But, as Mr. Kennedy notes in a separate contribution to this
thread,

"Actually, this doesn't accomplish as much as you wish, in practice, as
it will eventually be necessary to have a constructor for the real
class, or else a static factory method."

Until I began this conversation, and after doing additional research, I
was unaware of just how bad the situation with Java was.   The more
I examined this issue, with that additional research, it became clear
that Ada's model is even better than I had realized.

All the protestations in favor of Java simply fail to square with the
reality of Java practice.
