Question

Using the UML from above:

Using the Class diagram, modify the Airplane class to:

Using the Class diagram, create the PassengerAirplane class using the following specifications:

Using the Class diagram, create the JetFighter class using the following specifications:

Extend the Airplane information form to include the following controls:

Using the UML from above: Using the Class diagram, modify the Airplane class to: Create the ToString() method that overrides the System.Object ToString method that creates and returns a well-formatted string that contains the airplane name and position information. Modify the Accelerate and Decelerate methods so that they can be overridden by derived classes. Using the Class diagram, create the PassengerAirplane class using the following specifications: Board plane is a simple method that provides a message to the user that the plane has been boarded. Override the Airplane Accelerate method by invoking the base class accelerate method, and allow the plane to go 500 knots. Override the Airplane Decelerate method to allow the plane to decelerate in increments of 10. Override the ToString method by invoking the Airplane ToString method, and then adding the airline name, flight number, and number of passengers. Using the Class diagram, create the JetFighter class using the following specifications: Override the Airplane Accelerate method and allow the plane to go 2,000 knots, and accelerate in increments of 100. Override the Airplane Decelerate method to allow the plane to decelerate in increments of 100. Override the Airplane TurnLeft and TurnRight methods so that they turn in increments of 20 Override the ToString method by invoking the Airplane ToString method, and then adding the airline fighter type. Extend the Airplane information form to include the following controls: Add a list box, or combo box control, that allows the user to select whether the airplane is a generic airplane, a passenger plane, or a fighter plane. When the user selects the type of plane, create a new object of the identified type. Add a command button, that when selected, provides the information about the specific type of airplane object. [Hint: Program each event handler to handle a generic airplane object, then use the polymorphic methods]. When the user selects the existing operations, the appropriate object-type methods will be invoked.
