The main date-time classes provide two methods - one for formatting, format DateTimeFormatter formatter , and one for parsing, parse CharSequence text, DateTimeFormatter formatter. The withLocale method returns a new formatter that overrides the locale. The locale affects some aspects of formatting and parsing. For example, the ofLocalizedDate provides a formatter that uses the locale specific date format. The withChronology method returns a new formatter that overrides the chronology. If overridden, the date-time value is converted to the chronology before formatting. During parsing the date-time value is converted to the chronology before it is returned. The withZone method returns a new formatter that overrides the zone. If overridden, the date-time value is converted to a ZonedDateTime with the requested ZoneId before formatting.
