Class ListFlights

java.lang.Object

bcu.cmp5332.bookingsystem.commands.ListFlights

All Implemented Interfaces:

Command

public class ListFlights
extends Object
implements Command

The ListFlights class represents a command to list all flights in the 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 a list of all flights from the FlightBookingSystem instance. It then iterates through the list and prints the short details (using getDetailsShort()) of each flight to the console, excluding any flights marked as deleted.

After listing all flights, it prints the total number of flights retrieved.

Example usage:

 // Create a new ListFlights command instance
 Command listFlightsCommand = new ListFlights();
 
 // Execute the command within a FlightBookingSystem instance
 listFlightsCommand.execute(flightBookingSystem);
