Emulate a simple long-distance bus service reservation system. We are dealing with a handful of routes each with a number of daily running
buses, each with a specified number of seats.
Each customer that buys a ticket will get an assigned seat.
Invalid reservation will result in an exception.
Here is a possible list
counter is closed,
seats are not available,
service is cancelled,
insufficient funds to purchase,
payment gateway is not responding.
Create collections or lists of relevant objects.
Think of possible objects based on these facts:
Bus Company has Routes
Routes have Buses
Buses have Seats with each seat having a status (occupied or free)
Customer should provide the name and payment information.
Create a demo app.
Implement TicketPurchase as a method in a Transactions object. Pass Route and Customer payment information.
You can emulate exceptions by setting flags in the Transactions objects.
