package tihArrayList;

import java.util.ArrayList;
import java.util.Iterator;

public class UpdateList {

      public static void main(String[] args) {

          //create Array List
          ArrayList tihList = new ArrayList();

          //Add elements to ArrayList

          System.out.println("Original list:" +tihList);                           

          Iterator itr = tihList.iterator();


                String token = itr.next();

                itr.remove();     //removing element from arraylist

                System.out.println("list afer modification:" +tihList);
