public class DateFormatSymbols extends Object implements Serializable, Cloneable
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.DateFormat
andSimpleDateFormat
both useDateFormatSymbols
to encapsulate this information.Typically you shouldn't use
DateFormatSymbols
directly. Rather, you are encouraged to create a date-time formatter with theDateFormat
class's factory methods:getTimeInstance
,getDateInstance
, orgetDateTimeInstance
. These methods automatically create aDateFormatSymbols
for the formatter so that you don't have to. After the formatter is created, you may modify its format pattern using thesetPattern
method. For more information about creating formatters usingDateFormat
's factory methods, seeDateFormat
.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 aDateFormatSymbols
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 supportSimpleDateFormat
for date-time formatting for additional locales.- See Also:

Constructor Detail
-
DateFormatSymbols
public DateFormatSymbols()
Construct a DateFormatSymbols object by loading format data from resources for the default locale. This constructor can only construct instances for the locales supported by the Java runtime environment, not for those supported by installedDateFormatSymbolsProvider
implementations. For full locale coverage, use thegetInstance
method.- Throws:
MissingResourceException
- if the resources for the default locale cannot be found or cannot be loaded.- See Also:
getInstance()
-
DateFormatSymbols
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 installedDateFormatSymbolsProvider
implementations. For full locale coverage, use thegetInstance
method.- Throws:
MissingResourceException
- if the resources for the specified locale cannot be found or cannot be loaded.- See Also:
getInstance(Locale)
-

Method Detail
-
getAvailableLocales
public static Locale[] getAvailableLocales()
Returns an array of all locales for which thegetInstance
methods of this class can return localized instances. The returned array represents the union of locales supported by the Java runtime and by installedDateFormatSymbolsProvider
implementations. It must contain at least aLocale
instance equal toLocale.US
.- Returns:
- An array of locales for which localized
DateFormatSymbols
instances are available. - Since:
- 1.6
-
getInstance
public static final DateFormatSymbols getInstance()
Gets theDateFormatSymbols
instance for the default locale. This method provides access toDateFormatSymbols
instances for locales supported by the Java runtime itself as well as for those supported by installedDateFormatSymbolsProvider
implementations.- Returns:
- a
DateFormatSymbols
instance. - Since:
- 1.6
-
getInstance
public static final DateFormatSymbols getInstance(Locale locale)
Gets theDateFormatSymbols
instance for the specified locale. This method provides access toDateFormatSymbols
instances for locales supported by the Java runtime itself as well as for those supported by installedDateFormatSymbolsProvider
implementations.- Parameters:
locale
- the given locale.- Returns:
- a
DateFormatSymbols
instance. - Throws:
NullPointerException
- iflocale
is null- Since:
- 1.6
-
getEras

newEras
- the new era strings.
-
getMonths
public String[] getMonths()
Gets month strings. For example: "January", "February", etc.- Returns:
- the month strings.
-
setMonths
public void setMonths(String[] newMonths)

-
setShortMonths
public void setShortMonths(String[] newShortMonths)
Sets short month strings. For example: "Jan", "Feb", etc.- Parameters:
newShortMonths
- the new short month strings.
-
getWeekdays
public String[] getWeekdays()
Gets weekday strings. For example: "Sunday", "Monday", etc.- Returns:
