(Java) Draw a class diagram for each of the classes

Design a Ship class that 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 and appropriate accessors and mutators. -A toString method that displays the ship's name and the year it was built. Design 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 and appropriate accessors and mutators. -A toString method that overrides the toString method in the base class. The CruiseShip class's toString method should display only the ship's name and the maximum number of passengers. Design 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 and appropriate accessors and mutators -A toString method that overrides the toString method in the base class. The CargoShip class's toString method should display only the ship's name and the ship's cargo capacity.
