Method Detail


public abstract String getDisplayName(String ID,
                                      boolean daylight,
                                      int style,
                                      Locale locale)

The given time zone ID is "GMT" or one of the names defined using "Zone" entries in the "tz database", a public domain time zone database at The data of this database is contained in a file whose name starts with "tzdata", and the specification of the data format is part of the zic.8 man page, which is contained in a file whose name starts with "tzcode".

If daylight is true, the method should return a name appropriate for daylight saving time even if the specified time zone has not observed daylight saving time in the past.

ID - a time zone ID string
daylight - if true, return the daylight saving name.
style - either TimeZone.LONG or TimeZone.SHORT
locale - the desired locale
the human-readable name of the given time zone in the given locale, or null if it's not available.
IllegalArgumentException - if style is invalid, or locale isn't one of the locales returned from getAvailableLocales().
NullPointerException - if ID or locale is null
