In my opinion, I guess that to be 100% sure,
you should add those comments to avoid breaking any 'must' requirement...
I'm not working on the GUI yet, but I was rather thinking about using
java properties instead of constant values. This will separate the communicates from your code and allows their easy modification and internationalization of (althought it is not a 'must' requirement I just feel it's right).
BTW: Check this out (
http://thedailywtf.com/Articles/Enterprise_SQL.aspx) - it's not related to communicates constants though, but it's basicaly about abusing of public constants.
The bottom line is a masterpiece ;-)
