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

问题描述

我查看过以前的问题，但没有人得到我想要的答案。
如何将StopWatch方法的毫秒转换为分钟和秒？
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();

停止观看。我后来有

  watch.getTime();

返回毫秒。我希望它能在秒和分钟内返回。我该怎么做呢？ 我正在寻找一种方法来实现它，而不是乘以/除以1000，而是一种方法，可以使整个计算更具可读性，更不容易出错。

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 。您可以这样使用它：

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

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