如何用Java计算时间跨度并格式化输出？
我想用两次时间（从纪元算起，以秒为单位）显示两种格式之间的差异，如：如何用Java计算时间跨度并格式化输出？,java,date,time,formatting,Java,Date,Time,Formatting,我想用两次时间（从纪元算起，以秒为单位）显示两种格式之间的差异，如： 2分钟 1小时15分钟 3小时9分钟 一分钟前 1小时2分钟前 我怎样才能做到这一点呢？我不是Java专家，但你可以做t1-t2=t3（以秒为单位），然后除以60，得到分钟，再除以60，得到秒。然后，只需计算出您需要多少个部门 希望能有帮助。我总是从一开始。在Java中处理日期和时间总是“有趣”的，但Joda Time可以减轻压力 他们有间隔和持续时间课程，完成了你所寻找的一半。但不确定它们是否有以可读格式输出的函数。我会

我怎样才能做到这一点呢？我不是Java专家，但你可以做t1-t2=t3（以秒为单位），然后除以60，得到分钟，再除以60，得到秒。然后，只需计算出您需要多少个部门 希望能有帮助。我总是从一开始。在Java中处理日期和时间总是“有趣”的，但Joda Time可以减轻压力 他们有间隔和持续时间课程，完成了你所寻找的一半。但不确定它们是否有以可读格式输出的函数。我会继续找的 HTH这门课可以处理大多数与日期相关的数学。不过，您必须自己获得结果并输出格式。没有一个标准库可以完全满足您的需求，尽管可能有第三方库可以做到这一点
long time1, time2;
time1 = System.currentMillis();
.. drink coffee
time2 = System.currentMillis();
long difference = time2 - time1 // millies between time1 and time2
java.util.Date differneceDate = new Date(difference);
要创建类似“2分钟”的字符串，应使用DateFormatter/DateFormat。您可以在JavaAPI规范（Java.sun.com）中找到关于这方面的更多详细信息 我建议您查看一下好的，在简要阅读了API之后，您似乎可以执行以下操作：-
HTH如果您的时间跨越夏令时（夏季）边界，是否要报告天数 例如，第二天的23:00到23:00始终是一天，但可能是23、24或25小时，具体取决于您是否通过夏令时转换
如果你关心这一点，请确保将其纳入你的选择。是的，唤醒了我的死者，但这是我基于@mtim posted代码的改进实现，因为该线程几乎位于搜索的顶部，所以我正在与sleepy hollow混在一起
