// 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

public class GFG {
    public static void main(String[] args)

        Locale locale = new Locale("EN", "INDIA");

        // create WeekFields

            = WeekFields.of(locale);

        // apply getMinimalDaysInFirstWeek()
        int noOfDays
            = weekFields.getMinimalDaysInFirstWeek();

        // print results
        System.out.println("Minimal number of days"
                           + " in the first week: "
