What happens if private nor public is added?

Throughout the entirety of Java Basics, I have never learned to add these. Am I supposed to?

protected is another one. These keywords are for security and tell the program what files can access certain variables or classes. For example, if a class is public, it can be used by any file in the directory. However if you have a private variable, it can only be used in the current class or current file

Here is a great explanation from oracle

Oh I see. Thanks

Those are object oriented programming concepts. Public can be called by any object. But private can be only called by only that particular object within the {}.

I hope that helps.

Thanks for the reply.
