LocalDate专门处理日期,LocalTime专门处理时间,LocalDateTime包含了日期和时间,而且对于很多复杂的问题,都提供了现成的方法,比如:获取2017年12月的第一个周一等。...package test; import java.time.DayOfWeek; import java.time.LocalDate; import java.time.LocalDateTime...(); System.out.println(today); //构造日期 2017-10-08 LocalDate today2 = LocalDate.of...Test public void testTime() { LocalDateTime time = LocalDateTime.now(); System.out.println...startTime = LocalDateTime.of(2018, 1, 1, 20, 31, 20); LocalDateTime endTime = LocalDateTime.of
一 前言 二 时间戳与LocalDateTime互转 2.1 LocalDateTime 转 时间戳 方式一 这边值得一提的是在中国的时区偏移是8小时,本次示例转的时间戳是秒级别,得到的值是一个long...,不同的精确值,将获取不同的结果; 方式一 先获取时间戳为秒级别,然后通过转换为LocalDateTime @Test public void localTimeTest4(){ //获得时间戳 long...); } 三 时间戳与LocalDate互转 学会时间戳与LocalDate互转,同理就可以推出时间戳与LocalTime 互转,不过知识追寻者相信几乎没人会用到这个,故这边就不做示例; 3.1 时间戳转...3.2 LocalDate 转 时间戳 方式一 注意妙计时间戳 @Test public void localDateTest3(){ LocalDate localDate = LocalDate.now...与Date互转 5.1 LocalDate 转 Date @Test public void DateTest5(){ //当前时间 LocalDate localDate = LocalDate.now
概述 时间日期处理是平时工作中使用非常频繁的逻辑,Java8中提供的新的时间类LocalDateTime和LocalDate,使日期处理可以更简单。...友情提醒下,业务开发中最好默认使用LocalDateTime,因为LocalDateTime可以很方便的转换为LocalDate,但是LocalDate是不可以转为LocalDateTime的,会没有时分秒的数据...localDateTime = LocalDateTime.ofInstant(instant, zone); } // 02. java.util.Date –> java.time.LocalDate...localDateTime = LocalDateTime.ofInstant(instant, zone); LocalDate localDate = localDateTime.toLocalDate...localDate = LocalDate.now(); LocalDateTime localDateTime = LocalDateTime.of(localDate, localTime);

1.LocalDate转Date LocalDate nowLocalDate = LocalDate.now(); Date date = Date.from(nowLocalDate.atStartOfDay...(ZoneId.systemDefault()).toInstant()); 2.LocalDateTime转Date LocalDateTime localDateTime = LocalDateTime.now...(); 4.LocalDate转时间戳 LocalDate localDate = LocalDate.now(); long timestamp = localDate.atStartOfDay...(ZoneId.systemDefault()).toInstant().toEpochMilli(); 5.LocalDateTime转时间戳 LocalDateTime localDateTime...(); 6.时间戳转LocalDateTime(LocalDate) long timestamp = System.currentTimeMillis(); LocalDate localDate

二.Date转LocalDate 如果要将Java.util.Date转换为java.time.LocalDate,可以使用以下步骤: 1)将java.util.Date转换为ZonedDateTime...(“LocalDate = ” + localDate); } } 结果: Date = Fri Jun 16 15:29:05 CST 2017 LocalDate = 2017-06-16 三.LocalDate...转Date 现在,如果要将LocalDate转换回java.util.Date,可以使用以下步骤: 1)使用ZonedDateTime将LocalDate转换为Instant。...localDate = LocalDate.now(); ZonedDateTime zdt = localDate.atStartOfDay(zoneId); Date date = Date.from...(zdt.toInstant()); System.out.println(“LocalDate = ” + localDate); System.out.println(“Date = ” + date
根据两个日期之间获取LocalDate日历列表和LocalDate和LocalDateTime数据格式转换 package com.example.core.mydemo.localdatetime;...import java.time.LocalDate; import java.time.LocalDateTime; import java.time.format.DateTimeFormatter...)); } public static String formatLocalDateToString(LocalDate localDate,String format) {...(LocalDateTime localDateTime,String format) { DateTimeFormatter formatter = DateTimeFormatter.ofPattern...(format); return localDateTime.format(formatter); } }
大 LocalDate 转Date 1.需要先将LocalDate转为LocalDateTime LocalDate.atStartOfDay() 2....获取 Instance,需要指定时区,这里使用系统默认 LocalDateTime.atZone(ZoneId.systemDefault()).toInstant() 3.转化 Date.from()...连起来就是 Date.from(LocalDate.now().atStartOfDay().atZone(ZoneId.systemDefault()).toInstant()) Date转LocalDate...new Date().toInstant().atZone(ZoneId.systemDefault()).toLocalDate() 转载自:LocalDate转Date类型 – 简书 版权声明:本文内容由互联网用户自发贡献
2.2 java.time.LocalDateTime类的使用相比之下,java.time.LocalDateTime类提供了更强大、更灵活的日期和时间操作功能。...三、如何将1712560695839转换为日期?要将1712560695839转换为日期,可以使用java.time.Instant类和java.time.ZoneId类。...然后,使用系统默认的时区将其转换为ZonedDateTime对象。使用toLocalDate()方法将ZonedDateTime对象转换为LocalDate对象。...以下是实现这一转换的Java代码:import java.time.*;import java.time.format....localDate = zonedDateTime.toLocalDate(); System.out.println(localDate); }}这段代码会打印出与给定时间戳对应的日期
