        /*
         * Inserts all of the elements in the specified Collection into this
         * Vector at the specified position. Shifts the element currently at
         * that position (if any) and any subsequent elements to the right
         * (increases their indices). The new elements will appear in the Vector
         * in the order that they are returned by the specified Collection's
         * iterator.

        boolean isAdded = vector.addAll(2, arrayList);

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

    }
}

Output

vector  : [10, 20, 30]

arrayList  : [400, 500]

isAdded : true
vector  : [10, 20, 400, 500, 30]
