Answer to Question #317868 in Java | JSP | JSF for rose

Question

Each customer will type in a code representing the structure of their order, and your program will display (to standard output) a summary of the order components along with the total cost. An order code is exactly nine characters long, representing four optional toppings. The order code positions, from left to right, represent the following elements:

Four optional Items:

1. 'Y' means the customer wants corn (no additional charge), and 'N' means that the customer does not want corn.

2. 'Y' means that the customer wants guacamole ($0.50 extra), and 'N' means that the

customer does not want guacamole.

3.. 'Y' means that the customer wants sour cream (no additional charge), and 'N' means that the customer does not want sour cream.

4.. 'Y' means that the customer wants cheese ($0.50 extra), and 'N' means that the customer

does not want cheese.
