Method Detail

pattern

public static DateTimeFormatter pattern(java.lang.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 2011-12-03 as '3 Dec 2011'.

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
  ------  -------                     ------------      -------

   [       optional section start
   ]       optional section end
 

The count of pattern letters determine the format.

Text: The text style is determined based on the number of pattern letters used. Less than 4 pattern letters will use the short form. Exactly 4 pattern letters will use the full form. Exactly 5 pattern letters will use the narrow form.

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(DateTimeRule). Otherwise, the count of digits is used as the width of the output field as per DateTimeFormatterBuilder.appendValue(DateTimeRule, int).

Number/Text: If the count of pattern letters is 3 or greater, use the Text rules above. Otherwise use the Number rules above.

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 per SignStyle.NORMAL. Otherwise, the sign is output if the pad width is exceeded, as per SignStyle.EXCEEDS_PAD

ZoneID: 'I' outputs the zone id, such as 'Europe/Paris'.

Offset X: This formats the offset using 'Z' when the offset is zero. One letter outputs just the hour', such as '+01' Two letters outputs the hour and minute, without a colon, such as '+0130'. Three letters outputs the hour and minute, with a colon, such as '+01:30'. 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 '+01:30:15'.

Offset Z: This formats the offset using '+0000' or '+00:00' when the offset is zero. One or two letters outputs the hour and minute, without a colon, such as '+0130'. Three letters outputs the hour and minute, with a colon, such as '+01:30'.

Zone names: Time zone names ('z') cannot be parsed.

Optional section: The optional section markers work exactly like calling DateTimeFormatterBuilder.optionalStart() and DateTimeFormatterBuilder.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 is an error. 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. Pattern letters 'E' and 'u' are merged. Pattern letters 'G' and 'W' are not available. Pattern letters 'Z' and 'X' are extended. Pattern letter 'y' and 'Y' parse years of two digits and more than 4 digits differently. Pattern letters 'Q', 'q', 'n', 'A', 'N', 'I', 'f' and 'p' are added. Number types will reject large numbers. The pattern is also similar, but not identical, to that defined by the Unicode Common Locale Data Repository.

Returns:
the formatter based on the pattern, not null
Throws:
java.lang.IllegalArgumentException - if the pattern is invalid
