Class 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.

    • Method Detail

      • 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.

        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.

        Parameters:
        locale - the locale.
        ns - the numbering system.
        Returns:

      • getLocale

        public final ULocale getLocale​(ULocale.Type type)
        Returns the locale that was used to create this object, or null. This may may differ from the locale requested at the time of this object's creation. For example, if an object is created for locale en_US_CALIFORNIA, the actual data may be drawn from en (the actual locale), and en_US may be the most specific locale that exists (the valid locale).

        Note: The actual locale is returned correctly, but the valid locale is not, in most cases.

        Parameters:
        type - type of information requested, either ULocale.VALID_LOCALE or ULocale.ACTUAL_LOCALE.
        Returns:
        the information specified by type, or null if this object was not constructed from locale data.
