Java程序获取时区ID字符串
让我们获取美国时区的时区ID字符串。为此，请使用get.AvailableZoneIds()方法-
ZoneId.getAvailableZoneIds().stream().filter(s ->s.startsWith("America"))
.forEach(System.out::println);这样，我们就使用了forEach来显示美国的所有时区-
America/Cuiaba America/Marigot America/El_Salvador America/Guatemala America/Belize America/Panama America/Managua America/Indiana/Petersburg America/Chicago America/Tegucigalpa America/Eirunepe America/Miquelon . . .
示例
import java.time.ZoneId;
public class Demo {
public static void main(String[] args) {
System.out.println("TimeZones in the US");
ZoneId.getAvailableZoneIds().stream().filter(s ->s.startsWith("America"))
.forEach(System.out::println);
}
}输出结果
TimeZones in the US America/Cuiaba America/Marigot America/El_Salvador America/Guatemala America/Belize America/Panama America/Managua America/Indiana/Petersburg America/Chicago America/Tegucigalpa America/Eirunepe America/Miquelon America/Argentina/Catamarca America/Grand_Turk America/Argentina/Cordoba America/Araguaina America/Argentina/Salta America/Montevideo America/Manaus America/Argentina/Mendoza America/Argentina/Rio_Gallegos America/Catamarca America/Godthab America/Cordoba America/Regina America/Fort_Wayne America/Dawson_Creek America/St_Johns America/St_Thomas America/Anguilla America/Denver America/Havana America/Porto_Acre America/Barbados America/Louisville America/Sao_Paulo America/Curacao America/Guyana America/Guayaquil America/Martinique America/Puerto_Rico America/Rankin_Inlet America/Argentina/Jujuy America/Port_of_Spain America/Cayenne America/Rainy_River America/Yellowknife America/Juneau America/Indiana/Vevay America/Recife America/Buenos_Aires America/Noronha America/Swift_Current America/Metlakatla America/Paramaribo America/Indiana/Vincennes America/Kralendijk America/Antigua America/Indianapolis America/Inuvik America/Iqaluit America/Moncton America/St_Vincent America/Kentucky/Louisville America/Yakutat America/Mazatlan America/Dominica America/Mendoza America/Santarem America/Asuncion America/Boise America/Costa_Rica America/Dawson America/Indiana/Knox America/North_Dakota/Beulah America/Maceio America/Atka America/Monterrey America/Nassau America/Jamaica America/Atikokan America/Sitka America/Kentucky/Monticello America/Coral_Harbour America/Aruba America/North_Dakota/Center America/Cayman America/Indiana/Tell_City America/Tijuana America/Chihuahua America/Ojinaga America/Anchorage America/Halifax America/Indiana/Indianapolis America/Argentina/San_Luis America/Santiago America/Argentina/Ushuaia America/La_Paz America/Thunder_Bay America/Indiana/Marengo America/Creston America/Punta_Arenas America/Mexico_City America/Matamoros America/Blanc-Sablon America/Knox_IN America/Bogota America/Menominee America/Adak America/Resolute America/Edmonton America/Santo_Domingo America/Glace_Bay America/Port-au-Prince America/St_Barthelemy America/Nipigon America/Fortaleza America/Hermosillo America/Cancun America/Lima America/St_Lucia America/Bahia_Banderas America/Montserrat America/Santa_Isabel America/Cambridge_Bay America/Lower_Princes America/Vancouver America/Rio_Branco America/Danmarkshavn America/Detroit America/Thule America/Argentina/La_Rioja America/Tortola America/Porto_Velho America/Scoresbysund America/Nome America/Campo_Grande America/Belem America/Ensenada America/Jujuy America/Bahia America/Goose_Bay America/Virgin America/Pangnirtung America/Phoenix America/Whitehorse America/Montreal America/Argentina/San_Juan America/Indiana/Winamac America/Argentina/ComodRivadavia America/Boa_Vista America/Grenada America/Argentina/Tucuman America/New_York America/Merida America/Rosario America/St_Kitts America/Fort_Nelson America/Caracas America/Guadeloupe America/North_Dakota/New_Salem America/Shiprock America/Winnipeg America/Toronto America/Los_Angeles America/Argentina/Buenos_Aires
