Review Chapter 7 and Chapter 7 examples. Build an application that handles setting up vacation plans. Create a superclass called Vacation Instance 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.
