Answer to Question #317866 in Java | JSP | JSF for rose

Question

Each customer will type in a code representing the structure of his or her 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 five required items. The order code positions, from left to right, represent the following elements:

Five required items:

1. 'A' represents a burrito ($3.00), and 'B' represents a burrito bowl ($4.00).

2. 1 represents black beans (no additional charge), and 2 represents pinto beans (no

additional charge).

3. 1 represents white rice (no additional charge), and 2 represents brown rice ($0.50 extra).

4. 1 represents chicken ($2.00 additional), 2 represents carnitas ($2.50 additional), and 3 represents steak ($3.50 additional).

5. 1 represents mild salsa (no additional charge), 2 represents medium salsa (no additional charge), and 3 represents hot salsa (no additional charge).
