import java.util.LinkedList;
import java.util.List;
import java.util.ListIterator;
public class MainClass {
public static void main(String[] a) {
List list = new LinkedList();
list.add("A");
list.add("B");
list.add("C");
list.add("D");
ListIterator iter = list.listIterator(list.size());
while (iter.hasPrevious()) {
System.out.println(iter.previous());
}
}

While Iterator only supports remove(), ListIterator adds set() and add() methods. |
Using the nextIndex() and previousIndex() methods allows you to find out the index of the
elements around the current cursor position: |
|
public int nextIndex()
public int previousIndex()
