Difference between hours (MM/dd/yyyy HH:mm:ss.SSS)

Question

I have to implement a java program to make the difference between two hours. The problem is that my "hour pattern" is like this:

MM/dd/yyyy HH:mm:ss.SSS

I have to consider ms, too.

I tried using joda:

String sDateStart = "2015/10/14 22:37:28.648";
String sDateFiish = "2015/10/14 22:39:13.573";

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

Date dt1 = format.parse(sDateFiish);
Date dt2 = format.parse(sDateStart);


DateTime start = new DateTime(dt1);
DateTime finish = new DateTime(dt2);

System.out.println(Days.daysBetween(start, finish));
System.out.println(Minutes.minutesBetween(start, finish));
System.out.println(Seconds.secondsBetween(start, finish));

Is there any method to consider the ms?

you date String is of format `YYYY-MM-DD` and your trying to convert it to `SimpleDateFormat("MM/dd/yyyy..` ???? — Nishanth Matha, Oct 14 '15 at 23:07
I followed this guide: http://www.mkyong.com/java/how-to-calculate-date-time-difference-in-java/ — harry-potter, Oct 14 '15 at 23:10
A better question would be to understand what do you mean by "Is there any method to consider the ms?" — Acewin, Oct 14 '15 at 23:10
What was the Joda Time Library is now the Java 8 Date-Time API. You can do with the `java.time.*` platform classes what you used to do with Joda. — scottb, Oct 14 '15 at 23:11

[Here's the javadoc.](http://www.joda.org/joda-time/apidocs/org/joda/time/Duration.html) — Sotirios Delimanolis, Oct 14 '15 at 23:21
hehe its always interesting when people do not go through javadocs properly — Acewin, Oct 14 '15 at 23:22

If you are using Java API itself. In Date class we have getTime method which gives time in millisecond

getTime() Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

System.out.println((long)(dt1.getTime() - dt2.getTime()));

If you wanna continue using Joda Time API use Duration. as mentioned by Sotirios Delimanolis
