High St. Hospital

Objective

• Students will employ good software design and testing principles in order to create a class hierarchy using OO principles (Abstraction, Polymorphism, Inheritance and Encapsulation).
• Students will be able to define super, extends,isA and typeof

The Scenario

High St. Hospital is an organizational mess. They have unkempt files of employee information scattered throughout manilla folders, computer data files, and old tin filing cabinets. With the madness of the daily grind, patients are the priority. But the utmost care cannot be given to the patients if the hospital is disorganized. High St. Hospital wants to get it together. They have subcontracted We Can Code IT full-stack apprentices (who work for the relatively inexpensive price of free) to come in and organize. They enable you to set up shop with a few company laptops in an old dissheveled break room. Your mission is to create a set of classes that contain information on the employees at High St. Hospital:

Patients Should Hav

• default BLOOD_LEVEL of 20 (What does this naming convention suggest again???)
• default HEALTH_LEVEL of 10

High St. Hospital has the following classifications at its facility

• Employee represents a base employee. All others Hospital employees are Employees
• Doctor is a Hospital Employee and gets paid 90,000
• Nurse is a Hospital Employee and gets paid 50,000
• Surgeon is a Doctor and gets paid 120,000
• Receptionist is a Hospital Employee and gets paid 45,000
• Janitor is a Hospital Employee and gets paid 40,000

The Data

The following Instance Data will need to be taken care of for each employee

• Employees have a name and ID number
• Doctors have a name, ID number, and a specialty area (Heart, Brain, Foot, etc…).
• Surgeons have a name, ID number, a specialty area, and whether they are operating or not.
• Nurses have a name, ID number, a Collection of Patients.
• Receptionists have a name, ID number, and whether they are on the phone or not.
• Janitors have a name, ID number, and whether they are sweeping or not.
• VampireJanitors have a name, ID number, whether they are sweeping or not.

Special Duties

Not all employees in the hospital have the same capabilities. Only certain staff members can implement certain medical duties such as drawBlood() or careForPatient()

Getting Started

Plan -> Prepare -> Program

1. First, start by mapping out relationships. See what Classes you will need and how they interact with each other. (Pen and paper)
2. Next, prepare a project using NPM. Set up a git repository for your project and a corresponding one on GitHub. If you are pairing, make sure your partner has access to the repo and the ability to push and pull. Make sure you are following best practices. (Make sure to have a master branch, a dev branch, and give feature-branches a shot)
3. Start programming. Remember to start with specifics and work toward generality. Choose one type of employee to create, test drive that class. Once that one is finished, pick another and pull similarities up into a parent class or interface.

As you look at this output to the console, the true/false attached to some of the employees simply represents the state they are in relative to if they are currently involved in their jobs or not.

Stretch Tasks

Give Stretch Tasks a shot ONLY after requirements have been met. Completion of stretch tasks won't give you any extra credit, but, if your attempt breaks a requirement, that will cost you points. I suggest using feature branches to implement Stretch Tasks after requirements are finished.

• Stretch task: Tina is an EmergencyDispatcher. She is a trained medical professional and a first responder. She also has great people skills and can answer calls and manage what ambulance gets sent to a situation. She sometimes joins the crew and respondes to calls on the fly. Add her as an employee and give her the proper functionality. This job pays 45,000.
• Stretch task: Search for an individual employee by name and access their info/what they are doing
• Stretch task: add an employee, fire an employee
