Uses of Map in java.util

Subinterfaces of Map in java.util

Modifier and Type	Interface and Description
interface	SortedMap A map that further guarantees that it will be in ascending key order, sorted according to the natural ordering of its keys (see the Comparable interface), or by a comparator provided at sorted map creation time.

Classes in java.util that implement Map

Modifier and Type	Class and Description
class	AbstractMap This class provides a skeletal implementation of the Map interface, to minimize the effort required to implement this interface.
class	HashMap Hash table based implementation of the Map interface.
class	Hashtable This class implements a hashtable, which maps keys to values.
class	IdentityHashMap This class implements the Map interface with a hash table, using reference-equality in place of object-equality when comparing keys (and values).
class	LinkedHashMap Hash table and linked list implementation of the Map interface, with predictable iteration order.
class	Properties The Properties class represents a persistent set of properties.
class	TreeMap Red-Black tree based implementation of the SortedMap interface.
class	WeakHashMap A hashtable-based Map implementation with weak keys.
