    Ureadable for someone opening the file? Or for someone whoe really ones to read it? If the first one you could serialize it and save it, if the second one, you need to encrypt it. – Aimnox May 27 '16 at 06:57

Encrypt your data in the file for example with AES.

You can look it up here: How to encrypt String in Java

Just chaning the file extension may not help because you can force to open the file in a text editor. In my optinion encryption is the savest way
