Runtime exception while parsing date in linux system (Working fine in windows system)

Question

import java.time.LocalDateTime;

final java.time.format.DateTimeFormatter formatter =
         java.time.format.DateTimeFormatter.ofPattern("E MMM dd HH:mm:ss z yyyy");

final LocalDateTime dateTime1 = LocalDateTime.parse("Fri Sep 14 18:04:03 BST 2018", formatter)

The above code is working fine in Windows system but in Linux system its throwing Runtime exception : java.time.format.DateTimeParseException : Text 'Fri Sep 14 18:16:13 BST 2018' could not be parsed: null

Answer 1

The problem is likely because your Linux system is using a non-English Locale, ie Friday is not named Fri .

Explicitly specify the locale:

DateTimeFormatter.ofPattern("E MMM dd HH:mm:ss z yyyy", Locale.UK);
