Returns a list iterator over the elements in this list (in proper sequence).

Usage

From source file:Main.java

public static void main(String[] args) {
    LinkedList<String> lList = new LinkedList<String>();

    lList.add("1");
    lList.add("2");
    lList.add("3");
    lList.add("4");
    lList.add("5");

    ListIterator itr = lList.listIterator();
    System.out.println("forward direction");

    while (itr.hasNext()) {
        System.out.println(itr.next());
    }/*from w  ww  . jav  a  2  s  . c  o m*/
    System.out.println("reverse direction");
    while (itr.hasPrevious()) {
        System.out.println(itr.previous());
    }
}
