMap.comparator()

 

Constructors in java.util.concurrent with parameters of type Comparator
