Reading Files in Java

Whenever I read a file in java I always have to put the text file in some arbitrary folder. How can I make my program read/writes files from the same folder that its in.

I want this to work so that even if its moved to another folder or computer, it still works.

Yes, I am. Please enlighten me.

I tried ./SetupFileInfo.txt and ../SetupFileInfo.txt and neither worked.
