java计算时间差精确到毫秒

 private static void getBetweenTime(String start, String type)
   throws ParseException {
  SimpleDateFormat dfs = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
  long between = 0;
  try {
   java.util.Date begin = dfs.parse(start);
   java.util.Date end = dfs.parse(getCurrentTime());
   between = (end.getTime() - begin.getTime());// 得到两者的毫秒数
  } catch (Exception ex) {
   ex.printStackTrace();
  }
  long day = between / (24 * 60 * 60 * 1000);
  long hour = (between / (60 * 60 * 1000) - day * 24);
  long min = ((between / (60 * 1000)) - day * 24 * 60 - hour * 60);
  long s = (between / 1000 - day * 24 * 60 * 60 - hour * 60 * 60 - min * 60);
  long ms = (between - day * 24 * 60 * 60 * 1000 - hour * 60 * 60 * 1000
    - min * 60 * 1000 - s * 1000);
  System.out.println(day + "天" + hour + "小时" + min + "分" + s + "秒" + ms
    + "毫秒");
 }
