Beginners question: changeable string but saving all "entries"

Question

This is really beginners level and naive(!!!!) programming, please think simple. Learning with BlueJ (not voluntarily, that's my Prof's choice)
public class WikiEntry {
...
private String autor;
private int version;
// left out quite a bit here
public void getAuthor (String newAutor) {
autor = newAutor;
}
//another method left out that let's me change the article and adds a plus one to the int version
}
What I would love to do:
To be able to change the Autor (that already works) but it would be awesome, if it could also safe/store/collect all the Autor Strings in a list automatically. Does that work? Like every time the Autor gets changed it creates a new entry for a list. No need to change the list or to reset or anything else.
Thank you very much for your help, I really appreciate helpful answers on this probably very basic problem...

Answer 1

I have used a HashSet because I think you should not store every author. Only unique authors.

Answer 2

Yup, that's a better implementation, didn't think on that

Answer 3

Thank you very much, Denise. It works beautifully :)

Answer 4

I think what you need is a static list. This is a basic implementation of what you want:
