Question

Write a program that assigns seats on an airplane. Assume the airplane has 20 seats in the first class (5 rows of 4 seats

each, separated by an aisle) and 90 seats in economy class (15 rows of 6 seats each, separated by an aisle). Your

program should take three commands: add passengers, show seating, and quit. When passengers are added, ask for the

class (first or economy), the number of passengers traveling together (1 or 2 in the first class; 1 to 3 in economy), and

the seating preference (aisle or window in the first class; aisle, center, or window in economy). Then try to find a match

and assign the seats. If no match exists, print a message stating as such. Your solution should include a class

Airplane that is not coupled with the Scanner or Printstream classes. Be sure to include any other classes that

you need to complete this program using the design process described in Chapter 12.
