I have been programming for about 30 years and have a software package for livestock auction markets I have been supplying since 1980. I am retired and enjoy programming bits and pieces of software just to do it. I have very little Java experience and am trying to get a grasp of it. As a matter of fact my experience in object oriented programming is very limited. The auction market software I wrote was first done using C basic and was I redid it in the 90s using C.
