|

* symbols in canonical order from the largest date or time unit to the smallest,

* which can be expressed with the following regular expression:
|
||||
* {@snippet :

|

* "Q{0,5}" + // Quarter

* "s{0,2}" + // Second of Minute
|

* "[vz]{0,4}" // Zone
|

* }
|
||||
* All pattern symbols are optional, and each pattern symbol represents a field,
|
||||
* for example, 'M' represents the Month field. The number of the pattern symbol letters follows the
|
||||
* same presentation, such as "number" or "text" as in the <a href="#patterns">Patterns for
|
||||
* Formatting and Parsing</a> section. Other pattern symbols in the requested template are

* <p>

* <a href="https://www.unicode.org/reports/tr35/tr35-dates.html#availableFormats_appendItems">
|
||||
* Unicode LDML specification</a>. For example, the formatter created from the requested template
|
||||
* {@code yMMM} will format the date '2020-06-16' to 'Jun 2020' in the {@link Locale#US US locale}.
|
||||
* <p>
|
||||
* The locale is determined from the formatter. The formatter returned directly by

* this method uses the {@link Locale#getDefault() default FORMAT locale}.
|
||||
* The locale can be controlled using {@link DateTimeFormatter#withLocale(Locale) withLocale(Locale)}
|
||||
* on the result of this method.
|

* <p>
|

* The returned formatter has no override zone.

* "s{0,2}" + // Second of Minute
|

* "[vz]{0,4}" // Zone
|

* }
|
||||
* All pattern symbols are optional, and each pattern symbol represents a field,
|
||||
* for example, 'M' represents the Month field. The number of the pattern symbol letters follows the
|
||||
* same presentation, such as "number" or "text" as in the
