得到当前的时间并添5分钟

//得到当前年月日时分
   SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmm");
   Calendar nowTime = Calendar.getInstance();
   nowTime.add(Calendar.MINUTE, 5);    //当前时间加上五分钟
   String dateTime = dateFormat.format(nowTime.getTime());
   
   //得到当前年月日
   SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
   Calendar c = Calendar.getInstance();
   c.add(Calendar.DATE, 1);                    //当前日期加上一天
   String tomorrowDate = format.format(c.getTime());

备忘：

int numMonth = Integer.parseInt(month);
     if (numMonth < 9) {
      month = "0" + (numMonth + 1);
     } else if (numMonth == 9) {
      month = "10";
     } else {
      month = "" + (numMonth + 1);
     }
     if (day.length() == 1) {
      day = "0" + day;
     }
     if (startHour.length() == 1) {
      startHour = "0" + startHour;
     }
     if (startminute.length() == 1) {
      startminute = "0" + startminute;
     }

     String date = year + month + day + startHour + startminute;
