To convert aZonedDateTimeto aDate, we first need to convert theZonedDateTimeto anInstant, as bothZonedDateTimeandInstantrepresent points on the timeline suitable for conversion. Let’s see how we do it: publicstaticDateconvertToDate(ZonedDateTime zonedDateTime){returnDate.from(zonedDateTime.toI...
DateTimeconvertStringToZonedDateTime(StringdateStr){// 无需定义格式,直接解析ZonedDateTimezonedDateTime=null;try{// 将字符串转换为带时区的日期时间zonedDateTime=ZonedDateTime.parse(dateStr);}catch(DateTimeParseExceptione){System.err.println("日期时间格式错误: "+e.getMessage());}returnzonedDateTime;...
LocalDateTime以及ZonedDateTime使用 这两个时间的formate方法是返回DateTimeFormatter后的String 静态方法parse是返回对应的类型 例子如下 importlombok.extern.slf4j.Slf4j;importjava.time.LocalDateTime;importjava.time.ZoneId;importjava.time.ZonedDateTime;importjava.time.format.DateTimeFormatter;@Slf4jpublicclassJava8Da...

ZonedDateTime(ISO-8601 日历系统中带时区的日期时间),依此类推 OffsetDateTime(在 ISO-8601 日历系统中,有 UTC/GMT 偏移的日期时间) OffsetTime(在 ISO-8601 日历系统中与 UTC/GMT 有偏移的时间) 为了通过预定义的格式化程序将String转换为LocalDate,它应该遵循DateTimeFormatter.ISO_LOCAL_DATE模式,例如2020-06-...
Learn to convert a string to date time instance classes e.g.ZonedDateTimeorOffsetDateTimeclasses, usingDateTimeFormatterclass in Java. 1. Instant, OffsetDateTime and ZonedDateTime Classes In Java 8,OffsetDateTimeandZonedDateTime– both store an instant on the universal timeline to nanosecond precision....
ZonedDateTimezdt=ZonedDateTime.now();Instantinstant=zdt.toInstant();//in UTC 4. Conclusion In this shortJava date-time tutorial, we learned to convert fromInstanttoZonedDateTimeand reverse by adjusting the zone offsets. Happy Learning !!
