Does it have any sense to make a setter method private (in a real program)?
Nobody will be able to change that private variables, because of: the private setter method also uncallable.
(In this task we had to make the setter method private.)
Private setter method?...

Have a look at the Singleton design pattern. Will be used quite often in the upcoming tasks.

Thanks, but I'm sorry, i don't know what means "singleton" - so i don't understand anything from this article. At my level this article is too difficult for me.

In short the singletons purpose is to make sure only one object of a class gets instanciated. For example you can use that for program settings. The private constructor doesn't allow creating objects. For that you need to use a static method. That one checks if there already is an instance and either returns that instance or a new object.
I have forgotten when that pattern first gets introduced here but it is not far away anymore.
