Final answer:
The student is tasked with creating a Java program for a food ordering system using the Scanner for input and else if statements for control flow, without external libraries. The program should include functionality for adding food items, viewing and clearing the cart, checking out with tax and delivery fees, and exiting the program.
Step-by-step explanation:
Implementation of a Food Ordering Program
The task is to create a food ordering program that allows a user to perform various functions such as adding food to the cart, viewing the order, clearing the order, checking out, and exiting the program. The program is expected to handle user inputs for the food item and quantity, calculate subtotals, manage cart content, and finalize the order with a payment process. The checkout process includes a tax calculation and an additional fee for delivery. Throughout the implementation, the Scanner class will be used to accept user input, and else if statements will be utilized for control flow. It is important to note that the use of external libraries is not permitted in the coding of this program.
An example implementation in Java could include a main menu loop with options to add food, view order, clear order, checkout, and exit. A switch statement would handle the navigation based on the user's choice. Additional functions such as calculating tax, adding a delivery fee, and processing the user's card number could also be part of the program.
