如何计算Java中的时差? [英] How can I calculate a time difference in Java?

问题描述

我想从 19:00:00 减去两个时间段，比如 16:00:00.是否有任何 Java 函数?结果可以以毫秒、秒或分钟为单位.

I want to subtract two time periods say 16:00:00 from 19:00:00. Is there any Java function for this? The results can be in milliseconds, seconds, or minutes.

推荐答案

String time1 = "16:00:00";
String time2 = "19:00:00";

SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
Date date1 = format.parse(time1);
Date date2 = format.parse(time2);
long difference = date2.getTime() - date1.getTime(); 

差异以毫秒为单位.
