Class DecimalFormatSymbols

java.lang.Object
com.ibm.icu.text.DecimalFormatSymbols
All Implemented Interfaces:
Serializable, Cloneable

public class DecimalFormatSymbols extends Object implements Cloneable, Serializable
. 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.

    • DecimalFormatSymbols

      public DecimalFormatSymbols(Locale locale)
      Creates a DecimalFormatSymbols object for the given locale.
      Parameters:
      locale - the locale
    • DecimalFormatSymbols

      public DecimalFormatSymbols(ULocale locale)
      Creates a DecimalFormatSymbols object for the given locale.
      Parameters:
      locale - the locale
  • Method Details

    • getInstance

      public static DecimalFormatSymbols getInstance()
      Returns a DecimalFormatSymbols instance for the default locale.

      Note: Unlike java.text.DecimalFormatSymbols#getInstance, this method simply returns new com.ibm.icu.text.DecimalFormatSymbols(). ICU currently does not support DecimalFormatSymbolsProvider, which was introduced in Java 6.

      Returns:
      A DecimalFormatSymbols instance.
    • getInstance

      public static DecimalFormatSymbols getInstance(Locale locale)
      Returns a DecimalFormatSymbols instance for the given locale.

      Note: Unlike java.text.DecimalFormatSymbols#getInstance, this method simply returns new com.ibm.icu.text.DecimalFormatSymbols(locale). ICU currently does not support DecimalFormatSymbolsProvider, which was introduced in Java 6.

      Parameters:
      locale - the locale.
      Returns:
      A DecimalFormatSymbols instance.
    • getInstance

      public static DecimalFormatSymbols getInstance(ULocale locale)
      Returns a DecimalFormatSymbols instance for the given locale.

      Note: Unlike java.text.DecimalFormatSymbols#getInstance, this method simply returns new com.ibm.icu.text.DecimalFormatSymbols(locale). ICU currently does not support DecimalFormatSymbolsProvider, which was introduced in Java 6.

      Parameters:

    • forNumberingSystem

      public static DecimalFormatSymbols forNumberingSystem(Locale locale, NumberingSystem ns)
      Returns a DecimalFormatSymbols instance for the given locale with digits and symbols corresponding to the given NumberingSystem.

      This method behaves equivalently to getInstance() called with a locale having a "numbers=xxxx" keyword specifying the numbering system by name.

      In this method, the NumberingSystem argument will be used even if the locale has its own "numbers=xxxx" keyword.

      Parameters:
      locale - the locale.
      ns - the numbering system.
      Returns:
      A DecimalFormatSymbols instance.

      Returns a DecimalFormatSymbols instance for the given locale with digits and symbols corresponding to the given NumberingSystem.

      This method behaves equivalently to getInstance() called with a locale having a "numbers=xxxx" keyword specifying the numbering system by name.

      In this method, the NumberingSystem argument will be used even if the locale has its own "numbers=xxxx" keyword.

      Parameters:
      locale - the locale.
      ns - the numbering system.
      Returns:
      A DecimalFormatSymbols instance.

      Returns:
      An array of Locales for which localized DecimalFormatSymbols instances are available.
    • getAvailableULocales

      public static ULocale[] getAvailableULocales()
      Returns an array of all locales for which the getInstance methods of this class can return localized instances.

      Note: Unlike java.text.DecimalFormatSymbols#getAvailableLocales, this method simply returns the array of ULocales available in this class. ICU currently does not support DecimalFormatSymbolsProvider, which was introduced in Java 6.
