1. Java
   1. Build an application that handles setting up vacation plans.
   2. Create an abstract superclass called Vacation
      1. Instance Variables
         1. destination - String
         2. budget - double
      2. Constructors - default and parameterized to set all instance variables
      3. Access and mutator methods
      4. budgetBalance method - abstract method that returns the amount the vacation is under or over budget. Under budget is a positive number and over budget is a negative number.
   3. Create a concrete class called AllInclusive that is a subclass of Vacation and represents an all inclusive vacation like Sandals or Club Med.
      1. Instance Variables
         1. brand - String, such as Sandals , Club Med etc
         2. rating - int, representing number of stars such as 5 star rating.
         3. price - double, the total cost of the vacation
      2. Constructor - default and parameterized to set all instance variables
      3. Accessor and mutator methods
      4. Overwritten budgetBalance method.
   4. Create a concrete class called ALaCarte that is a subclass of Vacation and represents a vacation that requires payment for each activity separately
      1. Instance Variables
      1. 1. hotelName - String
         2. roomCost - double
         3. airline - String
         4. airfare - double
         5. meals - double - estimated total meal expenses.
      2. Constructor - default and parameterized to set all instance variables
      3. Accessor and mutator methods
      4. Overwritten budgetBalance method.
   5. Create JUnit Tests
      1. Create JUnit Tests to test the budgetBalance methods in both the AllInclusive and ALaCarte classes.
      2. Test each method from polymorphically via an object variable that is of type Vacation.
      3. Review the JUnit API and documentation as since the budgetBalance method returns a double, you will need to use one of the assertEquals methods that handles doubles since doubles values may not be exact due to rounding errors.
   6. Create a VacationTester class
      1. Test all methods.
      2. Create at least 2 object of each Vacation subclass
      3. Place those object in an array of type Vacation.
      4. Loop through the array and polymorphically call the budgetBalance and display the results.
