Assignment 5:
Graphic User Interfaces

The objective of this assignment is to add a partial graphical user interface (GUI) front end to Assignment
4. It is will only be a partial GUI so that this assignment is not too long.
*** Upload .java files, .class files and .txt/.pdf files for documentation within one .zip file ***
Also upload an executable JAR file for your system. Check that your JAR file successfully executes before submitting it, as it is easy to have problems with the manifest file. Include the source files (as well
as executable files) in your JAR file. The addition of the source files is not the default, so you need to select it.
We will run you JAR file to verify that they run as you state. You should also include a ZIP file that
(i) your .java files
(ii) your external documentation
(iii) a listing of the new classes (just the new startup class, and the GUI classes)
(iv) screen shots showing all of the GUI components
The markers will annotate the .java files to provide written feedback on your work.
Graphical User Interface specifications
The entity and container packages should be unchanged. Although, the method getDoctors() was added
to the class Patient so that the doctors of a Patient could be accessed in order to display them in a GUI
window. You should not need to make any changes for your part. The classes in the commands package
should not be changed, although if needed, new commands can be added. The HospitalSystem class and
the interfaces package will not be used. A new class has been added to the startup package to start up
the event-driven application. The new classes that you write are to be placed in the package gui, along
with the GUI classes supplied to you.
When the project first starts, a window should appear for the user to enter the data to create a ward. It
has fields (with prompts) for the entry of the ward name, the first bed label, and the last bed label. In
addition, there is a submit button to submit the information to the system. After the submission, another
window will appear. In the version of the system given to you to start with, the window to appear is the
one for the operations dealing with patients (see the Patient operations window section below for more
detail). This window has four options. The first one is to add a new patient. The second option has a text
field for the entry of a health number. When one is entered and the Enter key is pressed, a new window
(a patient’s window) is opened with information on the patient, and operations on the patient. The third
option is to list all the patients currently in the system. The fourth option is to close this window. This
part of the GUI system is given to you to use.
You need to modify the system so that after submission of the ward information, a different window opens
(the main menu window). It should give the user four buttons to press, as explained below:
The first button of the main menu window will be one to initiate operations on patients of the system.
If it is pressed, a patient operations window appears. This is the same window as presently opens with after
the submission of ward information.
The second button of the main menu window will be one to initiate operations on the doctors of the
system. If it is pressed, a new window (the doctor operations window) appears with four options. The
first option is to add a new doctor. This option should create a new window (doctor add window) where
the data for a new doctor is entered, and a button is pressed to submit the data to the system to add the
new doctor. The second option of the doctor operations window has a text field for the entry of a doctor’s
name. When a name is entered and the Enter key is pressed, a new window (a doctor’s window) is opened
with name and specialty (if any) of the doctor. The doctor’s window should have three options, and an
exit button. The first option is to add a patient to the patients of this doctor. The second is to access a
specific patient of the doctor. This option should open the same patient’s window as accessing a specific
patient from the patient operations window, as mentioned in the third paragraph back. The third option of
the doctor’s window is to remove a patient from the patients of this doctor. The exit button of the doctor’s
window should cause this window to close. Note that the doctor’s window does not display all the patients
of the doctor, as it is anticipated that normally a doctor would have too many to list the all. This is in
contrast to a patient’s window where all the doctors of a patient are listed. The third option of the doctor
operations window lists all the doctors in the system. For simplicity, they can be listed in a JOptionsPane
with default formatting obtained from the dictionary. The last option in the doctor operations window is a
button to close the window. Note to be careful to distinguish between the doctor operations window and a
doctor’s window, as they are two different windows
The third button of the main menu window is to display the information on the ward. It will list each
of the beds. If the bed is empty, there will be a field to enter the health number of a patient to be entered
into the bed. If the bed is occupied, there will be a button to cause the patient to be removed from the
bed. The bottom of this window will have a button to close the window. The ward windowing part of the
GUI system is also given to you. In the version of the system given to you, it can be accessed by pressing
the assign button in a patient’s window.
The fourth button of the main menu window is to terminate the project. The project should also be
able to be terminated by the X in the right hand corner of the main menu window. However, selecting the
X in another window should just close the window (the default action for that (built in) button).
Additional Information
For the main menu window, the four options can be arranged in any pleasing fashion. Don’t spend too much
time making it fancy, but it should be decent. The same applies to the other windows that you develop.
As given to you, there are two main methods that can be used to start the system. The first main method
is in the class for the frame of the patient operations window, the PatientOpsFrame class. The second main
method is in the GuiHospitalSystem class, and it first creates the window to enter the Ward information,
and then again opens the patient operations window. As stated above, you are to change this so that the
main menu window opens after the submission from the ward creation.
Patient operations window : This window has options to add a new patient to the system, access
a specific patient, list all patients, and close the window. If a specific patient is accessed, the window
that appears has the patient’s information. This window is called a patient’s window, as distinct from the
patient operations window just discussed. A patient’s window allows certain operations on the patient. In
particular, if the patient is not presently in a bed, an assign button is in the window that opens the ward
window. In the ward window, the user can assign the patient a bed. Returning to the patient’s window,
if the patient is already in a bed, then a remove button exists to remove the patient from the bed. The
patient’s windows lists all doctors of the patient (each of which can be removed), and has a textfield to add
a doctor to the patient’s list. However, in the version of the classes as given to you, there will be no way
to add doctors to the system, so you cannot add a doctor to the list of doctors of the patient. Of course,
you will be correcting this problem. It is suggested that you first get a basic version of the window working
for the main menu, and have it appear after the ward creation window. In the main menu window, first get
the button working for the patient operations window. Next, the button for the ward window can be done,
and the button to exit the system. After these are working, then start working on the doctor operations
window and the button of the main menu to show it. You can start with only the close button in the doctor
operations window, and then add the others. Note that the doctor operations window will be very similar
to the patient operations window, and the classes for the latter are given to you. Then, you need to build
the window to add a doctor, and the window that appears when a specific doctor is accessed. It is suggested
that initially you don’t worry about error situations.
Additional Guidelines
You are expected to submit the jar file for your system to Moodle. Be sure to specify to include the source
code in the jar file (the default is not to include it). The JAR file is to be executable. We will run your
project, so ensure that the JAR file properly executes – you should check it before submitting it. In addition,
you are to hand in a zip file that includes (i) all of your .java files, and (ii) the external documentation for
the assignment.
External Documentation
For external documentation, include the following:
(i) A description of how to execute your project.
(ii) The status of your assignment.
(iii) Diagram 1: The first diagram should show how you laid out the main menu window. It should show
how you used GUI components in order to place the widgets in the window in appropriate places. It
is a diagram showing what the components do, not the code to lay out the window. It will be similar
to the one drawn in class.
(iv) Diagram 2: The second diagram should be how you laid out the window for adding a new doctor.
Marking (Total 40 marks)
(5) External documentation
(4) the JAR file successfully runs stand alone

(3) Readable code
This is an individual assignment. You are encouraged to discuss the general concepts of classes, types, containers, etc. with you classmates, but the specific details of the Flight Reservation System in this assignment
should be done completely individually.
