JScrollPane scrolllable list

Question

I'm trying to set up a scroll bar for which you can always scroll. Here is what I have:

public static JScrollPane scrollList(){
    JScrollPane scrollList = new JScrollPane(list);
    scrollableList.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
    
    return scrollList;
    
}

Problem is that I can only scroll if the list is long and I want to be able to scroll even if empty.
