private, protected, static vars

Posted by Koncept on 12/23/06 20:43

Could somebody please inform me what the difference between setting a
variable as private is compared to protected within a class? I can't
see the difference and would appreciate a brief example. I suspect
this has more to do with subclassing but it eludes me... Also, when is
it appropriate to set a variable to *static* ? Examples are welcome.

Thanks in advance.
