Specifies whether this method is private (can be invoked only by methods of this class or its subclasses).
To specify that the method is private, use the following syntax:
Method name(formal_spec) As returnclass [ Private ]
Otherwise, omit this keyword or place the word Not
immediately before the keyword.
Private class members can be used only by other members of the same class (or its subclasses). Note that other languages often use the word protected
to describe this kind of visibility and use the word private
to mean invisibility from subclasses.
This keyword is inherited but you can change its value in subclasses.
If you omit this keyword, this method is not private.
