Provides a list of Windows time zones (the zones in the time zone selection dialog in Windows), and their associated Java TimeZone objects. Data was obtained from the CLDR (http://unicode.org/repos/cldr/trunk/common/supplemental/windowsZones.xml). Contains a list of mappings in the following...
then you are going to need a list of time zones. You need this if you want to edit or display times in 'local time' and store them as UTC (universal time). This article shows the Java code and a handy Seam component that provides the list. ...
List<String> names = Arrays.asList("peter", "anna", "mike", "xenia"); Collections.sort(names, new Comparator<String>() { @Override public int compare(String a, String b) { return b.compareTo(a); } }); 只需要给静态方法 Collections.sort 传入一个List对象以及一个比较器来按指定顺序排列。
●LocalTime——它代表的是不含日期的时间●LocalDateTime——它包含了日期及时间,不过还是没有偏移信息或者说时区。●ZonedDateTime——这是一个包含时区的完整的日期时间还有时区,偏移量是以UTC/格林威治时间为基准的。●Timezones——时区。在新API中时区使用ZoneId来表示。时区可以很方便的使用静态方法of来获取到...
11.2 Timezones 时区 11.3 LocalTime 11.4 LocalDate 11.4 LocalDateTime 十二、Annotations 注解 小伙伴们,Java版本都到 12 啦,我发现还有很多小伙伴对 8 的新特性不是很了解。 所以我翻译这个 Java 8 指导手册,该手册在 GitHub 上有 1W+ 的 Star, 错不了。
TimeZone类现在是遗留类，几年前就被JSR310中定义的现代java.time类所取代。具体替换为java.time.Zone...
