package com.iowiki;
import java.util.*;
public class CalendarDemo {
   public static void main(String[] args) {
      // create a calendar
      Calendar cal = Calendar.getInstance();
      // print current first day of the week
      int day = cal.getFirstDayOfWeek();
      System.out.println("Current first day of the week:" + day);
      // set first day of the week as something else
      cal.setFirstDayOfWeek(Calendar.WEDNESDAY);
      // print altered first day of the week
