Assignment Part $1$ Details $$ Class Design

Think of a product that you can buy from a supermarket, like maybe a can of soup or an apple.

Start by listing all the properties of that object that you can think of $$ try to come up with at least ten general

properties of a Product and write these down in your Assignment$\_$Part$\_1\_$ Microsoft

Word document.

Next, use the process of abstraction to cut the number of properties back to only four $$key$$ properties $$ write

these down in the next section of your Word document.

Now, fill in the class diagram for your Product class in the Word document. Your product class does not have

CT$701$ Programming Fundamentals

Page $2$ of $4$

to have any methods $($i$.$e$.$ functions$)$ associated with it to perform any actions other than a constructor which

takes and set the four key properties that you$$ve identified.

Next we$$ll move on to CheckoutRegister class $$ think about what information the checkout has to keep track

of to allow you to successfully check out of the supermarket. There will only really be three key properties that

the CheckoutRegister cares about, and the CheckoutRegister class should have the following four methods

available:

$1)$ A default constructor that takes no arguments and initialises a new object and its properties,

$2)$ accept$\_$payment$($some$\_$amount$),$

$3)$ scan$\_$item$($some$\_$product$),$ and

$4)$ print$\_$receipt$().$

Fill in the class diagram for the CheckoutRegister class in the Word template, and that$$sthe first part completed!
