What is the default folder for classes extending java.io.Reader and why?

Question

What is the default folder that classes that extend java.io.Reader take input from? For instance, where is "data.txt" supposed to be located in a call to FileReader such as the following?

FileReader fr = new FileReader("data.txt");

In the case of a project I'm currently working on (where I'm using Eclipse and its standard project directory structure), it seems to be the bin-folder. But where's the logic, isn't that folder supposed to contain .class-files and similar don't-touch compiler output?

What is standard practice here, is it really to put folders containing input data under bin/?

该文件在当前工作目录（启动应用程序时所在的目录）中寻找。
