Create a Class named file that contains the following properties: ID (string), Location (String), CreationDate (DateTime). Then derive a class named Document that has an additional property named Owner (String). Create constructor for both classes that use parameters to initialize all properties.
Solution
Module FileStructure
Public Class File
Public ID As String
Public Location As String
Public CreationDate As DateTime
//constructor
Public Sub New(ByVal id As String,ByVal loc As String,ByVal date As DateTime)
ID=id
Location=loc
CreationDate=date
End Sub
End Class
//Derived Class
Public Class Document Inherits File
Public Owner as String
//constructor
Public Sub New(id As String,loc As String,date As DateTime,onw As String)
Owner=onw
//calling super class constructor
MyBase.New(id)
MyBase.New(loc)
MyBase.New(date)
