LAB 5

CMPS 12A
Winter 2015

Due: Mar 6, 2015, Friday, 6:00pm

Objective: Learn more about classes and inheritance.

Assignment:

Implement a simplified airline ticket booking system. Do this by providing two classes: Route class and a Flight class.
The Route class contains information about flights on a specified route between two points. Each route instance should know about its:
```
 source airport 
 destination airport 
 
```
Note that multiple airlines may fly the same route on the same day.
The Flight class extends the Route class. It has all the information about the Route class. In addition, it also maintains the flight details and booking information. Each airline flying a given route has a maximum capacity in terms of how many seats. By default this is set to 100 for all airlines. As seats are booked, each Flight object need to update the number of remaining seats. This class has the following fields:
```
   airlines 
   flightId 
   date
   seats
```
The Flight class cannot have its own source and destination airport fields. These fields must be inherited from the parent class.
To book a ticket, the customer first enters their starting city (source) and their destination. The system then checks if a route exist between that pair of cities. If there is no direct route found, then it displays:
```
No Routes between source and destination. 
```
source and destination are replaced by the source and destination cities respectively. See example below. You do not need to check for connecting routes.
If a route exists between the city pair, then it asks for the departure date. If there are no flights for that route on the travel date, it should print:
```
No Flights between source and destination on travel date. 
```
source and destination are replaced by the source and destination cities respectively. travel date is replaced by the travel date. See example below.
If there are one or more flights flying that day, then it asks for desired flight as identified by its flight ID and number of tickets to book. If there are sufficient seats available, it goes ahead and books the tickets and reduces the number of available seats. If there are insufficient seats available, it should print:
```
Insufficient tickets available. Flight not booked.
```
You will have to maintain two different types of ArrayLists. One for Route class and one for Flight class. You cannot redefine the Route class variables in Flight class. Your program should use inheritance to get the values from base class objects. Your main method should reside in the AirBooking class. This is where the user can access the system to book tickets. Here is a sample input file
```

We would be using stdin to read the data.
Here is the expected output when you run as :

Bonus option.

You may get Bonus points if you check for existence of indirect routes in case of absence of direct routes.
