## Class DecimalFormatSymbols

- java.lang.Object
- - java.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.

  `Locale`, `DecimalFormat`, Serialized Form

### Constructor Detail

#### DecimalFormatSymbols

    public DecimalFormatSymbols()

Create a DecimalFormatSymbols object for the default locale. This constructor can only construct instances for the locales supported by the Java runtime environment, not for those supported by installed `DecimalFormatSymbolsProvider` implementations. For full locale coverage, use the `getInstance` method.

#### DecimalFormatSymbols

    public DecimalFormatSymbols(Locale locale)

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 installed `DecimalFormatSymbolsProvider` implementations. For full locale coverage, use the `getInstance` method.

Throws:
  `NullPointerException` - if `locale` is null

### Method Detail

#### getAvailableLocales

    public static Locale[] getAvailableLocales()

Returns an array of all locales for which the `getInstance` methods of this class can return localized instances. The returned array represents the union of locales supported by the Java runtime and by installed `DecimalFormatSymbolsProvider` implementations. It must contain at least a `Locale` instance equal to `Locale.US`.

Returns:
  An array of locales for which localized `DecimalFormatSymbols` instances are available.
Since:
  1.6

#### getInstance

    public static final DecimalFormatSymbols getInstance()

Gets the `DecimalFormatSymbols` instance for the default locale. This method provides access to `DecimalFormatSymbols` instances for locales supported by the Java runtime itself as well as for those supported by installed `DecimalFormatSymbolsProvider` implementations.

Returns:
  a `DecimalFormatSymbols` instance.
Since:
  1.6

#### getInstance

    public static final DecimalFormatSymbols getInstance(Locale locale)

Gets the `DecimalFormatSymbols` instance for the specified locale. This method provides access to `DecimalFormatSymbols` instances for locales supported by the Java runtime itself as well as for those supported by installed `DecimalFormatSymbolsProvider` implementations.

Parameters:
  `locale` - the desired locale.
Returns:
  a `DecimalFormatSymbols` instance.
Throws:
  `NullPointerException` - if `locale` is null
Since:
  1.6
