用于计算两个LocalDate对象 相差的年数，月数，天数

常用方法

代码

package NewTime;

import java.time.LocalDate;
import java.time.Period;

public class Test_Period {
    public static void main(String[] args) {
        //传入两个日期对象的到一个 Period对象
        Period p = Period.between(LocalDate.of(2024, 8, 1), LocalDate.of(2024, 8, 31));
        System.out.println(p);
        //获取两个日期对象相差的年、月、日
        System.out.println(p.getYears());
        System.out.println(p.getMonths());
        System.out.println(p.getDays());

    }
}

During

常用方法

代码

package NewTime;

import java.time.Duration;
import java.time.LocalDateTime;

/**

public class Test_During {
    public static void main(String[] args) {
        //传入两个时间对象的到Duration对象
        LocalDateTime start = LocalDateTime.of(2020, 8, 31, 3, 3, 12);
        LocalDateTime end = LocalDateTime.of(2020, 9,30 , 3, 3, 12);
        Duration duration = Duration.between(start, end);

        //计算相隔的年
        Long years = duration.toDays() / 365 ;
        Long days = duration.toDays() ;
        Long hours = duration.toHours() ;
        Long minutes = duration.toMinutes() ;
        Long seconds = duration.getSeconds() ;
        Long millis = duration.toMillis() ;
        Long nanos = duration.toNanos() ;
        System.out.println("相隔的年数：" + years);
        System.out.println("相隔的天数：" + days);

    }
