[edit | edit source]

This exercise comprises of a base class WaterVehicle. It will also have a class Ship, a class Boat, a class WaterAirplane, and a class Submarine.

WaterVehicle Methods:

updateSpeed(int) will update the speed to a valid speed - higher than minSpeed and lower than maxSpeed

You can choose what to use.

Note: Ship, Boat, and WaterAirplane should extend WaterVehicle.

When you are done, you can create a main class to run your program. For example, the main class could create an instance of WaterAirplane and try using the methods.
