Ada has not had the impact which I and many others anticipated and is
now primarily used for defence and aerospace systems. Few
universities now teach Ada as a first language (I think the last Uk
university changed from Ada to Java this year) so few students
actually understand it.

Personally, I think that Ada is a better language than java for
software engineering but the academic and commercial markets do not
agree. I have to be realistic about this and make changes that are
aimed at the majority of users. I would be surprised if you found any
new texts that used Ada.

I am sorry that you feel unable to use the book - in fact, the Ada
examples from the previous edition are still available through the
website and I do not think that the central message of the book which
is about good software engineering practice is language dependent.

Best wishes

Ian
