下面程序使用了两种方法计算两个时间相差 天，小时，分钟，秒
package jodotest;
import java.text.ParseException;

public class Test {
public static void test1(Date d1, Date d2){
// 毫秒ms
long diff = d2.getTime() - d1.getTime();
long diffSeconds = diff / 1000 % 60;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);
System.out.print("时间相差：");
System.out.print(diffDays + " 天 ");
System.out.print(diffHours + " 小时 ");
System.out.print(diffMinutes + " 分钟 ");
System.out.print(diffSeconds + " 秒.");
System.out.println();
}
public static void test2(Date d1, Date d2) throws ParseException{
DateTime dt1 = new DateTime(d1);
DateTime dt2 = new DateTime(d2);
System.out.print("时间相差：");
System.out.print(Days.daysBetween(dt1, dt2).getDays() + " 天 ");
System.out.print(Hours.hoursBetween(dt1, dt2).getHours() % 24 + " 小时 ");
System.out.print(Minutes.minutesBetween(dt1, dt2).getMinutes() % 60 + " 分钟 ");
System.out.print(Seconds.secondsBetween(dt1, dt2).getSeconds() % 60+ " 秒.");
System.out.println();
}
public static void test3(Date d1, Date d2){
Interval interval = new Interval(d1.getTime(), d2.getTime());
Period p = interval.toPeriod();
System.out.println("时间相差："+p.getDays()+" 天 " + p.getHours()+ " 小时 "+p.getMinutes()+" 分钟"+p.getSeconds()+" 秒");
}
/**
* @param args
* @throws ParseException
*/
publicstaticvoid main(String[] args)throwsParseException{
String dateStart ="2013-08-13 16:29:58";
String dateStop ="2013-08-13 16:31:48";
SimpleDateFormat format =newSimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date d1 = format.parse(dateStart);
Date d2 = format.parse(dateStop);
test1(d1, d2);
test2(d1, d2);
test3(d1, d2);
}
}
程序输出：
时间相差：0 天 0 小时 1 分钟 50 秒.
时间相差：0 天 0 小时 1 分钟 50 秒.
时间相差：0 天 0 小时 1 分钟50 秒
可以看看，两种写法的优缺点。
