将毫秒转换为分和秒? [英] Converting Milliseconds to Minutes and Seconds?

问题描述

我已经查看了以前的问题，但没有一个答案是我想要的.如何将秒表方法中的毫秒转换为分和秒?我有:

I have looked through previous questions, but none had the answer I was looking for. How do I convert milliseconds from a StopWatch method to Minutes and Seconds? I have:

 watch.start();

启动秒表和

  watch.stop();

停止手表.我后来有

  watch.getTime();

返回毫秒.我希望它在秒和分钟内返回.我该怎么做呢?我正在寻找一种无需乘以/除以 1000 的方法，而是一种使整个计算更具可读性且不易出错的方法.

which returns Milliseconds. I want it to return in Seconds and Minutes. How do I go about doing so? I'm looking for a way to do it without multiplying/dividing by 1000 but rather a method that will make the whole computation more readable and less error-prone.

推荐答案

我建议使用 TimeUnit.你可以这样使用它:

I would suggest using TimeUnit. You can use it like this:

long minutes = TimeUnit.MILLISECONDS.toMinutes(millis);
long seconds = TimeUnit.MILLISECONDS.toSeconds(millis);
