package test;import java.util.Calendar;public class CalendarTest {/** * @param args */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：");System.out.print(c.get(Calendar.HOUR)+":");System.out.print(c.get(Calendar.MINUTE)+":");System.out.println(c.get(Calendar.SECOND));} }
