public class ArrayListDemo {
   public static void main(String[] args) {
      ArrayList<Integer> arrlist = new ArrayList<Integer>(5);
      arrlist.add(15);
      arrlist.add(22);
      arrlist.add(30);
      arrlist.add(40);
      for (Integer number : arrlist) {
         System.out.println("Number = " + number);
      }
      int retval=arrlist.get(3);
