        System.out.println("Before Sorting  : " + arrayList + "\n");

        /*
         * Sorts the specified list into ascending order, according to the
         * natural ordering of its elements.
         * 
         * All elements in the list must implement the Comparable interface.

        Collections.sort(arrayList);

        System.out.println("After Sorting   : " + arrayList);

    }

}
