[RESOLVED] Properties, Enumeration, & Constructors

[EmilyM1105]

Im doing step by step..My instructions are:


The GroceryItem class should contain the following public properties:

1. ScanNumber - Represents the unique serial code for the item on the shelf. This property should be read-only.

2. BrandName - The name as described on the item’s packaging

3. Description - A short description of the item

4. Price - The amount of money it costs to buy the item. Make sure that only positive values can be assigned to this property.

5. Aisle - This should indicate one of the following aisles: Bakery, CannedGoods, Drinks, Deli, DryGoods, FrozenFoods, and Produce.

This is my Grocery Item code:

Public Class GroceryItem
   Public ReadOnly Property ScanNumber As Integer
Get
  Return ScanNumber
End Get
    End Property

    Public Property BrandName As String
 Get
   Return BrandName
 End Get
 Set (value As String)
   BrandName = value
 End Set
End Property

    Public Property Description As String
Get
Return Description
End Get
Set (value As String)
 Description = value
End Set
End Property

    Public Property Price As Integer
Get
Return Price
End Get
Set (value As Integer)
Price = value
End Set
End Property

    Public Property Aisle As String
Get
Return Aisle As String
End Get
Set (value As String)
Aisle = value
End Set
End Property
End Class

It says you can use enumeration.

The GroceryItem class should contain the following public constructors:

1. A constructor that accepts and sets only the ScanNumber property. Remember: If a property is read-only, then you’ll need to set the variable, not use the property name.

2. A constructor that accepts and sets the ScanNumber, BrandName and Price properties.

Add a new public class named GroceryBasket to the project.

1. Derive from the generic List class.
2. Ensure that only GroceryItem objects are stored as items.

Add the following variable declaration to the Main module: Friend basket As New GroceryBasket

My Main Code:

Module Main
    Friend blnLoggedIn As Boolean
    Dim arrUsernames() As String = {"Admin", "Clerk", "Manager"}
    Dim arrPasswords() As String = {"P@ssword", "pa$$word", "passw0rd"}
    Dim userIndex As Integer
    Friend basket As New GroceryBasket

Test your work.

Note: You can add code to the btnLogin_Click event handler procedure to instantiate the GroceryItem class and add multiple objects to the GroceryBasket variable. Make sure you either remove or comment out this code after testing.
