A day-of-week, such as 'Tuesday'.
DayOfWeek is an enum representing the 7 days of the week -
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.
In addition to the textual enum name, each day-of-week has an int value.
The int value follows the ISO-8601 standard, from 1 (Monday) to 7 (Sunday).
It is recommended that applications use the enum rather than the int value
to ensure code clarity.
This enum provides access to the localized textual form of the day-of-week.
Some locales also assign different numeric values to the days, declaring
Sunday to have the value 1, however this class provides no support for this.
See WeekFields for localized week-numbering.
Do not use ordinal() to obtain the numeric representation of DayOfWeek.
Use getValue() instead.
This enum represents a common concept that is found in many calendar systems.
As such, this enum may be used by any calendar system that has the day-of-week
concept defined exactly equivalent to the ISO calendar system.
