如何在Java中将毫秒转换为“X mins x秒”？(How to convert Milliseconds to “X mins, x seconds” in Java?)

当用户在我的程序中开始某些东西时，我想使用System.currentTimeMillis()记录时间。 当他完成时，我将从start变量中减去当前的System.currentTimeMillis() ，并且我想使用诸如“XX小时，XX分钟，XX秒”之类的人类可读格式甚至“XX分钟” ，XX秒“，因为它不太可能会拿一个小时。

最好的方式是做什么？

I want to record the time using System.currentTimeMillis() when a user begins something in my program. When he finishes, I will subtract the current System.currentTimeMillis() from the start variable, and I want to show them the time elapsed using a human readable format such as "XX hours, XX mins, XX seconds" or even "XX mins, XX seconds" because its not likely to take someone an hour.

What's the best way to do this?

使用java.util.concurrent.TimeUnit类：

String.format("%d min, %d sec", TimeUnit.MILLISECONDS.toMinutes(millis), TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)) );

注意： TimeUnit是Java 1.5规范的一部分，但是从Java 1.6开始添加了toMinutes 。

要为值0-9添加前导零，只需执行以下操作：

String.format("%02d min, %02d sec", TimeUnit.MILLISECONDS.toMinutes(millis), TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)) );

如果TimeUnit或toMinutes不受支持（例如在API版本9之前的Android上），请使用以下等式：

int seconds = (int) (milliseconds / 1000) % 60 ; int minutes = (int) ((milliseconds / (1000*60)) % 60); int hours = (int) ((milliseconds / (1000*60*60)) % 24); //etc...

Use the java.util.concurrent.TimeUnit class:

String.format("%d min, %d sec", TimeUnit.MILLISECONDS.toMinutes(millis), TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)) );

Note: TimeUnit is part of the Java 1.5 specification, but toMinutes was added as of Java 1.6.

To add a leading zero for values 0-9, just do:

String.format("%02d min, %02d sec", TimeUnit.MILLISECONDS.toMinutes(millis), TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)) );

If TimeUnit or toMinutes are unsupported (such as on Android before API version 9), use the following equations:

int seconds = (int) (milliseconds / 1000) % 60 ; int minutes = (int) ((milliseconds / (1000*60)) % 60); int hours = (int) ((milliseconds / (1000*60*60)) % 24); //etc...如何在Java中将毫秒转换为“X mins x秒”？(How to convert Milliseconds to “X mins, x seconds” in Java?)
