总结:时间类Calendar.类代表当前时
Calendar c=Calendar.getInstance();,,Calendar是抽象类。Calendar的构造方法是私有的,API提供了getIntstance方法来创建的对象,
使用该方法获得的Date对象就代表当前系统时间,
package com.aaaaaaaaaaaaaaaaaaaa; import java.util.*; public class time { public static void main(String[] args) { Calendar c = Calendar.getInstance(); int year = c.get(Calendar.YEAR); int month = c.get(Calendar.MONTH) + 1; int date = c.get(Calendar.DATE); int hour = c.get(Calendar.HOUR_OF_DAY); int second = c.get(Calendar.SECOND); int minute = c.get(Calendar.MINUTE); System.out.println("年份:" + year); System.out.println("月份:" + month); System.out.println("日期" + date); System.out.println("小时:" + hour); System.out.println("分钟:" + minute); System.out.println("秒" + second); } } 年份:2013 月份:11 日期30 小时:8 分钟:39 秒51
