Interface Summary | |
Collection | Interface that represents a collection of objects. |
Comparator | Interface for objects that specify an ordering between objects. |
Enumeration | Interface for lists of objects that can be returned in sequence. |
EventListener | Empty interface that is implemented by classes that need to receive events. |
Formattable |
The Formattable interface is used to provide customised
formatting to arbitrary objects via the Formatter . |
Iterator | An object which iterates over a collection. |
List | An ordered collection (also known as a list). |
ListIterator | An extended version of Iterator to support the extra features of Lists. |
Map | An object that maps keys onto values. |
Map.Entry | A map entry (key-value pair). |
Observer | Interface that is implemented when a class wants to be informed of changes in Observable objects. |
RandomAccess | Marker interface used to inform List implementations that
they support fast (usually constant time) random access. |
Set | A collection that contains no duplicates. |
SortedMap | A map which guarantees its key's iteration order. |
SortedSet | A set which guarantees its iteration order. |
Class Summary | |
AbstractCollection | A basic implementation of most of the methods in the Collection interface to make it easier to create a collection. |
AbstractList | A basic implementation of most of the methods in the List interface to make it easier to create a List based on a random-access data structure. |
AbstractMap | An abstract implementation of Map to make it easier to create your own implementations. |
AbstractSequentialList | Abstract superclass to make it easier to implement the List interface when backed by a sequential-access store, such as a linked list. |
AbstractSet | An abstract implementation of Set to make it easier to create your own implementations. |
ArrayList | An array-backed implementation of the List interface. |
Arrays | This class contains various static utility methods performing operations on arrays, and a method to provide a List "view" of an array to facilitate using arrays with Collection-based APIs. |
BitSet | This class can be thought of in two ways. |
Calendar | This class is an abstract base class for Calendars, which can be
used to convert between Date objects and a set of
integer fields which represent YEAR ,
MONTH , DAY , etc. |
Collections | Utility class consisting of static methods that operate on, or return Collections. |
Currency | Representation of a currency for a particular locale. |
Date | This class represents a specific time in milliseconds since the epoch. |
Dictionary | A Dictionary maps keys to values; how it does that is implementation-specific. |
EventListenerProxy | An abstract wrapper for event listeners. |
EventObject | Represents Events fired by Objects. |
FormattableFlags | This class contains a set of flags used
by the Formattable.formatTo() method.
|
Formatter |
A Java formatter for printf -style format strings,
as seen in the C programming language. |
GregorianCalendar | This class represents the Gregorian calendar, that is used in most countries all over the world. |
HashMap | This class provides a hashtable-backed implementation of the Map interface. |
HashSet | This class provides a HashMap-backed implementation of the Set interface. |
Hashtable | A class which implements a hashtable data structure. |
IdentityHashMap | This class provides a hashtable-backed implementation of the Map interface, but uses object identity to do its hashing. |
LinkedHashMap | This class provides a hashtable-backed implementation of the Map interface, with predictable traversal order. |
LinkedHashSet | This class provides a hashtable-backed implementation of the Set interface, with predictable traversal order. |
LinkedList | Linked list implementation of the List interface. |
ListResourceBundle | A ListResouceBundle provides an easy way, to create your own
resource bundle. |
Locale | Locales represent a specific country and culture. |
Observable | This class represents an object which is observable. |
Properties | A set of persistent properties, which can be saved or loaded from a stream. |
PropertyPermission | This class represents the permission to access and modify a property. The name is the name of the property, e.g. xxx. |
PropertyResourceBundle | This class is a concrete ResourceBundle that gets it
resources from a property file. |
Random | This class generates pseudorandom numbers. |
ResourceBundle | A resource bundle contains locale-specific data. |
SimpleTimeZone | This class represents a simple time zone offset and handles daylight savings. |
Stack | |
StringTokenizer | This class splits a string into tokens. |
Timer | Timer that can run TimerTasks at a later time. |
TimerTask | Task that can be run at a later time if given to a Timer. |
TimeZone | This class represents a time zone offset and handles daylight savings. |
TreeMap | This class provides a red-black tree implementation of the SortedMap interface. |
TreeSet | This class provides a TreeMap-backed implementation of the SortedSet interface. |
UUID | This class represents a 128-bit UUID value. |
Vector | The Vector classes implements growable arrays of Objects.
|
WeakHashMap | A weak hash map has only weak references to the key. |
Exception Summary | |
ConcurrentModificationException | Exception that is thrown by the collections classes when it is detected that a modification has been made to a data structure when this is not allowed, such as when a collection is structurally modified while an Iterator is operating over it. |
DuplicateFormatFlagsException | Thrown when the flags supplied to the Formatter.format()
method of a Formatter contain duplicates.
|
EmptyStackException | This exception is thrown by the Stack class when an attempt is made to pop or otherwise access elements from an empty stack. |
FormatFlagsConversionMismatchException | Thrown when the flags supplied to the Formatter.format()
method of a Formatter contains a flag that does not match
the conversion character specified for it.
|
FormatterClosedException | Thrown when a method is called on a Formatter but
it has already been closed.
|
IllegalFormatCodePointException | Thrown when a Formatter receives a character with an
invalid Unicode codepoint, as defined by
Character.isValidCodePoint(int) .
|
IllegalFormatConversionException | Thrown when the type of an argument supplied to the
Formatter.format() method of a Formatter
does not match the conversion character specified for it.
|
IllegalFormatException | A general exception thrown when a format string is supplied
to a Formatter that contains either invalid syntax
or a mismatch between the format specification and the
supplied arguments. |
IllegalFormatFlagsException | Thrown when the flags supplied to the Formatter.format()
method of a Formatter form an illegal combination.
|
IllegalFormatPrecisionException | Thrown when the specified precision for a Formatter
argument is illegal. |
IllegalFormatWidthException | Thrown when the specified width for a Formatter
argument is illegal. |

between the input data and the pattern it is trying to match it
against. |
