| CharacterIterator This interface defines a protocol for bidirectional iteration over text. | 
| CollationElementIterator The  CollationElementIteratorclass is used as an iterator
 to walk through each character of an international string. | 
| CollationKey A  CollationKeyrepresents aStringunder the
 rules of a specificCollatorobject. | 
| Collator The  Collatorclass performs locale-sensitiveStringcomparison. | 
| DateFormat DateFormatis 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
  AttributedCharacterIteratorreturned
 fromDateFormat.formatToCharacterIteratorand as
 field identifiers inFieldPosition. | 
| DateFormatSymbols 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. | 
| DecimalFormatSymbols This class represents the set of symbols (such as the decimal separator,
 the grouping separator, and so on) needed by  DecimalFormatto format numbers. |

 that are described in
 
 Unicode Standard Annex #15 — Unicode Normalization Forms
 and two methods to access them. | 
| NumberFormat NumberFormatis the abstract base class for all number
 formats. | 
| NumberFormat.Field Defines constants that are used as attribute keys in the
  AttributedCharacterIteratorreturned
 fromNumberFormat.formatToCharacterIteratorand as
