Uses of Comparator in java.util

Classes in java.util that implement Comparator

private static class

Collections.ReverseComparator

Fields in java.util declared as Comparator

private static Comparator	Collections.REVERSE_ORDER
private Comparator	TreeMap.comparator The Comparator used to maintain order in this TreeMap, or null if this TreeMap uses its elements natural ordering.

Methods in java.util that return Comparator

static Comparator	Collections.reverseOrder() Returns a comparator that imposes the reverse of the natural ordering on a collection of objects that implement the Comparable interface.
Comparator	Collections.UnmodifiableSortedSet.comparator()
Comparator	Collections.UnmodifiableSortedMap.comparator()
Comparator	Collections.SynchronizedSortedSet.comparator()
Comparator	Collections.SynchronizedSortedMap.comparator()
Comparator	TreeSet.comparator() Returns the comparator used to order this sorted set, or null if this tree map uses its keys natural ordering.
Comparator	SortedSet.comparator() Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.
Comparator	TreeMap.comparator() Returns the comparator used to order this map, or null if this map uses its keys' natural order.
Comparator	TreeMap.SubMap.comparator()
Comparator	SortedMap.comparator() Returns the comparator associated with this sorted map, or null if it uses its keys' natural ordering.

Methods in java.util with parameters of type Comparator

static void	Collections.sort(List list, Comparator c) Sorts the specified list according to the order induced by the specified comparator.
static int	Collections.binarySearch(List list, Object key, Comparator c) Searches the specified list for the specified object using the binary search algorithm.
static Object	Collections.min(Collection coll, Comparator comp) Returns the minimum element of the given collection, according to the order induced by the specified comparator.
static Object	Collections.max(Collection coll, Comparator comp) Returns the maximum element of the given collection, according to the order induced by the specified comparator.
static void	Arrays.sort(Object[] a, Comparator c) Sorts the specified array of objects according to the order induced by the specified comparator.
static void	Arrays.sort(Object[] a, int fromIndex, int toIndex, Comparator c) Sorts the specified range of the specified array of objects according to the order induced by the specified comparator.
private static void	Arrays.mergeSort(Object[] src, Object[] dest, int low, int high, Comparator c)
static int	Arrays.binarySearch(Object[] a, Object key, Comparator c) Searches the specified array for the specified object using the binary search algorithm.
