Java代码 
- import java.util.Calendar;
- import java.util.TimeZone;
- public class Test1 {
- public static void main(String[] args) {
- //指定东八区，即北京时间
- Calendar cc = Calendar.getInstance(TimeZone.getTimeZone("GMT+8"));
- int year = cc.get(Calendar.YEAR);
- //月份是从0开始计数的，所以此处进行加1
- int month = cc.get(Calendar.MONTH)+1;
- int day = cc.get(Calendar.DAY_OF_MONTH);
- int hour_8 = cc.get(Calendar.HOUR);//8小时制
- int hour_24 = cc.get(Calendar.HOUR_OF_DAY);//24小时制
- int minute = cc.get(Calendar.MINUTE);
- int second = cc.get(Calendar.SECOND);
- //需减一（西方一周的第一天是周日）
- int weekday = cc.get(Calendar.DAY_OF_WEEK)-1;
- //8小时制输出
- System.out.println(year+"-"+month+"-"+day+" "+hour_8+":"+minute+":"+second+" 星期"+weekday);
- //24小时制输出
- System.out.println(year+"-"+month+"-"+day+" "+hour_24+":"+minute+":"+second+" 星期"+weekday);
- }
- }
