The Local Date date = Local Date.now(); Date Time Formatter formatter = Date Time Pattern("yyyy MM dd"); String text = date.format(formatter); Local Date parsed Date = Local Date.parse(text, formatter); Symbol Meaning Presentation Examples ------ ------- ------------ ------- G era text AD; Anno Domini; A u year year 2004; 04 y year-of-era year 2004; 04 D day-of-year number 189 M/L month-of-year number/text 7; 07; Jul; July; J d day-of-month number 10 Q/q quarter-of-year number/text 3; 03; Q3; 3rd quarter Y week-based-year year 1996; 96 w week-of-week-based-year number 27 W week-of-month number 4 E day-of-week text Tue; Tuesday; T e/c localized day-of-week number/text 2; 02; Tue; Tuesday; T F week-of-month number 3 a am-pm-of-day text PM h clock-hour-of-am-pm (1-12) number 12 K hour-of-am-pm (0-11) number 0 k clock-hour-of-am-pm (1-24) number 0 H hour-of-day (0-23) number 0 m minute-of-hour number 30 s second-of-minute number 55 S fraction-of-second fraction 978 A milli-of-day number 1234 n nano-of-second number 987654321 N nano-of-day number 1234000000 V time-zone ID zone-id America/Los_Angeles; Z; - z time-zone name zone-name Pacific Standard Time; PST O localized zone-offset offset-O GMT 8; GMT ; UTC-; X zone-offset 'Z' for zero offset-X Z; -08; -0830; -; -083015; -; x zone-offset offset-x 0000; -08; -0830; -; -083015; -; Z zone-offset offset-Z 0000; -0800; -; p pad next pad modifier 1 ' escape for text delimiter '' single quote literal ' [ optional section start ] optional section end # reserved for future use reserved for future use .

Pattern letters 'L', 'c', and 'q' specify the stand-alone form of the text styles.

During parsing the date-time value is converted to the chronology before it is returned.

The output will be the corresponding localized offset text if the offset is zero. For example, 'pp H' outputs the hour-of-day padded on the left with spaces to a width of 2. Any non-letter character, other than '[', ']', '', '#' and the single quote will be output directly.

Five letters outputs the hour, minute, with optional second if non-zero, with colon. Despite this, it is recommended to use single quotes around all characters that you want to output directly to ensure that future changes do not break your application. First, the text is parsed using the layout defined by the formatter, producing a , by validating, combining and simplifying the various fields into more useful ones. Four of these perform both the parse and resolve phases.

Zone names: This outputs the display name of the time-zone ID.

If the count of letters is one, two or three, then the short name is output.

Four letters outputs the hour and minute and optional second, without a colon, such as ' 013015'.

Five letters outputs the hour and minute and optional second, with a colon, such as ' '. Pattern letter 'X' (upper case) will output 'Z' when the offset to be output would be zero, whereas pattern letter 'x' (lower case) will output ' 00', ' 0000', or ' '.

Four letters outputs the full form, which is localized offset text, such as 'GMT, with 2-digit hour and minute field, optional second field if non-zero, and colon, for example 'GMT '. Offset Z: This formats the offset based on the number of pattern letters.

One, two or three letters outputs the hour and minute, without a colon, such as ' 0130'.

If the count of letters is four, then the full name is output. Offset X and x: This formats the offset based on the number of pattern letters.

One letter outputs just the hour, such as ' 01', unless the minute is non-zero in which case the minute is also output, such as ' 0130'.

The fifth method, parameter allows the set of fields that will be resolved to be filtered before resolving starts.
