Java8处理日期和时间

1.Instant 时间点

package com.company;

import java.time.Duration;
import java.time.Instant;

public class Main {

    public static void main(String[] args) {
        // Instant可表示的时间范围：±10亿年
        Instant min = Instant.MIN;
        Instant max = Instant.MAX;

        Instant start = Instant.now();
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        Instant end = Instant.now();
        // 计算两个时刻之间的时间量
        Duration timeElapsed = Duration.between(start, end);

        long millis = timeElapsed.toMillis();

        System.out.println("Instant的时间范围：" + min + "  至  " + max);
        System.out.println("时间差：" + millis);

    }
}

2.LocalDate 本地时间

// 构建LocalDate对象
LocalDate now = LocalDate.now();
LocalDate date1 = LocalDate.of(1903, 6, 14);
LocalDate date2 = LocalDate.of(1903, Month.JUNE, 14);
// 获取时间间隔
long until = date2.until(now, ChronoUnit.DAYS);
System.out.println(until);

3.TemporalAdjusters 日期调整器
