Java，默认编码 [英] Java, default encoding

问题描述

可能的重复：

jvm的默认编码是什么？

当用于处理文本数据时，Java中的默认字符编码是什么？

我已经浏览了一段时间，我找不到答案（或我没有正确搜索）。我有文本数据，从网页下载。 Java用于此，并使用默认编码来处理一切。我的意思是，在整个过程（下载）没有指定编码，我认为必须有一些默认的。哪一个？谢谢。

解决方案

您可以在应用启动时在命令行中指定默认编码：

  java -Dfile.encoding = UTF8 au.com.objects.MyClass 
  

如果没有指定，则默认值从底层操作系统获得，如上面AlbertoPL解释。

Hello,

what is the default character encoding in Java, when used to process text data?

I have browsed quite a while, however, I cannot find an answer (or I am not searching properly). I have text data, which was downloaded from web pages. Java was used for this, and the default encoding to process everything. I mean, during the whole process (downloading) no encoding was specified, and I assume there must be some default one. Which one? Thank you.

解决方案

you can specify the default encoding on the command line when the app is started:

java -Dfile.encoding=UTF8 au.com.objects.MyClass

If nothing is specified then the default is got from the underlying OS as AlbertoPL explains above.
