Specifies whether this method is final (cannot be overridden in subclasses).
To specify that a method is final, use the following syntax:
Method name(formal_spec) As returnclass [ 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 method is not final.
