Package java.text

Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages.

See: Description

Interface Summary

Interface	Description
AttributedCharacterIterator	An AttributedCharacterIterator allows iteration through both text and related attribute information.
CharacterIterator	This interface defines a protocol for bidirectional iteration over text.

Class Summary

Class	Description
Annotation	An Annotation object is used as a wrapper for a text attribute value if the attribute has annotation characteristics.
AttributedCharacterIterator.Attribute	Defines attribute keys that are used to identify text attributes.
AttributedString	An AttributedString holds text and related attribute information.
Bidi	This class implements the Unicode Bidirectional Algorithm.
BreakIterator	The BreakIterator class implements methods for finding the location of boundaries in text.
ChoiceFormat	A ChoiceFormat allows you to attach a format to a range of numbers.
CollationElementIterator	The CollationElementIterator class is used as an iterator to walk through each character of an international string.
CollationKey	A CollationKey represents a String under the rules of a specific Collator object.
Collator	The Collator class performs locale-sensitive String comparison.
DateFormat	DateFormat is an abstract class for date/time formatting subclasses which formats and parses dates or time in a language-independent manner.
DateFormat.Field	Defines constants that are used as attribute keys in the AttributedCharacterIterator returned from DateFormat.formatToCharacterIterator and as field identifiers in FieldPosition.
DateFormatSymbols	DateFormatSymbols is a public class for encapsulating localizable date-time formatting data, such as the names of the months, the names of the days of the week, and the time zone data.
DecimalFormat	DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers.
DecimalFormatSymbols	This class represents the set of symbols (such as the decimal separator, the grouping separator, and so on) needed by DecimalFormat to format numbers.
FieldPosition	FieldPosition is a simple class used by Format and its subclasses to identify fields in formatted output.
Format	Format is an abstract base class for formatting locale-sensitive information such as dates, messages, and numbers.
Format.Field	Defines constants that are used as attribute keys in the AttributedCharacterIterator returned from Format.formatToCharacterIterator and as field identifiers in FieldPosition.
MessageFormat	MessageFormat provides a means to produce concatenated messages in a language-neutral way.
MessageFormat.Field	Defines constants that are used as attribute keys in the AttributedCharacterIterator returned from MessageFormat.formatToCharacterIterator.
Normalizer	This class provides the method normalize which transforms Unicode text into an equivalent composed or decomposed form, allowing for easier sorting and searching of text.
NumberFormat	NumberFormat is the abstract base class for all number formats.
NumberFormat.Field	Defines constants that are used as attribute keys in the AttributedCharacterIterator returned from NumberFormat.formatToCharacterIterator and as field identifiers in FieldPosition.
ParsePosition	ParsePosition is a simple class used by Format and its subclasses to keep track of the current position during parsing.
RuleBasedCollator	The RuleBasedCollator class is a concrete subclass of Collator that provides a simple, data-driven, table collator.
SimpleDateFormat	SimpleDateFormat is a concrete class for formatting and parsing dates in a locale-sensitive manner.
StringCharacterIterator	StringCharacterIterator implements the CharacterIterator protocol for a String.

Enum Summary

Enum	Description
Normalizer.Form	This enum provides constants of the four Unicode normalization forms that are described in Unicode Standard Annex #15 — Unicode Normalization Forms and two methods to access them.

Exception Summary

Exception	Description
ParseException	Signals that an error has been reached unexpectedly while parsing.

Package java.text Description

Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages. This means your main application or applet can be written to be language-independent, and it can rely upon separate, dynamically-linked localized resources. This allows the flexibility of adding localizations for new localizations at any time.

These classes are capable of formatting dates, numbers, and messages, parsing; searching and sorting strings; and iterating over characters, words, sentences, and line breaks. This package contains three main groups of classes and interfaces:

• Classes for iteration over text
• Classes for formatting and parsing
• Classes for string collation
