【Java】API 时区ID类

主要是用以获取时区ID

@Test
void contextLoads() {
    ZoneId zoneId = ZoneId.systemDefault();
    // System.out.println(zoneId); // 时区ID Asia/Shanghai

    // 获取可用的时区ID
    Set<String> availableZoneIds = ZoneId.getAvailableZoneIds();
    for (String availableZoneId : availableZoneIds) {
        System.out.println(availableZoneId);
    }
