LocalDate and LocalDateTime are immutable date-time objects representing a date and a date and time. To convert String to one of the two Date objects, the provided String must represent a valid date or time according to ISO_LOCAL_DATE or ISO_LOCAL_DATE_TIME. Otherwise, a DateTimeParseException will…
