示例 3

import java.util.*;
public class CalendargetactualminimumExample3 {
   public static void main(String[] args) {
      // create a calendar
      Calendar cal = Calendar.getInstance();
      // get minimum value of passed fields and stores in corresponding parameter.
      int day1 = cal.getActualMinimum(Calendar.DAY_OF_WEEK_IN_MONTH);
      System.out.println("Minimum  value for DAY_OF_WEEK_IN_MONTH  is :" + day1);
      int day2 = cal.getActualMinimum(Calendar.DAY_OF_MONTH);
        System.out.println("Minimum  value for DAY_OF_MONTH is :" + day2);
        int dt = cal.getActualMinimum(Calendar.DATE);
        System.out.println("Minimum value for  DATE is :" + dt);
   }
}
