DateFormatSymbols
public DateFormatSymbols()
- Throws:
MissingResourceException- if the resources for the default locale cannot be found or cannot be loaded.- See Also:
getInstance(),Locale.getDefault(java.util.Locale.Category),Locale.Category.FORMAT
-
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 installed
DateFormatSymbolsProviderimplementations. For full locale coverage, use thegetInstancemethod.- Parameters:
locale- the desired locale- 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 the
getInstancemethods of this class can return localized instances. The returned array represents the union of locales supported by the Java runtime and by installedDateFormatSymbolsProviderimplementations. It must contain at least aLocaleinstance equal toLocale.US.- Returns:
- An array of locales for which localized
DateFormatSymbolsinstances are available. - Since:
- 1.6
-
getInstance
public static final DateFormatSymbols getInstance()
- Returns:
- a
DateFormatSymbolsinstance. - Since:
- 1.6
- See Also:
Locale.getDefault(java.util.Locale.Category),Locale.Category.FORMAT
-
getInstance
public static final DateFormatSymbols getInstance(Locale locale)
Gets the
DateFormatSymbolsinstance for the specified locale. This method provides access toDateFormatSymbolsinstances for locales supported by the Java runtime itself as well as for those supported by installedDateFormatSymbolsProviderimplementations.- Parameters:
locale- the given locale.- Returns:
- a
DateFormatSymbolsinstance. - Throws:
NullPointerException- iflocaleis null- Since:
- 1.6
-
getEras
public String[] getEras()
Gets era strings. For example: "AD" and "BC".
- Returns:
- the era strings.
-
setEras
public void setEras(String[] newEras)
Sets era strings. For example: "AD" and "BC".
- Parameters:
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.- Returns:
- the month strings. Use
Calendar.JANUARY,Calendar.FEBRUARY, etc. to index the result array.
-
setMonths
public void setMonths(String[] newMonths)
Sets month strings. For example: "January", "February", etc.
- Parameters:
newMonths- the new month strings. The array should be indexed byCalendar.JANUARY,Calendar.FEBRUARY, etc.
-
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.- Returns:
- the short month strings. Use
Calendar.JANUARY,Calendar.FEBRUARY, etc. to index the result array.
-
setShortMonths
public void setShortMonths(String[] newShortMonths)
Sets short month strings. For example: "Jan", "Feb", etc.
- Parameters:
newShortMonths- the new short month strings. The array should be indexed byCalendar.JANUARY,Calendar.FEBRUARY, etc.
-
getWeekdays
public String[] getWeekdays()
Gets weekday strings. For example: "Sunday", "Monday", etc.
- Returns:
- the weekday strings. Use
Calendar.SUNDAY,Calendar.MONDAY, etc. to index the result array.
-
setWeekdays
public void setWeekdays(String[] newWeekdays)
Sets weekday strings. For example: "Sunday", "Monday", etc.
- Parameters:
newWeekdays- the new weekday strings. The array should be indexed byCalendar.SUNDAY,Calendar.MONDAY, etc.
-
getShortWeekdays
public String[] getShortWeekdays()
Gets short weekday strings. For example: "Sun", "Mon", etc.
- Returns:
- the short weekday strings. Use
Calendar.SUNDAY,Calendar.MONDAY, etc. to index the result array.
-
setShortWeekdays
public void setShortWeekdays(String[] newShortWeekdays)
Sets short weekday strings. For example: "Sun", "Mon", etc.
- Parameters:
newShortWeekdays- the new short weekday strings. The array should be indexed byCalendar.SUNDAY,Calendar.MONDAY, etc.
-
getAmPmStrings
public String[] getAmPmStrings()
Gets ampm strings. For example: "AM" and "PM".
- Returns:
- the ampm strings.
-
setAmPmStrings
public void setAmPmStrings(String[] newAmpms)
Sets ampm strings. For example: "AM" and "PM".
- Parameters:
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 (withiranging from 0..n-1):zoneStrings[i][0]- time zone IDzoneStrings[i][1]- long name of zone in standard timezoneStrings[i][2]- short name of zone in standard timezoneStrings[i][3]- long name of zone in daylight saving timezoneStrings[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
TimeZoneclass 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
setZoneStringshas been called on thisDateFormatSymbolsinstance, then the strings provided by that call are returned. Otherwise, the returned array contains names provided by the Java runtime and by installedTimeZoneNameProviderimplementations.- Returns:
- the time zone strings.

setZoneStrings(String[][])
-
setZoneStrings
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 (withiranging from 0..n-1):zoneStrings[i][0]- time zone IDzoneStrings[i][1]- long name of zone in standard timezoneStrings[i][2]- short name of zone in standard timezoneStrings[i][3]- long name of zone in daylight saving timezoneStrings[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
TimeZoneclass that are not custom IDs. All other entries are localized names.- Parameters:
newZoneStrings- the new time zone strings.- Throws:
IllegalArgumentException- if the length of any row innewZoneStringsis less than 5NullPointerException- ifnewZoneStringsis null- See Also:
