Write a program in Java.

Ship, CruiseShip, CargoShip Classes, and Displayable Interface

Ship class implements Displayable interface.

$```$

public interface Displayable

$\{$

void display$()$;$/$

$\}$

$```$

Design an abstract 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 $($a string$).$

$-$ A constructor and appropriate accessor and mutators.

$-$ A toString method that displays the ships name and the year it was built.

$-$ Override the display$()$ method from Displayable Interface that displays the ships 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, a copy 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 return only the ship's name and the maximum number of passengers.

$-$ Override the display$()$ method from Displayable Interface that displays the cruise ships' information. 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, a copy constructor, and appropriate accessors and mutators.

$-$ 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.

$-$ Override the display$()$ method from Displayable Interface that displays the cargo ships' information.

In a driver program $($shipDemo$.$java$)$

$-$ Demonstrate the classes in a Ship array. Assign various CruiseShip and CargoShip objects to the array elements. The program should then step through the array, calling each object's display$()$ method. $($polymorphism$)$

$-$ Create an ArrayList of Ship objects and add various CruiseShip and CargoShip objects to the array list. The program should then step through the array list, calling each object's toString$()$ method. $($polymorphism$)$

$-$ Test your copy constructors in both CruiseShip and CargoShip in shipDemo.java Resource:

$-$ UML

$-$ Sample Program $($OOP$\_$example$\_2)$
