        System.out.println("Print value of int[]");
        /* Print value of array */
        for (int i : intArray) {
            System.out.println(i);
        }
        
        /**
         * Declare and Initialize Integer Array.
         * Integer can hold `null` values.
         */
        Integer integerArray[] = {10, 20, null};
        
        System.out.println("Print value of Integer[]");
        for (Integer i : integerArray) {
            System.out.println(i);
        }
