Programming Part:

Design a Ship class that contains 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 no-argument constructor that assigns default values to name (No Name) and year (1776).

An overloaded constructor that accepts name and year

Appropriate accessors and mutators

A toString method 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 to hold the number of passengers (int) with default value of 1000.

A no-argument constructor.

An overloaded constructor that accepts name and number of passengers.

An overloaded constructor that accepts name, year, and number of passengers

Appropriate accessors and mutators

A toString method that overrides the toString method in the base class. The CruiseShip classs toString method should return all Cruise ship information.

Design a CargoShip class that extends the Ship class. The CargoShip class should have the following members:

A field to hold the ship tonnage (int) with default value of 10000.

A no-argument constructor.

An overloaded constructor that accepts name and weight.

An overloaded constructor that accepts name, year, and weight

Appropriate accessors and mutators

A toString method that overrides the toString method in the base class. The CargoShip classs toString method should return all CargoShip information.

Demonstrate the classes in a program that has a Ship array. Complete the class MyShip4.

Implement the Comparable interface to be able to sort the objects by the year.

Use the instanceof to compute the total tonnage and total number of passengers.

and tester be like

import java.util.Collections;

import java.util.ArrayList;

public class MyShip4{

public static void main(String[] args){

//Creates an ArrayList to hold all of the ships

ArrayList ships = new ArrayList<>();

//Populate ArrayList with a number of ship types

ships.add(new Ship("Basic", 1955));

ships.add(new CargoShip());

ships.add(new CruiseShip());

ships.add(new CargoShip("Panama", 250));

ships.add(new CargoShip("Valdosta", 2001, 500));

ships.add(new CargoShip("Atlanta", 1996, 3700));

ships.add(new CruiseShip("Paradise", 3000));

ships.add(new Ship());

ships.add(new CargoShip("Rio", 250));

ships.add(new CruiseShip("Dream", 2000));

ships.add(new CruiseShip("Future", 4500));

ships.add(new CargoShip("Cuba", 432));

ships.add(new Ship("George Washington", 1732));

//1. Traverse the arrayList and display all ship informtion.

//2. Sort all ships by year built on assending order

//3. Traverse the arrayList and display all ship informtion.

//4. Compute the total number of passengers in all cruise ships

//5. Compute the total tonnage of al Cargo ships

//6. Display both total number of passengers and total tonnage

// You should get the following totals:

// Total Tonnage for Cargo Ships 15132

// Total Number of Passengers 10500

}
