    cursorList.add("Element3");

    ListIterator iterator = cursorList.listIterator();
    iterator.next(); // cursor now between 0th and 1st element
    iterator.add("Element2.5"); // adds this between 0th and 1st element

    System.err.println(cursorList); // modification done to the iterator are visible in the list
