How to get directory from .jar file into File object?

Question

I have a .jar file and at root of them located a folder. How I can read this folder into java File class?

Answer 1

You can't use File, since this file does not exist independently on the file system. Instead you need getResourceAsStream() to get the contents of the folder, like this:

InputStream in = getClass().getResourceAsStream("/FILENAME.TXT");
BufferedReader input = new BufferedReader(new InputStreamReader(in));
