Use the Iterator returned from ArrayList to loop through an array list


    



import java.util.ArrayList;

import java.util.Iterator;



public class MainClass {

  public static void main(String[] a) {

    ArrayList<String> nums = new ArrayList<String>();

    nums.add("O");

    nums.add("Two");

    nums.add("Three");

    nums.add("Four");



    String s;

    Iterator e = nums.iterator();

    while (e.hasNext()) {

      s = (String) e.next();

      System.out.println(s);

    }

  }

}
