java items list1 to list2

Question

So, I have to transfer the items of my second list to my first list but it isn't working.
Here is my code:

private List<Kaart> gepakt;
 public void addGepakt (Kaart kaart) {
    this.gepakt.add(kaart);
 }

Second list code:

private List<Kaart> speler1gepakt;
public List<Kaart> getSpeler1gepakt() {
    return speler1gepakt;
}

public void setSpeler1gepakt(List<Kaart> speler1gepakt) {
    this.speler1gepakt = speler1gepakt;
}

Adding value to second list:

view.getSpeler1Kaarten()[1].setOnMouseClicked(new EventHandler<javafx.scene.input.MouseEvent>() {
        @Override
        public void handle(javafx.scene.input.MouseEvent event) {
            model.setSelected(view.getSpeler1Kaarten()[1].getImage());
            view.getSpeler1Kaarten()[1].setImage(new Image("WippenGame/View/Images/BlancoKaart.png"));
            model.getSpeler1gepakt().add(model.getSpeler().getKaart(1));
        }
    });

view.getSpeler2Kaart5().setOnMouseClicked(new EventHandler<MouseEvent>() {
        @Override
        public void handle(MouseEvent event) {
            //items of list2 have to go into list1
        }
    });

and here is my problem: when you click on this image, it should transfer the items of list 2 to list 1. I have tried many solutions but none of them seems to work, anyone does have an idea on how to fix this?

If all you want it to copy the items, then just do `list1.addAll(list2)` — Ori Lentz, Mar 14 '16 at 13:26
@LionelRenaux thx, this post really helped me to understand lists better. — TheMightyRoy, Mar 14 '16 at 19:19

I would try either this:

gepackt = (List<Kaart>)speler1gepakt.clone();

or this:

gepackt = new List<Kaart>(speler1gepakt);

I don't have time to test it now, hope it helps!
