Java获取年月日和时分秒

import java.text.SimpleDateFormat;import java.util.Calendar;public class CalendarIntroTest {public static void main(String[] args) {Calendar cal = Calendar.getInstance();int year = cal.get(Calendar.YEAR);int month = cal.get(Calendar.MONTH) + 1; // 0代表1月，11代表12月int day = cal.get(Calendar.DAY_OF_MONTH);int hour = cal.get(Calendar.HOUR);int minute = cal.get(Calendar.MINUTE);int second = cal.get(Calendar.SECOND);// 打印年月日，时分秒System.out.format("%d/%d/%d %d:%d:%d\n",year,month,day,hour,minute,second);// 2013/10/20 2:4:41SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");String currentTime = sdf.format(cal.getTime());System.out.println(currentTime);// 10/20/2013}}
