This is the first part of a larger problem that creates a collection of classes

Question

This is the first part of a larger problem that creates a collection of classes that supports record keeping for a livestock farm. In part 1, you will create three classes to keep health records on livestock.

Part ACreate a class called HealthNote

This class must have the following private data

date (Must be type Dat)

observations (a string)

This class must have the following methods

default constructor

constructor with parameters for the data

copy constructor (This is new to you. See note below.)

Create appropriate accessor and mutator methods to return and modify the private data.

setNote with parameters for the data

toString

Part B

Create a class called VaccinationNote

This class must have the following private data

date (Must be type Dat)

vaccination (a string)

This class must have the following methods

default constructor

constructor with parameters for the data

copy constructor (This is new to you. See note below.)

Create appropriate accessor and mutator methods to return and modify the private data.

setNote with parameters for the data

toString

Part C

Create a class called HealthRecord

This class must have the following private data

birth date (Must be type Dat)

weight (a double)

history (an ArrayList of HealthNote)

vaccinations (an ArrayList of VaccinationNote)

This class must have the following methods

default constructor

constructor with parameters for the data

copy constructor (This is new to you. See note below.)

Create appropriate accessor and mutator methods to return and modify the private data.

setRecord with parameters for the data

toString

addHealthNote (adds a new HealthNote to history)

addVaccinationNote (adds a new VaccinationNote to vaccinations)

Hints

Create a new directory for Project06.

Save a copy of the Dat class in the Project05 directory.

For the HealthRecord class, error check the weight. It can not be less than or equal to zero.

Creating a Copy ConstructorA copy constructor has a single parameter of the same type as the class. It copies the data from the object passed in.

The Fraction class does not have a copy constructor. However, one could be added as follows.

This constructor uses the class accessor methods to copy the data from an object to the newly created object.

When adding objects to ArrayLists in your tester programs, use copy constructors or instantiate anonymous objects as arguments to insure each element of the ArrayList points to a unique object location. See BillTester for an example of instantiating anonymous objects as arguments.

Follow this development process

Create the HealthNote class.

Create a tester program, HealthNoteTester to test all methods and constructors.

Create the VaccinationNote class.

Create a tester program, VaccinationNoteTester to test all methods and constructors.

Create the HealthRecord class.

Create a tester program, HealthRecordTester to test all methods and constructors.

Compile, execute, and test the testing program to be certain all methods work correctly.

As you may not be knowledgeable of animal health issues, here are some sample health notes and vaccinations.

Health Notes

Cow has hardware.

Foot and Mouth Disease (Quarantine herd. Report to Health Department)

Rabies (Quarantine animal. Report to Health Department)

Mastitis (Treat twice a day for one week. Discard milk during treatment and for two weeks after last treatment)

Abscess between toes of right front foot. (Cleaned, treated, and bandaged. If not better in three days, call back.)

Avian Flu (Quarantine flock. Report to Health Department)

Swine Flu (Quarantine herd. Report to Health Department)

Vaccinations

Brucellosis

Rabies

Eastern equine encephalitis

Distemper

Viral respiratory vaccine (IBR, BVD, PI3, BRSV)

Scours

Foot and Mouth Disease
