// DateTimeFormatterBuilder provides custom way to create a
    // formatter
    // It is Case Insensitive, Nov , nov and NOV will be treated same
    DateTimeFormatter f = new DateTimeFormatterBuilder().parseCaseInsensitive()
            .append(DateTimeFormatter.ofPattern("yyyy-MMM-dd")).toFormatter();
    try {
        LocalDate datetime = LocalDate.parse("2019-DeC-22", f);
        System.out.println(datetime); // 2019-12-22
    } catch (DateTimeParseException e) {
        // Exception handling message/mechanism/logging as per company standard
    }
