Unable to parse date Apr 15, 2020 12:14:17 AM to LocalDatetime

问题

I am trying to parse Apr 15, 2020 12:14:17 AM to LocalDateTime using

DateTimeFormatter.ofPattern("MMM DD',' YYYY h:mm:ss a")

I am getting exception

回答1:

Try this format having lower case for date and year.

DateTimeFormatter.ofPattern("MMM dd',' yyyy hh:mm:ss a")

回答2:

your format string only contains one hour char. It should be like this:

 DateTimeFormatter.ofPattern("MMM dd, yyyy hh:mm:ss a")

Edit I fixed the format further , making DD and YYYY lowercase. Also you don't need to excape the comma, because it is not actual text.
