- 如果一年的第4天是星期一,则第1周从第4周开始,而第1至第3周在上一年的最后一周
- 如果一年中的第5天是星期一,则第二周从第5周开始,第1至第4周在第1周
该字段可用于任何日历系统。

以下示例程序旨在说明WeekFields.weekOfWeekBasedYear()方法:
程序1:
// Java program to demonstrate
// WeekFields.weekOfWeekBasedYear() method
import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.temporal.TemporalField;
import java.time.temporal.WeekFields;
public class GFG {
public static void main(String[] args)
{
// create WeekFields
WeekFields weekFields
= WeekFields.of(DayOfWeek.MONDAY, 1);
// apply weekOfWeekBasedYear()
TemporalField weekOfWeekBasedYear
= weekFields.weekOfWeekBasedYear();
// create a LocalDate
LocalDate day = LocalDate.of(2021, 12, 21);
// get week of week for localdate
int wow = day.get(weekOfWeekBasedYear);
// print results
System.out.println("Week of week for "
+ day + ":" + wow);
}
}
输出:
Week of week for 2021-12-21:52
程序2:
// Java program to demonstrate
// WeekFields.weekOfWeekBasedYear() method
import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.temporal.TemporalField;
import java.time.temporal.WeekFields;
public class GFG {
public static void main(String[] args)
{
// create WeekFields
WeekFields weekFields
= WeekFields.of(DayOfWeek.SUNDAY, 1);
// apply weekOfWeekBasedYear()
TemporalField weekOfWeekBasedYear
= weekFields.weekOfWeekBasedYear();
// create a LocalDate
LocalDate day = LocalDate.of(2014, 10, 12);
// get week of week for localdate
int wow = day.get(weekOfWeekBasedYear);
// print results
System.out.println("Week of week for "
+ day + ":" + wow);
}
}
输出:
Week of week for 2014-10-12:42
