java - JDK8: unable to parse LocalTime

Question

I managed to parse a String to a LocalDate object:

DateTimeFormatter f1=DateTimeFormatter.ofPattern("dd MM yyyy");
LocalDate d=LocalDate.parse("26 08 1984",f1);
System.out.println(d); //prints "1984-08-26"

But I cannot do the same with LocalTime. This piece of code:

DateTimeFormatter f2=DateTimeFormatter.ofPattern("hh mm");
LocalTime t=LocalTime.parse("11 08",f2); //exception here
System.out.println(t);

Throws a DateTimeParseException:

Exception in thread "main" java.time.format.DateTimeParseException: Text '11 08' could not be parsed: Unable to obtain LocalTime from TemporalAccessor: {MinuteOfHour=8, HourOfAmPm=11},ISO of type java.time.format.Parsed

What am I doing wrong?

Answer 1

If you use a specific format, according to API:

The string must represent a valid time and is parsed using DateTimeFormatter.ISO_LOCAL_TIME.

hh mm 

for 24h must be

HH mm

or for 12h

kk mm

The handled formats must have this conditions:

• Two digits for the hour-of-day. This is pre-padded by zero to ensure two digits.
• A colon
• Two digits for the minute-of-hour. This is pre-padded by zero to ensure two digits.
• If the second-of-minute is not available then the format is complete.
• A colon
• Two digits for the second-of-minute. This is pre-padded by zero to ensure two digits.
• If the nano-of-second is zero or not available then the format is complete.
• A decimal point
• One to nine digits for the nano-of-second. As many digits will be output as required.
