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;
}
}
运行结果：
