java中两个Date类型的数据求时间差

Question

例如： 
12/07/20 08:40:28 
和 
12/07/20 08:32:15 
的时间差以 
0:08:13

请问对于两个Date类型怎么做到呢，越详细越好

Answer 1

public static void main(String[] args) {
   SimpleDateFormat dfs = new SimpleDateFormat("yy/MM/dd hh:mm:ss");
   java.util.Date begin=dfs.parse("12/07/20 08:32:15");
   java.util.Date end = dfs.parse("12/07/20 08:40:28");
   long between=(end.getTime()-begin.getTime())/1000;//除以1000是为了转换成秒

   long day1=between/(24*3600);
   long hour1=between%(24*3600)/3600;
   long minute1=between%3600/60;
   long second1=between%60/60;
   System.out.println(""+day1+"天"+hour1+"小时"+minute1+"分"+second1+"秒");

}
