Below programs illustrate the WeekFields.getMinimalDaysInFirstWeek() method:
Program 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);    }} |
Output:
Minimal number of days in the first week: 2
Program 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);    }} |
Output:
