regex date validation for yyyyMMdd

Question

I\'m looking for a regex string that will validate dates formatted as yyyyMMdd (no delimiters) and works for leap years. The closest thing I found so far only validates dat

Answer 1

I suggest using the java.text.DateFormat as shown in this page :

public static boolean isValidDateStr(String date) {
    try {
      SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
      sdf.setLenient(false);
      sdf.parse(date);
    }
    catch (ParseException e) {
      return false;
    }
    catch (IllegalArgumentException e) {
      return false;
    }
    return true;
  }
