Java 8 LocalDate won't parse valid date string [duplicate]

Answer 1

No need to specify the format by hand. It’s already built-in.

    final String createdDateStr = "20110920";
    final DateTimeFormatter formatter = DateTimeFormatter.BASIC_ISO_DATE;
    final LocalDate localDate = LocalDate.parse(createdDateStr, formatter);
    System.out.println(localDate);

This outputs:

2011-09-20

Answer 2

An example from the documentation:

LocalDate date = LocalDate.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
String text = date.format(formatter);
LocalDate parsedDate = LocalDate.parse(text, formatter);

You should use "yyyyMMdd" instead of "YYYYMMdd". The difference between Y and y was mentioned here.
