Labs

We will be adding to the vehicles.Vehicle hierarchy in this lab. If you did not finish the Vehicle, Automobile, Truck, or Boat classes, use the classes in ...solutions.vehicles.

  1. Create a subclass of Vehicle called FlyingVehicle that contains fields for
  2. Air speed
  3. Range (which is how far it can fly before running out of fuel).

Generate a constructor to set all fields, and getters for the fields.

(Solution: FlyingVehicle.java)

  1. Create a subclass of FlyingVehicle called Plane that has fields for
  2. Name
  3. Passenger capacity

Generate one constructor to set all Plane, FlyingVehicle, and Vehicle fields; a getter for each new field; and a toString() method.

(Solution: Plane.java)

  1. Create a class called TravelingTest with a static main method.
  2. Add a field for an array of Vehicle objects to TravelingTest.
  3. In the TravelingTest constructor, initialize the array to hold 8 vehicles.
    • Create one Automobile object, and add it to the array.
    • Create three Plane objects, with passenger capacities of 5, 75, and 144. Add them to the array.
  4. Add a run method. Create an instance of the class in main and call run to start the program.

TravelingTest functionality is below. Note that it is better to have more methods than fewer. 1. Prompt a user for the number of passengers who will be flying. 2. If the number of passengers is 4 or fewer, the user will travel in the Automobile. Print its information to the screen using toString(). 3. If there are 5 or more passengers, choose the appropriate Plane to accommodate all passengers. (Note that you will have to use casting). 4. If the number of passengers is larger than any available plane, print a message to the screen. 5. Test your program using small and large numbers.

(Solution: TravelingTest.java)
