所有已实现的接口:

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()
```
    Create a DecimalFormatSymbols object for the default FORMAT 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.
    This is equivalent to calling DecimalFormatSymbols(Locale.getDefault(Locale.Category.FORMAT)).
    
    另请参阅:
    
    Locale.getDefault(java.util.Locale.Category), Locale.Category.FORMAT
  - 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. If the specified locale contains the Locale.UNICODE_LOCALE_EXTENSION for 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 a NumberFormat instance with the Thai numbering system, instead of the Latin numbering system.
    参数:
    
    locale - the desired locale
    
    抛出:
    
    NullPointerException - if locale is null
- 方法详细资料
  - 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.
    
    返回:
    
    an array of locales for which localized DecimalFormatSymbols instances are available.
