So the Ship class is the super class while CargoShip and CruiseShip both extend the Ship class. I've stored the 3 objects into a Ship array. setCargoCapacity and setMaxPassengers are methods that only appear in the subclasses. For some reason I cannot access them. I can't figure out how to make it so that I can also access the subclass methods.
You could initialize your objects before storing them in the array:
Ship ships = new Ship();
ships.setShipName("Boom");
ships.setYearBuilt("1900");
CargoShip cargoShips = new CargoShip();
cargoShips.setShipName("Bang");
cargoShips.setCargoCapaicty(200);
CruiseShip cruiseShips = new CruiseShip();
cruiseShips.setShipName("Bam");
cruiseShips.setMaxPassengers(500);
Ship[] allShips = {ships, cargoShips, cruiseShips};
