        private double weight;

        }

            this.weight = weight;
            this.tiji = tiji;
           
        }
        public double midu()
        { 
        
            return (weight/tiji);
        }
        public void panduan()
        {
            if (midu() == 1)
            {
                Console.WriteLine("物体会悬浮");
            }
            if (midu() < 1)
            {
                Console.WriteLine("物体会上浮");

            }
            else
            {
                Console.WriteLine("物体会下沉");
            }
        
        }

    
    }
    class Program
    {
        static void Main(string[] args)
        {
            PhysicalObject s = new PhysicalObject(20, 15);
            s.midu();
            s.panduan();
            Console.ReadKey();
        }

    }
}

运行结果：

心得体会：呵呵
