  arrayList.add("1");
  arrayList.add("2");
  arrayList.add("3");

  System.out.println("ArrayList contains...");

  // display elements of ArrayList

   System.out.println(arrayList.get(index));

  /*

   */

  Object obj = arrayList.remove(1);
  System.out.println(obj + " is removed from ArrayList");
