        int max_day = calndr.getMaximum(Calendar.DAY_OF_WEEK);
  
        // Displaying the results
        System.out.println("The Maximum"
                           + " days: " + max_day);
    }
}

例2 :

// Java code to illustrate
// getMaximum() method
  
import java.util.*;
  
public class Calendar_Demo {
    public static void main(String args[])
    {
  
        // Creating a calendar
        Calendar calndr = new GregorianCalendar(2018, 6, 10);
  
        // Getting the required months

                           + calndr.get(Calendar.MONTH));
  
        // Getting the lowest maximum month
        int max_month = calndr.getMaximum(Calendar.MONTH);
