Okay, so I attempted to use
timeClock.add(employeeDAO.getEmployee(employeeID)); after using
employeeDAO.readEmployees(), but had to initialize an employeeID in the main method of the TimeClockApp to make it even appear without an error message. However, instead of getting an employeeID recorded in my timeclock.txt file, I am getting "null," even when the employeeID exists in the employee.txt file.
