Final (Property Keyword)
Specifies whether this property is final (cannot be overridden in subclasses).
To specify that a property is final, use the following syntax:
Property name As classname [ Final ];
Otherwise, omit this keyword or place the word Not immediately before the keyword.
A class member that is marked as final cannot be overridden in subclasses.
If you omit this keyword, the property is not final.
