Package java.text
package java.text
Provides classes and interfaces for handling text, dates, numbers,
and messages in a manner independent of natural languages. This
means an application or library 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
- Since:
- 1.1

All Classes and InterfacesInterfacesClassesEnum ClassesException ClassesClassDescriptionAn Annotation object is used as a wrapper for a text attribute value if the attribute has annotation characteristics.An
AttributedCharacterIteratorallows iteration through both text and related attribute information.Defines attribute keys that are used to identify text attributes.An AttributedString holds text and related attribute information.This class implements the Unicode Bidirectional Algorithm.TheBreakIteratorclass implements methods for finding the location of boundaries in text.This interface defines a protocol for bidirectional iteration over text.ChoiceFormatis a concrete subclass ofNumberFormatthat allows you to attach a format to a range of numbers.TheCollationElementIteratorclass is used as an iterator to walk through each character of an international string.ACollationKeyrepresents aStringunder the rules of a specificCollatorobject.TheCollatorclass performs locale-sensitiveStringcomparison.CompactNumberFormatis a concrete subclass ofNumberFormatthat formats a decimal number in a localized compact form.DateFormatis an abstract class for date/time formatting subclasses which formats and parses dates or time in a language-independent manner.Defines constants that are used as attribute keys in theAttributedCharacterIteratorreturned fromDateFormat.formatToCharacterIteratorand as field identifiers inFieldPosition.DateFormatSymbolsis 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.DecimalFormatis a concrete subclass ofNumberFormatthat formats decimal numbers in a localized manner.This class represents the set of symbols (such as the decimal separator, the grouping separator, and so on) needed byDecimalFormatto format numbers.FieldPositionis a simple class used byFormatand its subclasses to identify fields in formatted output.Formatis an abstract base class for formatting locale-sensitive information such as dates, messages, numbers, and lists.Defines constants that are used as attribute keys in theAttributedCharacterIteratorreturned fromFormat.formatToCharacterIteratorand as field identifiers inFieldPosition.ListFormatformats or parses a list of strings in a locale-sensitive way.MessageFormatprovides a means to produce concatenated messages in a language-neutral way.Defines constants that are used as attribute keys in theAttributedCharacterIteratorreturned fromMessageFormat.formatToCharacterIterator.This class provides the methodnormalizewhich transforms Unicode text into an equivalent composed or decomposed form, allowing for easier sorting and searching of text.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.NumberFormatis the abstract base class for all number formats.Defines constants that are used as attribute keys in theAttributedCharacterIteratorreturned fromNumberFormat.formatToCharacterIteratorand as field identifiers inFieldPosition.A number format style.Signals that an error has been reached unexpectedly while parsing.ParsePositionis a simple class used byFormatand its subclasses to keep track of the current position during parsing.TheRuleBasedCollatorclass is a concrete subclass ofCollatorthat provides a simple, data-driven, table collator.SimpleDateFormatis a concrete class for formatting and parsing dates in a locale-sensitive manner.StringCharacterIteratorimplements theCharacterIteratorprotocol for aString.
