                int a = 1, b = 0;
                Paramater obj = new Paramater(a, b);
                Console.Read();
            }
            catch(Exception ex)
            {
                Console.Write(ex.Message);
                Console.Read();
            }
        }
    }

    class Paramater
    {
        int result;
        public Paramater(int a, int b)
        {
            if (b == 0)
                throw new DivideByZeroException("Class:Parameter, from constructor while b==0");
