Question $1(32$ points$)$:

The objective of this question is to become familiar with objects, and modelling with object types

$($classes$).$ You will not write any code for this questions, rather you will analyze several hypothetical

applications to determine which object types and containers are needed, which attributes$/$fields are

needed for each object, and the methods are needed to interact with each object$$s data.

Your Tasks

For each of the following hypotheticals software systems, you are to provide:

$$ The object types$/$classes involved, with the main fields$/$attributes for each class.

$$ The containers needed, with the type of the items stored in the container, and how the items are

accessed from the container, e$.$g$.,$ in order first to last, by index, by field value, etc. You do not

need to include how the items are stored $($array$,$ linked list, stack, etc$).$

$$ Any important methods, including accessors and mutators when needed. Make sure method

names are descriptive

$$ For each field$/$attribute and method, indicate the visibility $($i$.$e$.,$ public, private, or protected$)$

For this question, since you are not writing any code, submitted files describing the classes must be

in plain text $.$txt files. If other file types are used, you will receive a grade of zero for this question.

You should submit one file for each of the three scenarios $($see submission criteria below$).$

An acceptable format could look like this:

$$

Application : Hotel Management system

Class Hotel

$----------$

Attributes :

$-$ name : String

$-$ address : String

$-$ phone number : String

$-$ Container of Guests

accessed by roomNumber

$----------$

Methods :

$+$ getGuest $()$ : Guest

$+$ addGuest $($ g : Guest $)$ : void

$+$ removeGuest $($ roomNum : int$)$ : void

end of class Hotel

$...$ etc $...$

System $1$: Hospital Application

Consider a Hospital with a fixed number of rooms for patients. The application needs to keep track

of patients, their emergency contact person, and rooms. Patients need to be admitted when brought

to the clinic for care and discharged afterwards. Each room can be empty, or there can be a patient

assigned to it$.$ New patients can only be admitted if there is an available room, and can only be
