How to calculate difference between two dates in years...etc with Joda-Time
提问by MrAwesome8
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();
}
}
}
I want to output the number of years, months, weeks, days, hours, and minutes between two dates using Joda-Time. My question is where do I implement the number of weeks in a month (which in never constant). I don't think my %'s are right either.
我想使用Joda-Time 输出两个日期之间的年数、月数、周数、天数、小时数和分钟数。我的问题是我在哪里实施一个月中的周数（永远不会恒定）。我也不认为我的 % 是对的。
When run I get:
运行时我得到：
1 years, 13 months, 0 weeks, 6 days, 1 hours, 1 minutes,

Periodgives you this out of the box.
Period为您提供开箱即用的功能。
Period period = new Period(d1, d2);
System.out.print(period.getYears() + " years, ");
System.out.print(period.getMonths() + " months, ");
// ...
To prettify and get a little more control over the output, you can use a PeriodFormatterBuilder.
要美化并更好地控制输出，您可以使用PeriodFormatterBuilder.
