Zeitzonen?<\/figcaption><\/figure><\/div>\n\n\n\n

Wie k\u00f6nnen alle Zeitzonen mit Java ermittelt werden? Das geht mit der Methode getAvailableZoneIds<\/strong> der Klasse ZoneId<\/strong>. Die Methode ist thread save und der Set kann zuk\u00fcnftig noch erweitert werden. Bei mir ist er heute 600 Eintr\u00e4ge (IDs) gro\u00df, wie dieser JUnit Test zeigt:<\/p>\n\n\n\n

@Test
public void testGetAlleZeitzonen(){
List zeitZonen = new ArrayList<>(ZoneId.getAvailableZoneIds<\/strong>()); zeitZonen.stream().sorted().forEach(zone -> System.out.println(zone)); assertEquals(600<\/strong>, zeitZonen.size());<\/string>
}<\/string><\/p>\n\n\n\n

Das sind die Zeitzonen IDs:<\/p>\n\n\n\n\n\n\n\n
