  • And no, I have not tested it because I don’t know how I’m actually supposed to do that.

    depends on what you backup and how.

    if it’s just “dumb” files (videos, music pictures etc.), just retrieve them from your backups and check if you can open the files.

    complex stuff? probably try to rebuild the complex stuff from a backup and check if it works as expected and is in the state you expect it to be in. how to do that really depends on the complex stuff.

    i’d guess for most people it’s enough to make sure to backup dumb files and configurations, so they can rebuild their stuff rather than being able to restore a complex system in exactly the same state it was in before bad things happened.




  • Access control and offering a sound interface.

    You don’t need getters and setters if every attribute is public, but you might want to make sure attributes are accessed in a specific way or a change to an object has to trigger something, or the change has to wait until the object is done with something. Java just has tools to enforce a user of your objects to access its attributes through the methods you designed for that. It’s a safeguard against unintended side effects, to only open up inner workings of a class as littles as necessary.

    In a language without something like private attributes you’d have to account for far more ways someone might mutate the state of objects created by your code, it opens you up to far more possible mistakes.
