Flights has two types also Cargo Flights and PassengerFlights. CargoFlights add load of the flight in tons and the cost per ton. PassengerFlights add the list of passengers. All flights must have functionality to calculate the revenue of the flight based on the following table: CargoFlights Load(Tons)*Cost Per Ton PassengerFlights The summation of the ticket price of all passengers of the flight Pilots and Passengers are persons, Persons have name, nationality and passport number. Each Passenger has the number of travelled KM and the ticket price. Pilots stores the flying hours and a list of spoken languages. Note: Flights and Aircrafts are too general. system using a suitable object oriented language. ii) Explain the term "Polymorphism". Demonstrate with the aid of a code snippet, how polymorphism can be achieved via method redefinition from the inheritance" code that you have produced in task 3 - (i). I) Provide screen shots in addition to source code as evidence of program execution Flights has two types also Cargo Flights and PassengerFlights.
