如何在 Java 中计算时间跨度并格式化输出? [英] How can I calculate a time span in Java and format the output?

问题描述

我想取两次(自纪元以来的秒数)并以如下格式显示两者之间的差异:

• 2 分钟
• 1 小时 15 分钟
• 3 小时 9 分钟
• 1 分钟前
• 1 小时 2 分钟前

我怎样才能做到这一点??

解决方案

您也可以使用 Joda-Time 执行此操作.使用 Period代表一个时期.要在所需的人类表示中格式化句点，请使用 PeriodFormatter 您可以通过 PeriodFormatterBuilder.

这是一个启动示例:

DateTime myBirthDate = new DateTime(1978, 3, 26, 12, 35, 0, 0);DateTime now = new DateTime();期间期间=新期间(myBirthDate，现在)；PeriodFormatter 格式化程序 = new PeriodFormatterBuilder().appendYears().appendSuffix("年,","年,").appendMonths().appendSuffix("月,","月,").appendWeeks().appendSuffix("周,","周,").appendDays().appendSuffix(" day, ", " days, ").appendHours().appendSuffix("小时,","小时,").appendMinutes().appendSuffix("minute,","minutes,").appendSeconds().appendSuffix("秒","秒").printZeroNever().toFormatter();String elapsed = formatter.print(period);System.out.println(elapsed + " ago");

更加简洁明了，不是吗?

现在打印出来

<前>32年1个月1周5天6小时56分24秒前

I want to take two times (in seconds since epoch) and show the difference between the two in formats like:

• 2 minutes
• 1 hour, 15 minutes
• 3 hours, 9 minutes
• 1 minute ago
• 1 hour, 2 minutes ago

How can I accomplish this??

解决方案

^{Since everyone shouts "YOODAA!!!" but noone posts a concrete example, here's my contribution.}

You could also do this with Joda-Time. Use Period to represent a period. To format the period in the desired human representation, use PeriodFormatter which you can build by PeriodFormatterBuilder.

Here's a kickoff example:

DateTime myBirthDate = new DateTime(1978, 3, 26, 12, 35, 0, 0);
DateTime now = new DateTime();
Period period = new Period(myBirthDate, now);

PeriodFormatter formatter = new PeriodFormatterBuilder()
    .appendYears().appendSuffix(" year, ", " years, ")
    .appendMonths().appendSuffix(" month, ", " months, ")
    .appendWeeks().appendSuffix(" week, ", " weeks, ")
    .appendDays().appendSuffix(" day, ", " days, ")
    .appendHours().appendSuffix(" hour, ", " hours, ")
    .appendMinutes().appendSuffix(" minute, ", " minutes, ")
    .appendSeconds().appendSuffix(" second", " seconds")
    .printZeroNever()
    .toFormatter();

String elapsed = formatter.print(period);
System.out.println(elapsed + " ago");

Much more clear and concise, isn't it?

This prints by now

32 years, 1 month, 1 week, 5 days, 6 hours, 56 minutes, 24 seconds ago
