Question

Project part 3:

Part Three: Complete the addShip() Method

1. In the Driver.java file, see below for where you will add code to finish the addShip() method.

// Add a New Ship public static void addShip() {

// complete this method

}

2. Next, review the required functionality of the “Add Ship” menu option below.

Menu Option Validation Check(s) Functionality
Add Ship - Ensures ship does not already exist in our system - Ensures all class variables are populated
Adds ship to system

3. Add Ship Method: Write the code for the addShip() method. When your code is complete, test the output. Be sure that the completed method does the following:

a. Adds a new Ship object b. Includes all class variables c. Updates appropriate ArrayList

TIP: You can refer to the Ship.java class constructor to make sure you have included all variables.

Here is the given ship code:

public class Ship {

// Class Variables
private String shipName;
private int roomBalcony;
private int roomOceanView;
private int roomSuite;
private int roomInterior;
private boolean inService;

// Constructor - default
Ship() {
}

// Constructor - full
Ship(String tName, int tBalcony, int tOceanView,
int tSuite, int tInterior, boolean tInService) {
shipName = tName;
roomBalcony = tBalcony;
roomOceanView = tOceanView;
roomSuite = tSuite;
roomInterior = tInterior;
inService = tInService;
}

// Accessors
public String getShipName() {
return shipName;
}

public int getRoomBalcony() {
return roomBalcony;
}

public int getRoomOceanView() {
return roomOceanView;
}

public int getRoomSuite() {
return roomSuite;
}

public int getRoomInterior() {
return roomInterior;
}

public boolean getInService() {
return inService;
}

// Mutators
public void setShipName(String tVar) {
shipName = tVar;
}

public void setRoomBalcony(int tVar) {
roomBalcony = tVar;
}

public void setRoomOceanView(int tVar) {
roomOceanView = tVar;
}

public void setRoomSuite(int tVar) {
roomSuite = tVar;
}

public void setRoomInterior(int tVar) {
roomInterior = tVar;
}

public void setInService(boolean tVar) {
inService = tVar;
}

// print method
public void printShipData() {
int spaceCount;
String spaces = "";
spaceCount = 20 - shipName.length();

for (int i = 1; i <= spaceCount; i++) {
spaces = spaces + " ";
}

System.out.println(shipName + spaces + roomBalcony + "\t" +
roomOceanView + "\t" + roomSuite + "\t" +
roomInterior + "\t\t" + inService);
}

// method added to print ship's name vice memory address
@Override
public String toString() {
return shipName;
}
}

And here is the driver code that needs to be completed:
