All Implemented Interfaces:
Command
public class AddBooking extends Object implements Command
The AddBooking class represents a command to add a booking to the flight booking system. It implements the Command interface and requires execution within a FlightBookingSystem instance.

The booking is associated with a specific customer and outbound flight on a specified booking date. If the outbound flight is at full capacity, the booking cannot be issued, and an exception is thrown. Upon successful booking, the updated system data is stored using FlightBookingSystemData.

Example usage: 


 int customerId = 1;
 int outboundFlightId = 101;
 LocalDate bookingDate = LocalDate.now();
 Command addBookingCommand = new AddBooking(customerId, outboundFlightId, bookingDate);
 addBookingCommand.execute(flightBookingSystem);
