HospitalEmployeeDatabase

The purpose of this project is to implement a system to store data for employees at UAB Hospital. You have to implement a for the user to interact with your system, via things like inputs that lead to different functions that display other things for the user, like the employeeList() function. Another aspect of the project was to implement a way to change the current stored data. I added ways to add and delete employees based on user input. Additionally, I had to implement a function to update the actual uabEmployee.txt file that stores the original employee data with the changes that were made by the user.

I created a ArrayList for every position. I created a class for every position as well, as well as a “SystemTester” class.. I implemented a toString overwrite in HospitalEmployee class, and then overwrote it in every every class, with a “super” call to each parent class’s “toString”. This allows me to implement the toString() function for child classes more easily, because it will automatically display the shared data that the parent class has for toString(). This will make implementing child toString functions less effort and less writing.

I constantly ask for user input in the form of numbers, and this guides the user into which methods they need to be directed towards. The data from uabEmployees.txt is automatically processed line by line, made into an Array split by “ “, and then based on what letter is located at index 0 of each line, an object is created in the correct position. Additionally, based on the letter located at index 0, it asks for different inputs to match the amount of parameters each position object requires. Getters and setters are made for every variable for every position as well.

This comes up when you first run the code. SystemTester’s method Menu() is being displayed:

Here I enter “1” to see the employee list:

It automatically brought me back to the menu, so now I’m going to hit “2” to add an employee.

It will prompt to add all of the necessary information and then it will add the employee:

Lets see it in the list by hitting 1:

Now lets update the txt file. It is not currently exactly like the original since i have been messing with it:

We don’t see the new person we added yet since we haven’t updated, but i’ll hit 3 (update database) now.:

As you can see, in line 7 the new doctor has been added to the txt file. Now I am going to delete him, i’m going to hit 4:

So because I typed Mitchell’s blazerID, it removed him from the system, now to save the changes we can hit update database, 3:

As you can see, the database was updated and Mitchell was removed
