Cannot parse date with LocalDateTime

Question

I'm trying to parse a date string using Java8 LocalDateTime without any success.

The exception is: DateTimeParseException: Text '28-APR-2015 01:25:00 PM' could not be parsed at index 3

The string to parse is: 28-APR-2015 01:25:00 PM and the pattern I'm currently using is dd-LLL-yyyy hh:mm:ss a

Where am I wrong?

Thank you

Adding example code:

String text = "28-APR-2015 01:25:00 PM";
DateTimeFormatter fromatter = DateTimeFormatter.ofPattern("dd-LLL-yyyy hh:mm:ss a");
try {
        String out = LocalDateTime.parse(text, formatter)
        System.out.println(out);
    } catch (DateTimeParseException e) {
        e.printStackTrace();
    }

Solved using the response from @Florin using:

    DateTimeFormatter tertiaryFormatter = new DateTimeFormatterBuilder()
        .parseCaseInsensitive().parseLenient().appendPattern("dd-LLL-yyyy hh:mm:ss a").toFormatter();

Can you include a short but complete example demonstrating the problem? — Jon Skeet, Jan 12 '16 at 18:05
I've managed to reproduce this; I think you want `MMM` rather than `LLL` (although the docs aren't clear on what `L` means); but that's case-sensitive so you'd still need `Apr` rather than `APR`. Still working on how to make it case-insensitive... — Jon Skeet, Jan 12 '16 at 18:11
What does it mean "without any success"? Do you have any error? — Dzianis Yafimau, Jan 12 '16 at 18:22
You could create a more permissive DateTimeFormatter class instead of relying on the defaults. For instance: DateTimeFormatter formatter = new DateTimeFormatterBuilder() .parseCaseInsensitive() .parseLenient() .appendPattern("dd-LLL-yyyy hh:mm:ss a") .toFormatter() — Florin, Jan 12 '16 at 18:46

MMM in English will be Apr

LLL in English will be 4

Please run this snippet - it will explain you a lot:

    asList("MMM", "LLL").forEach(ptrn
            -> System.out.println(ptrn + ": " + ofPattern(ptrn, Locale.ENGLISH).format(Month.APRIL))
    );
    Locale.setDefault(Locale.ENGLISH);
    String textM = "28-Apr-2015 01:25:00 PM";
    DateTimeFormatter formatterM = DateTimeFormatter.ofPattern("dd-MMM-yyyy hh:mm:ss a");
    System.out.println(LocalDateTime.parse(textM, formatterM));

    String textL = "28-4-2015 01:25:00 PM";
    DateTimeFormatter formatterL = DateTimeFormatter.ofPattern("dd-LLL-yyyy hh:mm:ss a");
    System.out.println(LocalDateTime.parse(textL, formatterL));

If you need to use APR then you need to build your own DateTimeFormatter using DateTimeFormatterBuilder and set parseCaseInsensitive option.

The problem is because of your time pattern issue. you need make sure your time format could matching with the pattern.
