Help with login and register program?

Hi,

I am creating a login and register system for my program but I don't really know what file format I would use to save the registration details so that I can store them for the login. Any guidance?

Thanks,

It depends on what you're trying to achieve but if you're storing the credentials locally I would suggest sqlite.

Forgot to say that I don't want an external library :/

Nothing whatsoever to do with AWT/Swing. Moving to New to Java
