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

        /*
         * Returns the minimum element of the given collection, according to the
         * natural ordering of its elements.

        Integer minElement = Collections.min(arrayList);

        System.out.println("minElement : " + minElement);
