以下示例程序旨在说明WeekFields.getMinimalDaysInFirstWeek()方法:
程序1:
// Java program to demonstrate
// WeekFields.getMinimalDaysInFirstWeek() method
import java.time.DayOfWeek;
import java.time.temporal.WeekFields;
public class GFG {
public static void main(String[] args)
{
// create WeekFields
WeekFields weekFields
= WeekFields.of(DayOfWeek.SATURDAY, 2);
// apply getMinimalDaysInFirstWeek()
int noOfDays
= weekFields.getMinimalDaysInFirstWeek();
// print results
System.out.println("Minimal number of days"
+ " in the first week:"
+ noOfDays);
}
}
输出:
Minimal number of days in the first week:2
程序2:
// Java program to demonstrate
// WeekFields.getMinimalDaysInFirstWeek() method
import java.time.temporal.WeekFields;
import java.util.Locale;
public class GFG {
public static void main(String[] args)
{
Locale locale = new Locale("EN", "INDIA");
// create WeekFields
WeekFields weekFields
= WeekFields.of(locale);
// apply getMinimalDaysInFirstWeek()
int noOfDays
= weekFields.getMinimalDaysInFirstWeek();
// print results
System.out.println("Minimal number of days"
+ " in the first week:"
+ noOfDays);
}
}
输出:
Minimal number of days in the first week:1
