Question

Project Part 4:

Part Four: Complete the addCruise() Method

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

// Adda New Cruise public static void addCruise() {

// complete this method

}

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

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

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

a. Prompts the user for input b. Requires all class variables when creating a cruise c. Validates the ship name and ensures it is in service d. Ensures ship name is not already assigned a cruise e. Adds the new cruise to the cruiseList ArrayList if validation checks

Given cruise code:

public class Cruise {

// Class Variables
private String cruiseName;
private String cruiseShipName;
private String departurePort;
private String destination;
private String returnPort;

// Constructor - default
Cruise() {
}

// Constructor - full
Cruise(String tCruiseName, String tShipName, String tDeparture, String tDestination, String tReturn) {
cruiseName = tCruiseName;
cruiseShipName = tShipName;
departurePort = tDeparture;
destination = tDestination;
returnPort = tReturn;
}

// Accessors
public String getCruiseName() {
return cruiseName;
}

public String getCruiseShipName() {
return cruiseShipName;
}

public String getDeparturePort() {
return departurePort;
}

public String getDestination() {
return destination;
}

public String getReturnPort() {
return returnPort;
}

// Mutators
public void setCruiseName(String tVar) {
cruiseName = tVar;
}

public void setCruiseShipName(String tVar) {
cruiseShipName = tVar;
}

public void setDeparturePort(String tVar) {
departurePort = tVar;
}

public void setDestination(String tVar) {
destination = tVar;
}

public void setReturnPort(String tVar) {
returnPort = tVar;
}

// print cruise details
public void printCruiseDetails() {

// complete this method

}
