All Implemented Interfaces:
Command
public class UpdateBooking extends Object implements Command
The UpdateBooking class represents a command to update an existing booking's flight number and booking date within a Flight Booking System. It implements the Command interface, allowing it to be executed within the context of a FlightBookingSystem instance.

Upon execution, the command retrieves the booking identified by bookingID from the provided FlightBookingSystem instance using getBookingByID() method. If the booking does not exist, it throws a FlightBookingSystemException.

If the booking exists, it updates the booking's flight number and booking date to the new values specified during object construction.

Example usage: 


 // Create a new UpdateBooking command instance
 Command updateBookingCommand = new UpdateBooking(bookingID, newFlightNumber, newBookDate);
 
 // Execute the command within a FlightBookingSystem instance
 updateBookingCommand.execute(flightBookingSystem);
