Parsing time strings like “1h 30min”

Question

Anyone know of a Java library that can parse time strings such as \"30min\" or \"2h 15min\" or \"2d 15h 30min\" as milliseconds (or some kind of Duration object). Can Joda-T

Answer 1

Duration parsing is now included in Java 8. Use standard ISO 8601 format with Duration.parse.

Duration d = Duration.parse("PT1H30M")

You can convert this duration to the total length in milliseconds. Beware that Duration has a resolution of nanoseconds, so you may have data loss going from nanoseconds to milliseconds.

long milliseconds = d.toMillis();

The format is slightly different than what you describe but could be easily translated from one to another.
