What are the API of java time and date

This article mainly talks about "what are the API of java time and date". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what are the API of java time and date"?

1. Clock provides the ability to access the current time and date. Clock is sensitive to the current time zone and can be used instead of System.currenttimeMillis () to get the current millisecond time.

Clock clock = Clock.systemDefaultZone (); long millis = clock.millis (); Instant instant = clock.instant (); Date legacyDate = Date.from (instant); / / legacy java.util.Date

2. The local time class represents a time that does not have a specified time zone.

LocalTime now1 = LocalTime.now (zone1); LocalTime now2 = LocalTime.now (zone2); System.out.println (now1.isBefore (now2)); / / false long hoursBetween = ChronoUnit.HOURS.between (now1, now2); long minutesBetween = ChronoUnit.MINUTES.between (now1, now2); System.out.println (hoursBetween); / /-3System.out.println (minutesBetween); / /-239

3. Time zone classes can be represented by ZoneId. Objects of the time zone class can be easily obtained through the static factory method.

System.out.println (ZoneId.getAvailableZoneIds ()); / / prints all available timezone ids ZoneId zone1 = ZoneId.of ("Europe/Berlin"); ZoneId zone2 = ZoneId.of ("Brazil/East"); System.out.println (zone1.getRules ()); System.out.println (zone2.getRules ()); / / ZoneRules [currentStandardOffset=+01:00] / / ZoneRules [currentStandardOffset =-03:00] so far, I believe you have a deeper understanding of "java time and date API", you might as well do it in practice!
