What happened to “private protected”?
• A. It first appeared in JDK 1.0 FCS (it had not been in the Betas). Then it was removed in JDK 1.0.1. It was an ugly hack syntax-wise, and it didn’t fit consistently with the other access modifiers. It never worked properly: in the versions of the JDK before it was removed, calls to private protected methods were not dynamically bound, as they should have been. It added very little capability to the language. It’s always a bad idea to reuse existing keywords with a different meaning. Using two of them together only compounds the sin. The official story is that it was a bug. That’s not the full story. Private protected was put in because it was championed by a strong advocate. It was pulled out when he was overruled by popular acclamation.
