4. In a restaurant, whenever customers visit, they are provided with items from two categories, one category is fixed for every customer like water bottle, salad and another category is according to the list items that the customer orders like number of biriyani plates, number of dosas etc. ow, write an abstract class fixedCategory having the price of the fixed items as data member and an abstract method complimentaryCost(). frite another derived class orderedCategory which will have price of the food items that the customer has ordered as instance variable and one method ordereditemsCost() which will calculate the cost of rdered items. Also implement the abstract method complimentaryCost() in this derived class to find the cost for complementary items. Assume the customer has ordered each food item only once. Irite a java code to display the attributes from each of the classes creating proper instances and invoking the methods from another main class customerCost. Assume price of water bottle is 20, salad 80, iriyani 450, dosa 150.

Q4. In a restaurant, whenever customers visit, they are provided with items from two categories, one category is fixed for every customer like water bottle, salad and another category is according to the list of items that the customer orders like number of biriyani plates, number of dosas etc. Now, write an abstract class fixedCategory having the price of the fixed items as data member and an abstract method complimentaryCost(). Write another derived class orderedCategory which will have price of the food items that the customer has ordered as instance variable and one method orderedltemsCost() which will calculate the cost of ordered items. Also implement the abstract method complimentaryCost() in this derived class to find the cost for complementary items. Assume the customer has ordered each food item only once. Write a java code to display the attributes from each of the classes creating proper instances and invoking the methods from another main class customerCost.
