java.time.format.DateTimeParseException: Text could not be parsed at index 3

Question

I am using Java 8 to parse the the date and find difference between two dates.

Here is my snippet:

String date1 =\"01-JAN-2017\";
String date2 = \"02-FEB         


        

Answer 1

The following code works. The problem is you are using "JAN" instead of "Jan". DateTimeFormatter does not recognize that it seems. and also change the pattern to "d-MMM-yyyy".

  String date1 ="01-Jan-2017";
  String date2 = "02-Feb-2017";

  DateTimeFormatter df = DateTimeFormatter.ofPattern("d-MMM-yyyy");
  LocalDate  d1 = LocalDate.parse(date1, df);
  LocalDate  d2 = LocalDate.parse(date2, df);

  Long datediff = ChronoUnit.DAYS.between(d1,d2);
