DateFormatSymbols is a public class for encapsulating localizable date-time formatting data, such as the names of the months, the names of the days of the week, and the time zone data. SimpleDateFormat uses DateFormatSymbols to encapsulate this information.
Typically you shouldn't use DateFormatSymbols directly. Rather, you are encouraged to create a date-time formatter with the DateFormat class's factory methods: getTimeInstance, getDateInstance, or getDateTimeInstance. These methods automatically create a DateFormatSymbols for the formatter so that you don't have to. After the formatter is created, you may modify its format pattern using the setPattern method. For more information about creating formatters using DateFormat's factory methods, see DateFormat.
If you decide to create a date-time formatter with a specific format pattern for a specific locale, you can do so with:
```
 new SimpleDateFormat(aPattern, DateFormatSymbols.getInstance(aLocale)).
 
```
DateFormatSymbols objects are cloneable. When you obtain a DateFormatSymbols object, feel free to modify the date-time formatting data. For instance, you can replace the localized date-time format pattern characters with the ones that you feel easy to remember. Or you can change the representative cities to your favorite ones.
New DateFormatSymbols subclasses may be added to support SimpleDateFormat for date-time formatting for additional locales.

public DateFormatSymbols()
```
    Construct a DateFormatSymbols object by loading format data from resources 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 DateFormatSymbolsProvider implementations. For full locale coverage, use the getInstance method.
    This is equivalent to calling DateFormatSymbols(Locale.getDefault(Locale.Category.FORMAT)).
    
    抛出:
    
    MissingResourceException - if the resources for the default locale cannot be found or cannot be loaded.

public DateFormatSymbols(Locale locale)

    Construct a DateFormatSymbols object by loading format data from resources 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 DateFormatSymbolsProvider implementations.

    参数:
    
    locale - the desired locale

```
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 DateFormatSymbolsProvider implementations. It must contain at least a Locale instance equal to Locale.US.
    
    返回:
    
    An array of locales for which localized DateFormatSymbols instances are available.

  - getInstance
```
public static final DateFormatSymbols getInstance()
```
    Gets the DateFormatSymbols instance for the default locale. This method provides access to DateFormatSymbols instances for locales supported by the Java runtime itself as well as for those supported by installed DateFormatSymbolsProvider implementations.
    This is equivalent to calling getInstance(Locale.getDefault(Locale.Category.FORMAT)).
    
    返回:
    
    a DateFormatSymbols instance.

public static final DateFormatSymbols getInstance(Locale locale)
```
    Gets the DateFormatSymbols instance for the specified locale. This method provides access to DateFormatSymbols instances for locales supported by the Java runtime itself as well as for those supported by installed DateFormatSymbolsProvider implementations.
    
    参数:
    
    locale - the given locale.
    
    返回:
    
    a DateFormatSymbols instance.
    
    抛出:

  - getEras
```
public String[] getEras()
```
    Gets era strings. For example: "AD" and "BC".
    
    返回:
    
    the era strings.
  - setEras
```
public void setEras(String[] newEras)
```
    Sets era strings. For example: "AD" and "BC".
    
    参数:
    
    newEras - the new era strings.
  - getMonths
```
public String[] getMonths()
```
    Gets month strings. For example: "January", "February", etc.
    If the language requires different forms for formatting and stand-alone usages, this method returns month names in the formatting form. For example, the preferred month name for January in the Czech language is ledna in the formatting form, while it is leden in the stand-alone form. This method returns "ledna" in this case. Refer to the Calendar Elements in the Unicode Locale Data Markup Language (LDML) specification for more details.
    
    返回:
    
    the month strings.
  - setMonths
```
public void setMonths(String[] newMonths)
```

    参数:
    
    newMonths - the new month strings.
  - getShortMonths
```
public String[] getShortMonths()
```
    Gets short month strings. For example: "Jan", "Feb", etc.
    If the language requires different forms for formatting and stand-alone usages, This method returns short month names in the formatting form. For example, the preferred abbreviation for January in the Catalan language is de gen. in the formatting form, while it is gen. in the stand-alone form. This method returns "de gen." in this case. Refer to the Calendar Elements in the Unicode Locale Data Markup Language (LDML) specification for more details.
    
    返回:
    
    the short month strings.
  - setShortMonths

```
public void setWeekdays(String[] newWeekdays)
```
    Sets weekday strings. For example: "Sunday", "Monday", etc.
    
    参数:
    
    newWeekdays - the new weekday strings. The array should be indexed by Calendar.SUNDAY, Calendar.MONDAY, etc.

```
    Sets ampm strings. For example: "AM" and "PM".
    
    参数:
    
    newAmpms - the new ampm strings.
  - getZoneStrings
```
public String[][] getZoneStrings()
```
    Gets time zone strings. Use of this method is discouraged; use TimeZone.getDisplayName() instead.
    The value returned is a two-dimensional array of strings of size n by m, where m is at least 5. Each of the n rows is an entry containing the localized names for a single TimeZone. Each such row contains (with i ranging from 0..n-1):
    - zoneStrings[i][0] - time zone ID
    - zoneStrings[i][1] - long name of zone in standard time
    - zoneStrings[i][2] - short name of zone in standard time
    - zoneStrings[i][3] - long name of zone in daylight saving time
    - zoneStrings[i][4] - short name of zone in daylight saving time
    The zone ID is not localized; it's one of the valid IDs of the TimeZone class that are not custom IDs. All other entries are localized names. If a zone does not implement daylight saving time, the daylight saving time names should not be used.
    If setZoneStrings has been called on this DateFormatSymbols instance, then the strings provided by that call are returned. Otherwise, the returned array contains names provided by the Java runtime and by installed TimeZoneNameProvider implementations.
    返回:
    
    the time zone strings.

```
public void setZoneStrings(String[][] newZoneStrings)
```
    Sets time zone strings. The argument must be a two-dimensional array of strings of size n by m, where m is at least 5. Each of the n rows is an entry containing the localized names for a single TimeZone. Each such row contains (with i ranging from 0..n-1):
    - zoneStrings[i][0] - time zone ID
    - zoneStrings[i][1] - long name of zone in standard time
    - zoneStrings[i][2] - short name of zone in standard time
    - zoneStrings[i][3] - long name of zone in daylight saving time
    - zoneStrings[i][4] - short name of zone in daylight saving time
    The zone ID is not localized; it's one of the valid IDs of the TimeZone class that are not custom IDs. All other entries are localized names.
    参数:
    
    newZoneStrings - the new time zone strings.
    
    抛出:
    
    IllegalArgumentException - if the length of any row in newZoneStrings is less than 5
    
    NullPointerException - if newZoneStrings is null
