The tool even is that good that you can generate source stubs from javadoc. I experienced once that we only got the javadoc from which we built the stubs to implement against. Not too bad but seldomly used.

It would be a good idea to leave out those kind of sentences if you don't want to raise tension. We all know that you didn't work "several decades" with java :) And stating that you have decades of experience in this area doesn't make your statements "more true". It will be still what you write that is good or not. I can't agree on your statement that there aren't professional java programmers that don't use javadoc. Quite the opposite in my experience. To me it appears this way: Documentation is only properly created if the source code is build for a customer. In this case the documentation is part of a contract. I didn't see that much documentation that was created by a developer out of his own motivation to do so. > In fact, when you get to a new java project the first thing you do is go > looking for any javadoc because that is often the only documentation that you > can find. > That is a fundamental difference if you are talking about documentation. In lanaguages like java you need to have documentation because you ususally don't have the code. So I would state that people programming java are forced to create more documentation which isn't that bad. > (When it comes to base classes there are of course plety of supplementary > documentation.) > > Thus, when I started to look att Smalltalk again and did not - and perhaps > does not still understand - some code I go looking for documentation. > And it is bad if can't find one. This I can fully understand. I myself do not tend to overestimate the use of documentation. To be honest I consider documentation a bad thing for now and then. But if you have the code and the code does not explain itself than you are in need of a proper documentation. To me that's _the_ definition of useful documentation. We know that this is a part that needs improvement. But it also needs people that are willing to do it because it is still open source. Are you willing to add documentation that you consider "is missing"?? > [I looked at Smalltalk in the early 90:ties and fell in love with it but > could get no consulting job in it so I left it.] > Sometimes you need to create those jobs as well.

This thing that enables you to write programs that run in every browser (you remember applets) was a good one. Followed by that thing that enables you to write cross-platform GUIs. Followed by the languages that deals with unicode and XML. Followed by EJB specification. etc. You name it. The very important rest is that they created a rich set of industrial grade APIs to deal with every single topic that emerged into this new medium network/internet.
