Activity 1:

1. Review Chapter 8 and All Inheritance examples.
2. Build an application that handles setting up vacation plans.
3. 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.
4. Create a concrete class called AllInclusive that is a subclass of Vacation and represents an all inclusive vacation like Sandals or Club Med.

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

   2. Constructor - default and parameterized to set all instance variables
   3. Accessor and mutator methods
   4. Overwritten budgetBalance method.
5. 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

   2. Constructor - default and parameterized to set all instance variables
   3. Accessor and mutator methods
   4. Overwritten budgetBalance method.
6. Create a VacationTester class
   1. Test all methods.
   2. 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.
