How to format a duration in java? (e.g format H:MM:SS)

Question

I'd like to format a duration in seconds using a pattern like H:MM:SS. The current utilities in java are designed to format a time but not a duration.

Answer 1

Use Joda Time and PeriodFormatter.

Joda Time is a much better date/time API than those in Java anyway :)

Answer 2

If you don't want to drag in libraries, it's simple enough to do yourself using a Formatter, or related shortcut eg. given integer number of seconds s:

String.format("%d:%02d:%02d", s/3600, (s%3600)/60, (s%60))

Answer 3

This is going to be one of the new features in java 7

JSR-310
