| 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 | 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 | 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 | Description | 
|---|---|
| ParseException | 
 Signals that an error has been reached unexpectedly
 while parsing. 
 | 
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:
