Returns a field to access the week of year based on this WeekFields.
This represents the concept of the count of weeks within the year where weeks start on a fixed day-of-week, such as Monday. This field is typically used with WeekFields#dayOfWeek().
Week one(1) is the week starting on the WeekFields#getFirstDayOfWeek where there are at least WeekFields#getMinimalDaysInFirstWeek() days in the year. Thus, week one may start up to minDays days before the start of the year. If the first week starts after the start of the year then the period before is week zero (0).
For example:<br> - if the 1st day of the year is a Monday, week one starts on the 1st and there is no week zero<br> - if the 2nd day of the year is a Monday, week one starts on the 2nd and the 1st is in week zero<br> - if the 4th day of the year is a Monday, week one starts on the 4th and the 1st to 3rd is in week zero<br> - if the 5th day of the year is a Monday, week two starts on the 5th and the 1st to 4th is in week one<br>
This field can be used with any calendar system.
In the resolving phase of parsing, a date can be created from a year, week-of-year and day-of-week.
In ResolverStyle#STRICT strict mode, all three fields are validated against their range of valid values. The week-of-year field is validated to ensure that the resulting year is the year requested.
In ResolverStyle#SMART smart mode, all three fields are validated against their range of valid values. The week-of-year field is validated from 0 to 54, meaning that the resulting date can be in a different year to that specified.
In ResolverStyle#LENIENT lenient mode, the year and day-of-week are validated against the range of valid values. The resulting date is calculated equivalent to the following three stage approach. First, create a date on the first day of the first week in the requested year. Then take the week-of-year, subtract one, and add the amount in weeks to the date. Finally, adjust to the correct day-of-week within the localized week.
