double Topping_Cost=1.50; //constant per topping double Small_Cost=9.50; // cost for small sized pizza double Medium_Cost= 12.25;// cost for medium sized pizza double Large_Cost=14.50; //cost for large size pizza. double Sum_Toppings;// the total cost of toppings double Total_Cost=0;// total cost of pizza double base_cost=0;// base cost of the sizes double Amount=0; int index =0; double Toppings_size=0; if (base_cost==0) { if(Size.equalsIgnoreCase("Small")) { base_cost= Small_Cost; } else if(Size.equalsIgnoreCase("Medium")) { base_cost= Medium_Cost; } else { base_cost=Large_Cost; } while(index<7 && Toppings[index]!= null) { Amount++; index++;

} Total_Cost = base_cost +(Toppings_size* Topping_Cost); }

return Total_Cost;

}// pizza

// number of toppings of the pizza

who = new Pizza(Crust,Size,Toppings); pizzas.add(who);

} } // method readData

How it is displaying.
