Question
Write an abstract super class encapsulating a vacation: A vacation has two attributes: a budget and a destination. It has an abstract method returning how much the vacation is over or under budget. This class has two non-abstract subclasses: one encapsulating an all-inclusive vacation, and the other encapsulating a vacation bought piece-meal. An all-inclusive vacation has three additional attributes: a brand (for instance ClubMed); a rating, expressed as a number of stars; and a price. A piecemeal vacation has two additional attributes: a set of items (hotel, meal, airfare), and a set of corresponding costs. You also need to include a client class to test these two classes using either an ArrayList or an array of objects to populate the array, print the state of each element and the total costs for all vacations. Also include and test an abstract calculate cost method that returns the total cost of each vacation.
Explanation / Answer
Program Code:
//abstract class Vacation
public abstract class Vacation
{
//protected instance variables
protected double budget;
protected String destination;
//abstract method
abstract double overOrUnderBudget();
abstract double TotalCost()
}
//Encapsulating the AllInclusiveVacation class
class AllInclusiveVacation extends Vacation
{
//declare the variables
protected String brand;
protected int rating;
protected double price;
AllInclusiveVacation(String dest, double bud, String b, int r, double p)
{
destination=dest;
budget=bud;
brand=b;
rating=r;
price=p;
}
//TotalCost method that returns total vacation value
public double TotalCost()
{
return price;
}
//define the overOrUnderBudget method that returns
//a double value
public double overOrUnderBudget()
{
return budget-price;
}
//toString() method that returns a string value
public String toString()
{
String s="";
s+="Destination: "+destination+" Budget: "+budget;
s+=" Brand: "+brand+" Rating: "+rating+" Price: "+price;
s+=" Budget Left: "+overOrUnderBudget();
return s;
}
}
import java.util.ArrayList;
class PiecemealVacation extends Vacation
{
protected double totalPrice;
public String[] item={"Hotel", "Meals", "Airfair"};
private ArrayList<Double> costs;
PiecemealVacation(String dest, double bud, ArrayList<Double> cost)
{
destination=dest;
budget=bud;
costs=cost;
}
//TotalCost method
public double TotalCost()
{
totalPrice=0;
for(int i=0;i<item.length;i++)
{
totalPrice+=costs.get(i);
}
return totalPrice;
}
//define the overOrUnderBudget method that returns
//a double value
public double overOrUnderBudget()
{
totalPrice=0;
for(int i=0;i<item.length;i++)
{
totalPrice+=costs.get(i);
}
return budget-totalPrice;
}
//toString() method that returns a string value
public String toString()
{
String s="";
s+="Destination: "+destination+" Budget: "+budget;
for(int i=0;i<item.length;i++)
s+=" Item: "+item[i]+" Cost: "+costs.get(i);
System.out.println(overOrUnderBudget());
s+=" Budget Left: "+overOrUnderBudget();
return s;
}
}
import java.util.*;
// A client class to test these two classes.

System.out.println("3.Quit");
System.out.println("Enter your choice: ");
