i have this code that is not working but I do not know what it is.

here is the code;

        // Create space for stock objects.
        Share[] stock = new Share[20];

        for(int x = 0; x<stock.length; x++)
        {
            stock[x].price = x;
            System.out.println(stock[x].price);
        }

        class stock(){

            public int price;

            public stock(){
              this.price = 30;
            }

        }

It should output 20 different numbers, but nothing outputs.
