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)); 
new SimpleDateFormat(aPattern, DateFormatSymbols.getInstance(aLocale));

If the locale contains "rg" (region override) Unicode extension, the symbols are overridden for the designated region.

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.

Constructor Detail

DateFormatSymbolsback to summary
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)).

Exceptions
MissingResourceException:
if the resources for the default locale cannot be found or cannot be loaded.

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. For full locale coverage, use the getInstance method.

Parameters
locale:Locale

the desired locale

Exceptions
MissingResourceException:
if the resources for the specified locale cannot be found or cannot be loaded.

Method Detail

cloneback to summary
public Object clone()

Overrides java.lang.Object.clone.

Overrides Cloneable

copyMembersback to summary
private void copyMembers(DateFormatSymbols src, DateFormatSymbols dst)

Clones all the data members from the source DateFormatSymbols to the target DateFormatSymbols.

Parameters

equalsback to summary
public boolean equals(Object obj)

Overrides java.lang.Object.equals.

Compares the specified object with this DateFormatSymbols for equality. Returns true if the object is also a DateFormatSymbols and the two DateFormatSymbols objects represent the same date-time formatting data.

Implementation Specification

This method performs an equality check with a notion of class identity based on getClass(), rather than instanceof. Therefore, in the equals methods in subclasses, no instance of this class should compare as equal to an instance of a subclass.

Parameters
obj:Object

object to be compared for equality

Returns:boolean

true if the specified object is equal to this DateFormatSymbols

getLocalPatternCharsback to summary
public String getLocalPatternChars()

Gets localized date-time pattern characters. For example: 'u', 't', etc.

Returns:String

the localized date-time pattern characters.

getMonthsback to summary
public String[] getMonths()

Gets month strings. For example: "January", "February", etc. An array with either 12 or 13 elements will be returned depending on whether or not Calendar.UNDECIMBER is supported. Use Calendar.JANUARY, Calendar.FEBRUARY, etc. to index the result array.

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.

Implementation Specification

This method returns 13 elements since Calendar.UNDECIMBER is supported.

Returns:String[]

the month strings.

External Specification

getProviderInstanceback to summary
private static DateFormatSymbols getProviderInstance(Locale locale)
getShortMonthsback to summary
public String[] getShortMonths()

Gets short month strings. For example: "Jan", "Feb", etc. An array with either 12 or 13 elements will be returned depending on whether or not Calendar.UNDECIMBER is supported. Use Calendar.JANUARY, Calendar.FEBRUARY, etc. to index the result array.

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.

Implementation Specification

This method returns 13 elements since Calendar.UNDECIMBER is supported.

Returns:int

the index of the given time zone ID. Returns -1 if the given time zone ID can't be located in the DateFormatSymbols object.

See Also
java.util.SimpleTimeZone
getZoneStringsback to summary
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.

Returns:String[][]

the time zone strings.
