How to sanity check a date in Java [closed]

Answer 1

Building on Aravind's answer to fix the problem pointed out by ceklock in his comment, I added a method to verify that the dateString doesn't contain any invalid character.

Here is how I do:

private boolean isDateCorrect(String dateString) {
    try {
        Date date = mDateFormatter.parse(dateString);
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(date);
        return matchesOurDatePattern(dateString);    //added my method
    }
    catch (ParseException e) {
        return false;
    }
}

/**
 * This will check if the provided string matches our date format
 * @param dateString
 * @return true if the passed string matches format 2014-1-15 (YYYY-MM-dd)
 */
private boolean matchesDatePattern(String dateString) {
    return dateString.matches("^\\d+\\-\\d+\\-\\d+");
}
