package com.yiibai;

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
