What relative path do I need to use in my Java project

Question

I have a structure like this:

src 
  - | com 
       - | company 
               - | Core -> JAVA class 
  - | rules -> text files

Inside Core is a Java class that uses:

BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream(fileName)));

But I can’t figure out which relative path to use. Now I use:

".. \\ .. \\ .. \\ .. \\ rules \\ rule1.txt"

I also tried:

"../../../../rules/rule1.txt"

Where am I wrong?
