Java Localtime parse exception

I have a piece of code that works normally and now somehow doesn't work

I am reading a CSV file and an error occurred while reading in the time field in format 4:38

The code I threw the exception is:

LocalTime.parse("4:38",DateTimeFormatter.ofPattern("HH:mm"))

I also tried "H: mm" or "H: m" for the pattern, but it threw the same exception: the text '4:38' could not be resolved at index 0 Any idea why it throws an exception at the number of hours?

I use Java 8

Solution

This mode requires an "H" and an "m"

LocalTime.parse("4:38",DateTimeFormatter.ofPattern("H:m"));

It applies to 4:38 and 14:38
