All Implemented Interfaces:
Command
public class DeleteFlight extends Object implements Command
The DeleteFlight class represents a command to delete a flight from the flight booking system. It implements the Command interface, allowing it to be executed within the context of a FlightBookingSystem instance.

Upon execution, the flight with the specified flight number is removed from the system. The modified system data is then stored using FlightBookingSystemData.

If the flight with the specified flight number does not exist in the system, a FlightBookingSystemException is thrown.

Example usage: 


 // Create a new DeleteFlight command instance for flight with number "FL123"
 Command deleteFlightCommand = new DeleteFlight("FL123");
 
 // Execute the command within a FlightBookingSystem instance
 deleteFlightCommand.execute(flightBookingSystem);
