// Import the ArrayList class and the Iterator class
import java.util.ArrayList;
import java.util.Iterator;

public class Main {
  public static void main(String[] args) {

    // Make a collection
    ArrayList<String> cars = new ArrayList<String>();
    cars.add("Volvo");
    cars.add("BMW");
    cars.add("Ford");
    cars.add("Mazda");

    // Get the iterator
    Iterator<String> it = cars.iterator();

    // Print the elements in the list
    while(it.hasNext()){
    System.out.println(it.next());
    }
  }

// Create an iterator
Iterator iterator = notificationList.createIterator();
// It wouldn’t matter if list is Array or ArrayList or
// anything else.
while (iterator.hasNext())
{
    Notification notification = iterator.next());
}
