        public Employee(string A1, string A2) : this(0, 0, 0, 0)
        {
            Console.WriteLine(A1.ToString() + " hi " + A2.ToString() );
        }

        }

        public Employee(int A1, int A2, int B1, int B2)
        {
            Console.WriteLine(A1.ToString() + A2.ToString() + B1.ToString() + B2.ToString());
