Using JAVA, Design a Ship class that has the following members: A field for the name of the ship (a string) A field for the year that the ship was built (an int) A constructor and appropriate accessors and mutators, as well as constructors for no built year provided (set to -1) or no name provided (set to ), or neither provided. A toString method that displays the ships name and the year it was built. If the ship has no name or a negative year of build, unknown should be used instead.

Design a CruiseShip class that is derived from 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, as well as a constructor with only passengers. A toString method that overrides the according method in the superclass. The CruiseShip classs toString method should additionally display the maximum number of passengers.

Design a CargoShip class that is derived from 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, as well as a constructor with only tonnage. A toString method that overrides the according method in the superclass. The CargoShip classs toString method should additionally display the ships cargo capacity.

The Harbor class implements the following interfaces:

Note that there is only one harbor with a fixed space. The Harbor will require a toString method that calls each ships respective toString method, i.e., lists all the ships currently anchored and the one that might be at the pier. If a ship tries to enter the harbor, but there are no anchor spots available, a boolean false should be returned. If the pier is busy, no other ships can be using it. Ships need to anchor before and after they use the pier.
