用Calendar类来获取当前的时间

代码：

import java.util.Calendar;public class CalendarDemo {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stub        Calendar c=Calendar.getInstance();        int year=c.get(Calendar.YEAR);        int month=c.get(Calendar.MONTH);        int day=c.get(Calendar.DAY_OF_MONTH);        int week=c.get(Calendar.DAY_OF_WEEK);        int hour=c.get(Calendar.HOUR_OF_DAY);        int min=c.get(Calendar.MINUTE);        int second=c.get(Calendar.SECOND);        System.out.println(year+"年"+(month+1)+"月"+day+"日"+",周"+changeWeek(week)+","+hour+":"+min+":"+second);}    private static String changeWeek(int week){    String str="";    switch(week)    {    case 1:    str="日";    break;    case 2:    str="一";    break;    case 3:    str="二";    break;    case 4:    str="三";    break;    case 5:    str="四";    break;    case 6:    str="五";    break;    case 7:    str="六";    break;    }    return str;    }}
