Question

Java Program Please help me with this. It should be pretty basic and easy but I am struggling with it. Thank you

Create a superclass called VacationInstance Variables

destination - String

budget - double

Constructors - default and parameterized to set all instance variables

Access and mutator methods

budgetBalance method - returns the amount the vacation is under or over budget. Under budget is a positive number and over budget is a negative number. This method will be overwritten in the subclass so have it return Java's integer minimum value.

Create a concrete class called AllInclusive that represents an all inclusive vacation like Sandals or Club Med.Instance Variables

brand - String, such as Sandels , Club Med etc

rating - int, representing number of stars such as 5 star rating.

price - double, the total cost of the vacation

Constructor - default and parameterized to set all instance variables

Accessor and mutator methods

Overwritten budgetBalance method.

Create a concrete class called ALaCarte - a pay for each activity separately

Instance Variables

hotelName - String

roomCost - double

airline - String

airfare - double

meals - double - estimated total meal expenses.

Constructor - default and parameterized to set all instance variables

Accessor and mutator methods

Overwritten budgetBalance method.

Create a VacationTester class

Test all methods of both classes, however test methods in the superclass Vacation from either subclass object (AllInclusive or ALaCarte)

Polymorphically call the budgetBalance method by creating at least 2 object of each Vacation subclass, and place those object in a collection of the Vacation object.

Vacation class

package vacation;

public abstract class Vacation {

public Vacation(String destination, double budget) {

this.destination = destination;

this.budget = budget;

}

public Vacation() {

}

private String destination;

private double budget;

public String getDestination() {

return destination;

}

public void setDestination(String destination) {

this.destination = destination;

}

public double getBudget() {

return budget;

}

public void setBudget(double budget) {

this.budget = budget;

}

abstract public int budgetBalance();

}

AllInclusive class

package vacation;

public class AllInclusive extends Vacation {

public AllInclusive(String destination, double budget, String brand, int rating, double price) {

super(destination, budget);

this.brand = brand;

this.rating = rating;

this.price = price;

}

public AllInclusive() {

}

@Override

public int budgetBalance() {

return (int) (getBudget() - price);

}

public String getBrand() {

return brand;

}

public void setBrand(String brand) {

this.brand = brand;

}

public int getRating() {

return rating;

}

public void setRating(int rating) {

this.rating = rating;

}

public double getPrice() {

return price;

}

public void setPrice(double price) {

}

private String brand;

private int rating;

private double price;

}

ALaCarte class

package vacation;

public class ALaCarte extends Vacation {

private String hotelName;

private double roomCost;

private String airline;

private double airfare;

private double meals;

@Override

public int budgetBalance() {

double totalCost = roomCost + airfare + meals;

return (int) (getBudget() - totalCost);

}

public ALaCarte(String destination, double budget, String hotelName, double roomCost, String airline,

double airfare, double meals) {

super(destination, budget);

this.hotelName = hotelName;

this.roomCost = roomCost;

this.airline = airline;

this.airfare = airfare;

this.meals = meals;

}

public ALaCarte() {

}

public String getHotelName() {

return hotelName;

}

public void setHotelName(String hotelName) {

this.hotelName = hotelName;

}

public double getRoomCost() {

return roomCost;

}

public void setRoomCost(double roomCost) {

this.roomCost = roomCost;

}

public String getAirline() {

return airline;

}

public void setAirline(String airline) {

this.airline = airline;

}

public double getAirfare() {

return airfare;

}

public void setAirfare(double airfare) {

this.airfare = airfare;

}

public double getMeals() {

return meals;

}

public void setMeals(double meals) {

this.meals = meals;

}

}

VacationTester class

package vacation;

import java.util.ArrayList;

public class VacationTester {

public static void main(String args[]) {

AllInclusive allInclusive = new AllInclusive("Miami", 3500, "Sandals", 4, 4500);

ALaCarte aLaCarte = new ALaCarte("Miami", 3500, "Drive Sern", 2000, "Emirates", 800, 400);

System.out.println(" All Inclusive data : ");

System.out.println("Destination : " + allInclusive.getDestination());

System.out.println("Bugdet : " + allInclusive.getBudget());

System.out.println("Brand : " + allInclusive.getBrand());

System.out.println("Rating : " + allInclusive.getRating());

System.out.println("Price : " + allInclusive.getPrice());

System.out.println("Budget Balance : " + allInclusive.budgetBalance());

System.out.println("\n\n Ala Carte data : ");

System.out.println("Destination : " + aLaCarte.getDestination());

System.out.println("Bugdet : " + aLaCarte.getBudget());

System.out.println("Hotel Name : " + aLaCarte.getHotelName());

System.out.println("Room Cost : " + aLaCarte.getRoomCost());

System.out.println("Airline : " + aLaCarte.getAirline());

System.out.println("Airfare : " + aLaCarte.getAirfare());

System.out.println("Meals : " + aLaCarte.getMeals());

System.out.println("Budget Balance : " + aLaCarte.budgetBalance());

// Added both object in collection of super class

ArrayList<Vacation> vacationsList = new ArrayList<>();

vacationsList.add(allInclusive);

vacationsList.add(aLaCarte);

}

}

OUTPUT ::
