The next example creates localized datetime formats withofPatternandLocale. Main.java import java.time.LocalDateTime; import java.time.format.DateTimeFormatter; import java.util.Locale; void main() { var now = LocalDateTime.now(); String pattern = "EEEE, MMM dd, yyyy HH:mm:ss a"; var dtf1 ...

For example: LocalDate date = LocalDate.now(); String text = date.format(formatter); LocalDate parsedDate = LocalDate.parse(text, formatter); In addition to the format, formatters can be created with desired Locale, Chronology, ZoneId, and DecimalStyle. ...

Subclasses can override this method to clear/reset some cached data that is dependent on parent format settings, for example cached Java format.

For example, a base value of 1980 and a width of 2 will have valid values from 1980 to 2079. During parsing, the text "12" will result in the value 2012 as that is the value within the range where the last two characters are "12". By contrast, parsing the text "1915" will resul...
