Classes in java.util that implement Map

Modifier and Type	Class and Description
class	AbstractMap<K,V> This class provides a skeletal implementation of the Map interface, to minimize the effort required to implement this interface.
class	EnumMap<K extends Enum<K>,V> A specialized Map implementation for use with enum type keys.
