提问by Casebash
I am using getResourceAsStreamto access a local file. What encoding does it assume the file is?
我正在使用getResourceAsStream访问本地文件。它假设文件是什么编码？

InputStreams don't have encodings. They're just streams of bytes. Readers are for text with an encoding. You can create a Readerwith a specific charset from an InputStreamlike this:
InputStreams 没有编码。它们只是字节流。Reader用于带有编码的文本。您可以Reader从InputStream这样的特定字符集创建一个：
Reader reader = new InputStreamReader(inputStream, "UTF-8");
If you're using a charset that's guaranteed to be supported on all Java platforms like UTF-8, you can avoid having to deal with impossible UnsupportedEncodingExceptions by using a constant from Guava's Charsetsclass like Charsets.UTF_8.
如果您使用有保证的所有Java平台，如UTF-8将要支持的字符集，你可不必处理不可能UnsupportedEncodingException通过利用从常数s番石榴的Charsets象类Charsets.UTF_8。

I do not know how to use encoding in getResourceStream(), generally you can query the file.encodingproperty or Charset.defaultCharset()to find the current default encoding.it is better to explicitly specify the desired encoding (i.e. "UTF-8") in the code. In this way, it will work even across different platforms.
我不知道如何在 中使用编码getResourceStream()，一般可以查询file.encoding属性或Charset.defaultCharset()查找当前默认编码。最好在代码中明确指定所需的编码（即“UTF-8”）。这样，它甚至可以跨不同平台工作。
Also how to read a file , you can look at this post How to create a Java String from the contents of a fileJon Skeet's answer.
还有如何读取文件，您可以查看这篇文章 如何从文件内容创建 Java 字符串Jon Skeet 的回答。
