Practice by making a Ship class with the following members: A field for the name of the ship (a string) A field for the year that the ship was built (a string) A constructor that accepts two arguments for the two fields, and appropriate accessors and mutators A toString method that returns a string with the ship's name and the year it was built Practice by making a CruiseShip class that extends the Ship class. The CruiseShip class should have the following members: A field for the maximum number of passengers (an int) A constructor that accepts three arguments for the three fields and appropriate accessors and mutators A toString method that overrides the toString method in the base class. The CruiseShip class's toString method should return a string with only the ship's name and the maximum number of passengers. Practice creating a CargoShip class that extends the Ship class. The CargoShip class should have the following members: A field for the cargo capacity in tonnage (an int) A constructor that accepts three arguments for the three fields and appropriate accessors and mutators A toString method that overrides the toString method in the base class. The CargoShip class's toString method should return a string with only the ship's name and the ship's cargo capacity. Practice all the above classes in a test program that creates related objects and prints their details (by implicitly/explicitly invoking the related toString methods).
