Uses of Comparator in java.util

Classes in java.util that implement Comparator

private static class Collections.ReverseComparator
The implementation of Collections.reverseOrder() 55 .

Fields in java.util declared as Comparator

(package private) Comparator TreeMap.comparator
This TreeMap's comparator, or null for natural ordering.

Methods in java.util that return Comparator

static Comparator Collections.reverseOrder()
          Get a comparator that implements the reverse of natural ordering.

Comparator Collections.SynchronizedSortedMap.comparator()
          Returns the comparator used in sorting the underlying map, or null if it is the keys' natural ordering.

Comparator Collections.SynchronizedSortedSet.comparator()
          Returns the comparator used in sorting the underlying set, or null if it is the elements' natural ordering.

Comparator Collections.UnmodifiableSortedMap.comparator()
          Returns the comparator used in sorting the underlying map, or null if it is the keys' natural ordering.

Comparator Collections.UnmodifiableSortedSet.comparator()
          Returns the comparator used in sorting the underlying set, or null if it is the elements' natural ordering.

Comparator SortedMap.comparator()
          Returns the comparator used in sorting this map, or null if it is the keys' natural ordering.

Comparator TreeMap.comparator()
          Return the comparator used to sort this map, or null if it is by natural order.

Comparator TreeMap.SubMap.comparator()


Comparator SortedSet.comparator()
          Returns the comparator used in sorting this set, or null if it is the elements' natural ordering.

Comparator TreeSet.comparator()
          Returns this Set's comparator.

Methods in java.util with parameters of type Comparator

(package private) static int Collections.compare(java.lang.Object o1, java.lang.Object o2, Comparator c)
          Compare two objects with or without a Comparator.

static int Collections.binarySearch(List l, java.lang.Object key, Comparator c)
          Perform a binary search of a List for a key, using a supplied Comparator.

static java.lang.Object Collections.max(Collection c, Comparator order)
          Find the maximum element in a Collection, according to a specified Comparator.

static java.lang.Object Collections.min(Collection c, Comparator order)
          Find the minimum element in a Collection, according to a specified Comparator.

static void Collections.sort(List l, Comparator c)
          Sort a list according to a specified Comparator.

static int Arrays.binarySearch(java.lang.Object[] a, java.lang.Object key, Comparator c)
          Perform a binary search of an Object array for a key, using a supplied Comparator.

static void Arrays.sort(java.lang.Object[] a, Comparator c)
          Sort an array of Objects according to a Comparator.

static void Arrays.sort(java.lang.Object[] a, int fromIndex, int toIndex, Comparator c)
          Sort an array of Objects according to a Comparator.

Constructors in java.util with parameters of type Comparator

TreeMap(Comparator c)
Instantiate a new TreeMap with no elements, using the provided comparator to sort.

TreeSet(Comparator comparator)
Construct a new TreeSet whose backing TreeMap uses the supplied Comparator.
