Description
Interface Summary | |
Collection | The root interface in the collection hierarchy. |
Comparator | A comparison function, which imposes a total ordering on some collection of objects. |
Enumeration | An object that implements the Enumeration interface generates a series of elements, one at a time. |
EventListener | A tagging interface that all event listener interfaces must extend |
Iterator | An iterator over a collection. |
List | An ordered collection (also known as a sequence). |
ListIterator | An iterator for lists that allows the programmer to traverse the list in either direction and modify the list during iteration. |
Map | An object that maps keys to values. |
Map.Entry | A map entry (key-value pair). |
Observer | A class can implement the Observer interface when it
wants to be informed of changes in observable objects. |
Set | A collection that contains no duplicate elements. |
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. |
SortedSet | A set that further guarantees that its iterator will traverse the set in ascending element order, sorted according to the natural ordering of its elements (see Comparable), or by a Comparator provided at sorted set creation time. |
Class Summary | |
AbstractCollection | This class provides a skeletal implementation of the Collection interface, to minimize the effort required to implement this interface. |
AbstractList | This class provides a skeletal implementation of the List interface to minimize the effort required to implement this interface backed by a "random access" data store (such as an array). |
AbstractMap | This class provides a skeletal implementation of the Map interface, to minimize the effort required to implement this interface. |
AbstractSequentialList | This class provides a skeletal implementation of the List interface to minimize the effort required to implement this interface backed by a "sequential access" data store (such as a linked list). |
AbstractSet | This class provides a skeletal implementation of the Set interface to minimize the effort required to implement this interface. |
ArrayList | Resizable-array implementation of the List interface. |
Arrays | This class contains various methods for manipulating arrays (such as sorting and searching). |
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. |
Date | The class Date represents a specific instant
in time, with millisecond precision. |
Dictionary | The Dictionary class is the abstract parent of any
class, such as Hashtable , which maps keys to values. |
EventObject | The Event class is the abstract root class from which all event state objects shall be derived. |
GregorianCalendar | GregorianCalendar is a concrete subclass of
Calendar
and provides the standard calendar used by most of the world. |
HashMap | Hash table based implementation of the Map interface. |
HashSet | This class implements the Set interface, backed by a hash table (actually a HashMap instance). |
Hashtable | This class implements a hashtable, which maps keys to values. |
LinkedList | Linked list implementation of the List interface. |
ListResourceBundle | ListResourceBundle is a abstract subclass of
ResourceBundle that manages resources for a locale
in a convenient and easy to use list. |
Locale | A Locale object represents a specific geographical, political,
or cultural region. |
Observable | This class represents an observable object, or "data" in the model-view paradigm. |
Properties | The Properties class represents a persistent set of
properties. |
PropertyPermission | This class is for property permissions. |
PropertyResourceBundle | PropertyResourceBundle is a concrete subclass of
ResourceBundle that manages resources for a locale
using a set of static strings from a property file. |
Random | An instance of this class is used to generate a stream of pseudorandom numbers. |
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. |
Stack | The Stack class represents a last-in-first-out
(LIFO) stack of objects. |
StringTokenizer | The string tokenizer class allows an application to break a string into tokens. |
TimeZone | TimeZone represents a time zone offset, and also figures out daylight
savings. |
TreeMap | Red-Black tree based implementation of the SortedMap interface. |
TreeSet | This class implements the Set interface, backed by a TreeMap instance. |
Vector | The Vector class implements a growable array of
objects. |
WeakHashMap | A hashtable-based Map implementation with weak keys. |
Exception Summary | |
ConcurrentModificationException | This exception may be thrown by methods that have detected concurrent modification of a backing object when such modification is not permissible. |
EmptyStackException | Thrown by methods in the Stack class to indicate
that the stack is empty. |
MissingResourceException | Signals that a resource is missing. |
NoSuchElementException | Thrown by the nextElement method of an
Enumeration to indicate that there are no more
elements in the enumeration. |
TooManyListenersException |
The TooManyListenersException Exception is used as part of
the Java Event model to annotate and implement a unicast special case of
a multicast Event Source. |
Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
