import java.util.Calendar;

public class CalendarTest {

    /**

    public static void main(String[] args) {
        //获得日历对象
        Calendar c = Calendar.getInstance();
//      System.out.println(c.get(Calendar.YEAR));
//      System.out.println(c.get(Calendar.DATE));
        c.setFirstDayOfWeek(Calendar.MONDAY);
        //显示当前的日期和各个分量
        display(c);

        //设置日期和时间
        c.set(2012, 11, 23);
        c.set(Calendar.HOUR, 10);
        c.set(Calendar.MINUTE, 4);
        c.set(Calendar.SECOND, 54);
        System.out.println("更新后的时间：");
        display(c);

        //调整日期和时间
        c.add(Calendar.DATE, 10); //意思是把当前日期加上10天
        c.add(Calendar.HOUR_OF_DAY, 10);//意思是把当前时间加上10个小时

    }

    public static void display(Calendar c){
        String month[]={"1月","2月","3月","4月","5月","6月","7月","8月","9月","10月","11月","12月"};
        String days[]={"星期日","星期一","星期二","星期三","星期四","星期五","星期六"};
        System.out.print("日期：");
        System.out.print(c.get(Calendar.YEAR )+"年");
        System.out.print(month[c.get(Calendar.MONTH)]);
        System.out.print(c.get(Calendar.DATE )+"日 ");
        System.out.println(days[c.get(Calendar.DAY_OF_WEEK)-1]);
        System.out.print("时间：");
