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()           Returns the comparator used to order this map, or null if this map uses its keys' natural order.
Comparator<? super E>	PriorityQueue.comparator()           Returns the comparator used to order this collection, or null if this collection is sorted according to its elements natural ordering (using Comparable).
Comparator<? super E>	TreeSet.comparator()           Returns the comparator used to order this sorted set, or null if this tree set uses its elements natural ordering.
Comparator<? super E>	SortedSet.comparator()           Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.
Comparator<? super K>	SortedMap.comparator()           Returns the comparator associated with this sorted map, or null if it uses its keys' natural ordering.
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> c)           Constructs a new, empty map, sorted according to the given comparator.
TreeSet(Comparator<? super E> c)           Constructs a new, empty 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 this collection, or null if this collection is sorted according to its elements natural ordering (using Comparable).

 

Constructors in java.util.concurrent with parameters of type Comparator
PriorityBlockingQueue(int initialCapacity, Comparator<? super E> comparator)           Creates a PriorityBlockingQueue with the specified initial capacity that orders its elements according to the specified comparator.

 

Uses of Comparator in javax.swing

 

Methods in javax.swing that return Comparator
protected  Comparator<? super Component>	SortingFocusTraversalPolicy.getComparator()           Returns the Comparator which will be used to sort the Components in a focus traversal cycle.

 

Methods in javax.swing with parameters of type Comparator
protected  void	SortingFocusTraversalPolicy.setComparator(Comparator<? super Component> comparator)           Sets the Comparator which will be used to sort the Components in a focus traversal cycle.

 

Constructors in javax.swing with parameters of type Comparator
SortingFocusTraversalPolicy(Comparator<? super Component> comparator)           Constructs a SortingFocusTraversalPolicy with the specified Comparator.
