日期在Java中的不同语言环境中显示？

Question

在java中如何在不同的语言环境中显示日期（例如俄语）。

Answer 1

Something like:

Locale locale = new Locale("ru","RU");
DateFormat full = DateFormat.getDateInstance(DateFormat.LONG, locale);
out.println(full.format(new Date()));

Should do the trick. However, there was a problem of Russian Date formatting in jdk1.5

The deal with Russian language is that month names have different suffix when they are presented stand-alone (ie in a list or something) and yet another one when they are part of a formatted date. So, even though March is "Март" in Russian, correctly formatted today's date would be: "7 Март а 2007 г."

Let's see how JDK formats today's date: 7 Март 2007 г. Clearly wrong.

Answer 2

Use SimpleDateFormat constructor which takes locale. You need to first check if JDK supports the locale you are looking for, if not then you need to implement that.

Answer 3

Use the java.text.DateFormat class, you can construct that's configured to a specific Locale.

DateFormat format = DateFormat.getDateInstance(DateFormat.MEDIUM, theLocaleYouWant);
String text = format.format(new Date());
System.out.println(text);

Answer 4

The DateFormat class can help you. As explained in the Javadoc:

To format a date for a different Locale, specify it in the call to getDateInstance().

 DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE); 

So you just need to adapt this code by using the adequate Locale.

Answer 5

使用带有适当时区和语言环境的java.util.Calendar。
