java.text

  • The java.text package provides classes and interfaces for handling text, dates, numbers, and messages in a locale-sensitive manner.

  • It includes functionalities for formatting, parsing, and manipulating textual data, such as breaking strings into words or sentences.

  • The package offers various classes for working with dates and times, including formatting and parsing them according to different locales.

  • Number formatting and parsing are also addressed, enabling the representation of numbers in various formats based on locale-specific conventions.

  • Classes for handling messages are provided, allowing the creation and manipulation of messages that can be localized for different languages and regions.

Interfaces

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

Classes

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. 
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. 
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. 
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. 
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. 

Enums

Normalizer.Form The normalization forms supported by the Normalizer. 

Exceptions

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