java - 将时间间隔转换为不同语言的文本？

Question

有没有简单的方法将时间间隔（年龄）转换为文本？例如 - 年龄是 25.45 岁。我需要转换为“ 25 年 3 个月 1 天”。问题不是关于数字 25,3,1，而是如何使用正确的形式（复数，变格）将年/月/日翻译成不同的语言。英语似乎很容易硬编码，但其他语言则不然，我更喜欢一些通用的解决方案。

number / English / Czech / ...
1 / day / den
2 / days / dny
5 / days / dnů
...

Answer 1

Joda time 很容易做到这一点。

例如：

public static void main(String[] args) {
  PeriodFormatter daysHoursMinutes = new PeriodFormatterBuilder()
    .appendDays()
    .appendSuffix(" day", " days")
    .appendSeparator(" and ")
    .appendMinutes()
    .appendSuffix(" minute", " minutes")
    .appendSeparator(" and ")
    .appendSeconds()
    .appendSuffix(" second", " seconds")
    .toFormatter();

  Period period = new Period(72, 24, 12, 0);

  System.out.println(daysHoursMinutes.print(period));
  System.out.println(daysHoursMinutes.print(period.normalizedStandard()));
}

将打印：

24 minutes and 12 seconds
3 days and 24 minutes and 12 seconds

JodaTime 可以用它的大多数格式化程序来做到这一点。 以 javadocPeriodFormat为例。

它说：

Controls the printing and parsing of a time period to and from a string.

This class is the main API for printing and parsing used by most applications. Instances of this class are created via one of three factory classes:

PeriodFormat - formats by pattern and style
ISOPeriodFormat - ISO8601 formats
PeriodFormatterBuilder - complex formats created via method calls
An instance of this class holds a reference internally to one printer and one parser. It is possible that one of these may be null, in which case the formatter cannot print/parse. This can be checked via the isPrinter() and isParser() methods.

The underlying printer/parser can be altered to behave exactly as required by using a decorator modifier:

withLocale(Locale) - returns a new formatter that uses the specified locale
This returns a new formatter (instances of this class are immutable).
The main methods of the class are the printXxx and parseXxx methods. These are used as follows:

 // print using the default locale
 String periodStr = formatter.print(period);
 // print using the French locale
 String periodStr = formatter.withLocale(Locale.FRENCH).print(period);

 // parse using the French locale
 Period date = formatter.withLocale(Locale.FRENCH).parsePeriod(str);
