I was writing a simple code on iterators, when I started to get this error. It says that ListIterator does not take parameters but I think it does, so what’s wrong

It seems to work fine for String type but not for wrapper classes, what is the reason behind it

import java.util.*;
public class ListIterator {
    public static void main(String []argv) {
        List<Integer> list = new ArrayList<>();
        list.add(10);
        list.add(30);
        list.add(20);
        ListIterator<Integer> it = list.listIterator();
        while (it.hasNext()) {
            System.out.print(it.next()+" ");
        }
    }
}
