下面的程序说明了 WeekFields.weekBasedYear() 方法：
方案一：

// Java program to demonstrate
// WeekFields.weekBasedYear() method
  
import java.time.DayOfWeek;
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 weekBasedYear()
        TemporalField weekBasedYear
            = weekFields.weekBasedYear();
  
        // print results
        System.out.println(weekBasedYear);
    }
}

输出：

WeekBasedYear[WeekFields[MONDAY, 1]]

方案二：

// Java program to demonstrate
// WeekFields.weekBasedYear() method
  
import java.time.DayOfWeek;
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 weekBasedYear()
        TemporalField weekBasedYear
            = weekFields.weekBasedYear();
  
        // print results
        System.out.println(weekBasedYear);
    }
}

输出：

WeekBasedYear[WeekFields[SUNDAY, 1]]
