DecimalFormatSymbols (Java Platform SE 8 )

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.

- Constructor Detail
  - 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)).
    
    See Also:
    
    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.
    Parameters:
    
    locale - the desired locale
    
    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.
    This is equivalent to calling getInstance(Locale.getDefault(Locale.Category.FORMAT)).
    
    Returns:
    
    a DecimalFormatSymbols instance.
    
    Since:
    
    1.6
    
    See Also:
    
    Locale.getDefault(java.util.Locale.Category), Locale.Category.FORMAT
  - 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. 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.
    Parameters:
    
    locale - the desired locale.
    
    Returns:
    
    a DecimalFormatSymbols instance.
    
    Throws:
    
    NullPointerException - if locale is null
