Comment utiliser ListIterator en Java

// Java code to illustrate the use of ListIterator
import java.io.*;
import java.util.*;
  
class Test {
    public static void main(String[] args)
    {
        ArrayList<String> list = new ArrayList<String>();
  
        list.add("A");
        list.add("B");
        list.add("C");
        list.add("D");
        list.add("E");
  
        // ListIterator to traverse the list
        ListIterator iterator = list.listIterator();
  
        // Traversing the list in forward direction
        System.out.println("Displaying list elements in forward direction : ");
  
        while (iterator.hasNext())
            System.out.print(iterator.next() + " ");
  
        System.out.println();
  
        // Traversing the list in backward direction
        System.out.println("Displaying list elements in backward direction : ");
  
        while (iterator.hasPrevious())
            System.out.print(iterator.previous() + " ");
  
        System.out.println();
