[英]How to calculate difference between two dates in years…etc with 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();
}
}
}
I want to output the number of years, months, weeks, days, hours, and minutes between two dates using Joda-Time . 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。 My question is where do I implement the number of weeks in a month (which in never constant). 我的问题是,我应在哪里实施一个月中的周数(永远不会保持不变)。 I don't think my %'s are right either. 我也不认为我的%是正确的。
When run I get: 运行时,我得到:
1 years, 13 months, 0 weeks, 6 days, 1 hours, 1 minutes,
Period
gives you this out of the box. Period
让您开箱即用。
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
. 要美化并获得对输出的更多控制,可以使用PeriodFormatterBuilder
。
