Package java.text

packagejava.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

    Description
    Service provider classes for the classes in the java.text package.

    Description
    An Annotation object is used as a wrapper for a text attribute value if the attribute has annotation characteristics.
    AnAttributedCharacterIterator allows 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.
    TheBreakIterator class implements methods for finding the location of boundaries in text.
    This interface defines a protocol for bidirectional iteration over text.
    ChoiceFormat is a concrete subclass ofNumberFormat that allows you to attach a format to a range of numbers.
    TheCollationElementIterator class is used as an iterator to walk through each character of an international string.
    ACollationKey represents aString under the rules of a specificCollator object.
    TheCollator class performs locale-sensitiveString comparison.
    CompactNumberFormat is a concrete subclass ofNumberFormat that formats a decimal number in a localized compact form.
    DateFormat is 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 theAttributedCharacterIterator returned fromDateFormat.formatToCharacterIterator and as field identifiers inFieldPosition.
    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 is a concrete subclass ofNumberFormat that 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 byDecimalFormat to format numbers.
    FieldPosition is a simple class used byFormat and its subclasses to identify fields in formatted output.
    Format is 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 theAttributedCharacterIterator returned fromFormat.formatToCharacterIterator and as field identifiers inFieldPosition.
    ListFormat formats or parses a list of strings in a locale-sensitive way.
    A ListFormat style -FULL,SHORT, andNARROW.
    A ListFormat type -STANDARD,OR, andUNIT.
    MessageFormat provides a means to produce concatenated messages in a language-neutral way.
    Defines constants that are used as attribute keys in theAttributedCharacterIterator returned fromMessageFormat.formatToCharacterIterator.
    This class provides the methodnormalize which 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.
    NumberFormat is the abstract base class for all number formats.
    Defines constants that are used as attribute keys in theAttributedCharacterIterator returned fromNumberFormat.formatToCharacterIterator and as field identifiers inFieldPosition.
    A number format style.
    Signals that an error has been reached unexpectedly while parsing.
    ParsePosition is a simple class used byFormat and its subclasses to keep track of the current position during parsing.
    TheRuleBasedCollator class is a concrete subclass ofCollator that provides a simple, data-driven, table collator.
    SimpleDateFormat is a concrete class for formatting and parsing dates in a locale-sensitive manner.
    StringCharacterIterator implements theCharacterIterator protocol for aString.
