It is a shame that the idiots in charge of Java don't have enough brains to look at the
generic/template models of Ada and C++.  I am currently working on a couple of papers with
two of my colleagues on Java's lack of template/generic capabilities. One of my colleagues is
a C++ guy and we have been comparing Ada generics and C++ templates with an eye towards how
we might like to see a generic/template feature implemented in Java.

The issue is much deeper than that.  How many students go through an undergraduate program
with any real software reuse experience (I can see it now, I am about to get flamed).  People
seem to claim as software reuse experience by just throwing any crap they want into a library
and presto they are doing reuse.

Granted, there are some pretty good libraries out there in C++ and Java, but I just did a
survey of CS 2 and CS 7 (Advanced data structures and algorithms) texts using C++.  Would you
believe that I could not find one book that uses C++ templates to encapsulate the basic data
structures?  If one of you know one, let me know.

Now keep in mind that just about all the Java book for these courses are "global replaces" of
the various author's C++ books and you can see that we are facing a generation of programmers
who have been raised on C++ and Java and have no real clue as to how to use a
generic/template for the construction of reusable software!

If the software industry is in trouble now, I have a pretty good clue where it is going to be
in the future as more and more schools dumb down there CS programs.
