Method Detail

pattern
public static DateTimeFormatter pattern(String pattern)
Creates a formatter using the specified pattern.This method will create a formatter based on a simple pattern of letters and symbols. For example,
d MMM yyyy
will format 2008-12-03 as '3 Dec 2008'.The returned formatter will use the default locale, but this can be changed using
DateTimeFormatter.withLocale(Locale)
.All letters 'A' to 'Z' and 'a' to 'z' are reserved as pattern letters. The following pattern letters are defined:
Symbol Meaning Presentation Examples ------ ------- ------------ ------- y year year 2004; 04 D day-of-year number 189 M month-of-year month July; Jul; 07 d day-of-month number 10 Q quarter-of-year number 3 q month-of-quarter number 2 x week-based-year year 1996 w week-of-week-based-year number 27 e day-of-week number 2 E day-of-week text Tuesday; Tue 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/fraction 0 k clock-hour-of-am-pm (1-24) number 0 H hour-of-day (0-23) number/fraction 0 m minute-of-hour number/fraction 30 s second-of-minute number/fraction 55 S milli-of-second number/fraction 978 n nano-of-second number/fraction 987654321 I time-zone ID zoneID America/Los_Angeles z time-zone name text Pacific Standard Time; PST Z zone-offset offset -0800; -08:00; f make next a fraction fraction modifier .123 p pad next pad modifier 1 ' escape for text delimiter '' single quote literal ' [ optional section start ] optional section end
The count of pattern letters determine the format.
Text: If the number of pattern letters is 4 or more, the full textual form is used as per
DateTimeFormatterBuilder.TextStyle.FULL
. Otherwise a short form is used, as perDateTimeFormatterBuilder.TextStyle.SHORT
.Number: If the count of letters is one, then the value is printed using the minimum number of digits and without padding as per
DateTimeFormatterBuilder.appendValue(DateTimeFieldRule)
. Otherwise, the count of digits is used as the width of the output field as perDateTimeFormatterBuilder.appendValue(DateTimeFieldRule, int)
.Fraction modifier: Modifies the pattern that immediately follows to be a fraction. All fractional values must use the 'f' prefix to ensure correct parsing. The fraction also outputs the decimal point. If the count of 'f' is one, then the fractional value has the exact number of digits defined by the count of the value being output. If the count of 'f' is two or more, then the fractional value has the a minimum number of digits defined by the count of the value being output and a maximum output of nine digits.
For example, 'ssffnnn' outputs the second followed by 3-9 digits of the nanosecond, while 'mmfss' outputs the minute followed by exactly 2 digits representing the second.
Year: The count of letters determines the minimum field width below which padding is used. If the count of letters is two, then a
reduced
two digit form is used. For printing, this outputs the rightmost two digits. For parsing, this will parse using the base value of 2000, resulting in a year within the range 2000 to 2099 inclusive. If the count of letters is less than four (but not two), then the sign is only output for negative years as perDateTimeFormatterBuilder.SignStyle.NORMAL
. Otherwise, the sign is output if the pad width is exceeded, as perDateTimeFormatterBuilder.SignStyle.EXCEEDS_PAD
Month: If the count of letters is 3 or greater, use the Text rules above. Otherwise use the Number rules above.
ZoneID: 'I' outputs the zone id, such as 'Europe/Paris'.
Offset: 'Z' outputs offset without a colon, without seconds and '+0000' as the text for UTC. 'ZZ' outputs the offset with a colon, without seconds and '+00:00' as the text for UTC. 'ZZZ' outputs offset without a colon, with seconds and 'Z' as the text for UTC (ISO-8601 style). 'ZZZZ' outputs the offset with a colon, with seconds and 'Z' as the text for UTC (ISO-8601 style).
Zone names: Time zone names ('z') cannot be parsed.
Optional section: The optional section markers work exactly like calling
DateTimeFormatterBuilder.optionalStart()
andDateTimeFormatterBuilder.optionalEnd()
.Pad modifier: Modifies the pattern that immediately follows to be padded with spaces. The pad width is determined by the number of pattern letters. This is the same as calling
DateTimeFormatterBuilder.padNext(int)
.For example, 'ppH' outputs the hour-of-day padded on the left with spaces to a width of 2.
Any unrecognized letter will be output directly. However, since these are reserved, that may change in future versions. Any non-letter character, other than '[', ']' and the single quote will be output directly. 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.
The pattern string is similar, but not identical, to
SimpleDateFormat
. SimpleDateFormat pattern letters 'G' and 'W' are not available. Pattern letters 'x', 'Q', 'q', 'e', 'n', 'I', 'f' and 'p' are added. Letters 'y', 'z' and 'Z' have some differences.- Parameters:
pattern
- the pattern to use, not null- Returns:
- the formatter based on the pattern, never null
- Throws:
IllegalArgumentException
- if the pattern is invalid- See Also:
