Package java.util

Added Classes and Interfaces
Currency	Represents a currency.
EventListenerProxy	An abstract wrapper class for an EventListener class which associates a set of additional parameters with the listener.
IdentityHashMap	This class implements the Map interface with a hash table using reference-equality in place of object-equality when comparing keys (and values).
LinkedHashMap	Hash table and linked list implementation of the Map interface with predictable iteration order.
LinkedHashSet	Hash table and linked list implementation of the Set interface with predictable iteration order.
RandomAccess	Marker interface used by List implementations to indicate that they support fast (generally constant time) random access.

 

Changed Classes
AbstractMap	This class provides a skeletal implementation of the Map interface to minimize the effort required to implement this interface.
ArrayList	Resizable-array implementation of the List interface.
BitSet	This class implements a vector of bits that grows as needed.
Calendar	Calendar is an abstract base class for converting between a Date object and a set of integer fields such as YEAR MONTH DAY HOUR and so on.
Collections	This class consists exclusively of static methods that operate on or return collections.
Hashtable	This class implements a hashtable which maps keys to values.
Locale	A Locale object represents a specific geographical political or cultural region.
ResourceBundle	Resource bundles contain locale-specific objects.
SimpleTimeZone	SimpleTimeZone is a concrete subclass of TimeZone that represents a time zone for use with a Gregorian calendar.
TimeZone	TimeZone represents a time zone offset and also figures out daylight savings.
Vector	The Vector class implements a growable array of objects.
WeakHashMap	A hashtable-based Map implementation with weak keys.
