java.text.DecimalFormatSymbols
- All Implemented Interfaces:
Serializable,Cloneable
This class represents the set of symbols (such as the decimal separator,
the grouping separator, and so on) needed by
DecimalFormat
to format numbers. DecimalFormat creates for itself an instance of
DecimalFormatSymbols from its locale data. If you need to change any
of these symbols, you can get the DecimalFormatSymbols object from
your DecimalFormat and modify it.
If the locale contains "rg" (region override) Unicode extension, the symbols are overridden for the designated region.

DecimalFormatSymbols
public DecimalFormatSymbols()Create a DecimalFormatSymbols object for the defaultFORMATlocale. This constructor can only construct instances for the locales supported by the Java runtime environment, not for those supported by installedDecimalFormatSymbolsProviderimplementations. For full locale coverage, use thegetInstancemethod.This is equivalent to calling
DecimalFormatSymbols(Locale.getDefault(Locale.Category.FORMAT)). -
DecimalFormatSymbols
Create a DecimalFormatSymbols object for the given locale. This constructor can only construct instances for the locales supported by the Java runtime environment, not for those supported by installedDecimalFormatSymbolsProviderimplementations. For full locale coverage, use thegetInstancemethod. If the specified locale contains theLocale.UNICODE_LOCALE_EXTENSIONfor the numbering system, the instance is initialized with the specified numbering system if the JRE implementation supports it. For example,NumberFormat.getNumberInstance(Locale.forLanguageTag("th-TH-u-nu-thai"))This may return aNumberFormatinstance with the Thai numbering system, instead of the Latin numbering system.- Parameters:
locale- the desired locale- Throws:
NullPointerException- iflocaleis null

Method Details
-
getAvailableLocales
Returns an array of all locales for which thegetInstancemethods of this class can return localized instances. The returned array represents the union of locales supported by the Java runtime and by installedDecimalFormatSymbolsProviderimplementations. It must contain at least aLocaleinstance equal toLocale.US.- Returns:
- an array of locales for which localized
DecimalFormatSymbolsinstances are available. - Since:
- 1.6
-
getInstance
Gets theDecimalFormatSymbolsinstance for the default locale. This method provides access toDecimalFormatSymbolsinstances for locales supported by the Java runtime itself as well as for those supported by installedDecimalFormatSymbolsProviderimplementations.This is equivalent to calling
getInstance(Locale.getDefault(Locale.Category.FORMAT)).- Returns:
- a
DecimalFormatSymbolsinstance. - Since:
- 1.6
- See Also:

getInstance
Gets theDecimalFormatSymbolsinstance for the specified locale. This method provides access toDecimalFormatSymbolsinstances for locales supported by the Java runtime itself as well as for those supported by installedDecimalFormatSymbolsProviderimplementations. If the specified locale contains theLocale.UNICODE_LOCALE_EXTENSIONfor the numbering system, the instance is initialized with the specified numbering system if the JRE implementation supports it. For example,NumberFormat.getNumberInstance(Locale.forLanguageTag("th-TH-u-nu-thai"))This may return aNumberFormatinstance with the Thai numbering system, instead of the Latin numbering system.- Parameters:
