I thought it was idiomatic to specify which *kind* of
certification a Java programmer holds.

The answers in this thread have been all over the map.
My interpretation of the original question has it that
William's answer is the only legitimate one--but maybe
the original poster intended something different from
what I read, and likes all those alternatives.

Anyway, the one fundamentally different perspective on
this question I haven't seen anyone mention is what
Pexpect <URL: http://pexpect.sf.net > gives.  From a
Java background, this might come as a revelation--or 
be incomprehensible.
