如何计算年份中两个日期之间的差异...等与Joda-Time

import java.text.SimpleDateFormat;
import java.util.Date;
import org.joda.time.*;

public class Test {

  public static void main(String[] args) {

String dateStart = "01/01/2000 05:30";
String dateStop = "02/2/2001 06:31";

SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm");

Date d1 = null;
Date d2 = null;

try {
    d1 = format.parse(dateStart);
    d2 = format.parse(dateStop);

    DateTime dt1 = new DateTime(d1);
    DateTime dt2 = new DateTime(d2);

    System.out.print(Years.yearsBetween(dt1, dt2).getYears() + " years, ");
    System.out.print(Months.monthsBetween(dt1, dt2).getMonths() % 52 + " months, ");
    System.out.print(Weeks.weeksBetween(dt1, dt2).getWeeks() % 4 + " weeks, ");
    System.out.print(Days.daysBetween(dt1, dt2).getDays() % 7 + " days, ");
    System.out.print(Hours.hoursBetween(dt1, dt2).getHours() % 24 + " hours, ");
    System.out.print(Minutes.minutesBetween(dt1, dt2).getMinutes() % 60 + " minutes, ");


 } catch (Exception e) {
    e.printStackTrace();
 }

}

}

我想使用Joda-Time输出两个日期之间的年,月,周,天,小时和分钟数。我的问题是,我在哪里实现一个月的周数(这从来都不是恒定的)。我也不认为我的%是正确的。

当运行我得到:

1 years, 13 months, 0 weeks, 6 days, 1 hours, 1 minutes, 

答案 1

句点为您提供了开箱即用的功能。

Period period = new Period(d1, d2);
System.out.print(period.getYears() + " years, ");
System.out.print(period.getMonths() + " months, ");
// ...

为了美化并更好地控制输出,您可以使用 PeriodFormatterBuilder
