(JAVA PROGRAMMING)

I provided the skeleton below. there is lots of code that needs changing. And comments are needed. Please use scanner Keyboard instead of Scanner Sc. I will provide the classes below. There is a (DailyAppointment, MonthlyAppointment, OneTimeAppointment, Appointment, AppointmentsApp)

Read the attached instructions on the Appointment hierarchy and tester class. Then, decide what is the best design for the hierarchy, deliberately selecting the best place to define your instance variables, corresponding getters & setters, and the polymorphic method public boolean occursOn(int year, int month, int day).

This assignment is menu driven and has 2 parts. The first part is when the user is asked to create different types of appointments . The second part is when the user is asked to provide a date so that all of his/her appointments that occur on that date will be listed.

Allow the creation of appointments only once, at the beginning of the program. Ensure the appointments are created before allowing users to check the calendar for appointments created on a specific date.

INSTRUCTIONS

In the driver class:

Code 2 methods:

1. Make Appointments - Fills an array of Appointment objects, with a mixture of appointments and dates and times.

2. Check Appointments - Asks the user to enter a specific date, and print out all the appointments that occur on that date.

Make sure you implement the polymorphic method occursOn() that can be called by any of the objects in the Appointment array.

A sample of the output of the program is as follows:

Please make a selection: 1. One Time Appointment 2. Daily Appointment 3. Monthly Appointment

------------------------------------------------

3 What is the description of your appointment? Piano Lessons

What is your persons name? Ms. Katie

What day of the month is your appointment? (1 - 31) 15

What is the hour of your appointment? (00 -23) 17

What is the minutes of your appointment? (00 -59) 30

Appointment added with Ms. Katie Monthly on day 15 at 17:30

*************Thank you for making all of your appointments.***************** Loop with the following: What is the date you wish to look up in your Appointments' Calendar? Enter the month: 03 Enter the day: 15 Enter the year: 2017 On 3 / 15 / 2017 you have the following appointments: Dentist appointment with Dr. Smith at 13:30 Piano Lessons with Ms. Katie at 17:30 Athletic Training with Ms. Jones at 10:00 Do you wish to look up another date?

(If they answer NO, exit the program with message) Thank you for using your appointment calendar. (If they answer YES, continue to ask for another date to look up). What is the date you wish to look up in your Appointments' Calendar? Etc.

HINT: Try to use the hierarchy of .toString(), so that each level returns a specific string of values available at that level only.

Extra Credit:

Validate that the hour of time and date of a proposed appointment do not conflict with an appointment that is already in the array of appointments. If there is a conflict, as user to select another date or time, and validate again.

SKELETON Driver class (AppointmentsApp) -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

} //In the makeAppointments method, do the following: /** * * * How many appointments do you wish to make? 3 * * Use the number entered by user to instantiate the array of appointments to that size. * * Create a menu for-loop as follows: Please make a selection: 1. One Time Appointment 2. Daily Appointment 3. Monthly Appointment * * For Each option, call a specific method that will request the appropriate data from the user, * and then instantiate the appropriate class/subclass in the Appointment hierarchy * For each appointment made, you will add it to the global array of appointments at the currentSize, * and increment a currentSize global variable that keeps track of the next empty slot in the array. * * * * * //In the checkAppointments method, do the following: * Inside a do-while loop, ask the user the following questions: * What is the date you wish to look up in your Appointments' Calendar? Enter the month: 03 Enter the day: 15 Enter the year: 2017 * (Display the result in the following format:) * * On 3 / 15 / 2017 you have the following appointments: Dentist appointment with Dr. Smith at 13:30 Piano Lessons with Ms. Katie at 17:30 Athletic Training with Ms. Jones at 10:00

Do you wish to look up another date? (If they answer NO, exit the program with message) Thank you for using your appointment calendar.

(If they answer YES, continue to loop.
