getResourceAsStream - What encoding is it read as?

I am using开发者_开发技巧 getResourceAsStream to access a local file. What encoding does it assume the file is?

InputStreams don't have encodings. They're just streams of bytes. Readers are for text with an encoding. You can create a Reader with a specific charset from an InputStream like this:

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 Charsets class like Charsets.UTF_8.

I do not know how to use encoding in getResourceStream(), generally you can query the file.encoding property 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.

Also how to read a file , you can look at this post How to create a Java String from the contents of a file Jon Skeet's answer.
