类名称：DateTimeFormatter

DateTimeFormatter介绍

[英]Controls the printing and parsing of a datetime to and from a string.

This class is the main API for printing and parsing used by most applications. Instances of this class are created via one of three factory classes:

  • DateTimeFormat - formats by pattern and style
  • ISODateTimeFormat - ISO8601 formats
  • DateTimeFormatterBuilder - complex formats created via method calls

An instance of this class holds a reference internally to one printer and one parser. It is possible that one of these may be null, in which case the formatter cannot print/parse. This can be checked via the #isPrinter()and #isParser() methods.

The underlying printer/parser can be altered to behave exactly as required by using one of the decorator modifiers:

  • #withLocale(Locale) - returns a new formatter that uses the specified locale
  • #withZone(DateTimeZone) - returns a new formatter that uses the specified time zone
  • #withChronology(Chronology) - returns a new formatter that uses the specified chronology
  • #withOffsetParsed() - returns a new formatter that returns the parsed time zone offset
    Each of these returns a new formatter (instances of this class are immutable).

The main methods of the class are the printXxx and parseXxx methods. These are used as follows:

// print using the defaults (default locale, chronology/zone of the datetime) 
String dateStr = formatter.print(dt); 
// print using the French locale 
String dateStr = formatter.withLocale(Locale.FRENCH).print(dt); 
// print using the UTC zone 
String dateStr = formatter.withZone(DateTimeZone.UTC).print(dt); 
// parse using the Paris zone 
DateTime date = formatter.withZone(DateTimeZone.forID("Europe/Paris")).parseDateTime(str);
