I wonder is it possible to parse clock time hour:minute:second in Java 8?

e.g.

final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss");
final String str = "12:22:10";
final LocalDateTime dateTime = LocalDateTime.parse(str, formatter);

I tried but get this exception:

Exception in thread "main" java.time.format.DateTimeParseException: Text '12:22:10' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {},ISO resolved to 12:22:10 of type java.time.format.Parsed

  • @Diti Don't think it's the same issue. The link you have provided is parsing a bare date without time. Where as my issue is parsing bare time without date. – Kaizar Laxmidhar Oct 05 '16 at 09:34

    Fundamentally, it's the same issue: you're trying to parse into a `LocalDateTime` but you have no date, so which date is supposed to be parsed? Parse into a `LocalTime` instead, that will work. – Tunaki Oct 05 '16 at 09:36
  • @Tunaki@Diti Thanks for clarifying, that works! – Kaizar Laxmidhar Oct 05 '16 at 09:42

LocalTime.parse

Since you only have a time use the LocalTime class. No need to define a formatting pattern in your case.

String str = "12:22:10";
LocalTime time = LocalTime.parse(str);

See that code run live at IdeOne.com.

See Oracle Tutorial for more info.

LocalTime.parse("04:17");
