Как получить список пользователей ?

private List<Person> personList = new ArrayList<Person>();
 
    public void addPerson(Person person){
        personList.add(person);
    }
    public Person getPersons(){
        Iterator iterator = personList.iterator();
        while (iterator.hasNext()){
            iterator.next();
        }
        return (Person) iterator;
    }

@WebServlet(urlPatterns = "/addclientform.jsp")
public class AddClientServlet extends HttpServlet {
 
    private PersonStorage list = new PersonStorage();
 
    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
 
        String name = req.getParameter("name");
        int age = Integer.parseInt(req.getParameter("age"));
        String email = req.getParameter("email");
 
        Person person = new Person(name, age, email);
        list.addPerson(person);
 
        req.getRequestDispatcher("succes.jsp").forward(req, resp);
    }
 
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        req.setAttribute("list", list.getPersons());
        req.getRequestDispatcher("clientList.jsp").forward(req,resp);
    }
}

while (iterator.hasNext()){
            iterator.next();
        }

public List<Person> getPersons(){
        
        return this.personList;
    }
