Module java.base

Package java.text

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
Since:
1.1
  • 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.
    CompactNumberFormat
    CompactNumberFormat is a concrete subclass of NumberFormat that formats a decimal number in its compact form.
    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.
    NumberFormat.Style
    A number format style.
  • Exception Summary 
    Exception Description
    ParseException
    Signals that an error has been reached unexpectedly while parsing.
