'getObjects' returns a List object not an individual object (which is what you are trying to set the field to). If you are trying to set the 'schock' field in all Violator objects to 'true', then:
?
1
for (Object obj : getObjects(Violator.class)) ((Violator)obj).schock = true;
or
?
1
for (Violator violator : (java.util.List<Violator>)getObjects(Violator.class)) violator.schock = true;
The first one typecasts the objects from the list, the second typecasts the List itself.

Well, I take care of my elderly mother at home. So, my spare time, which is intermittent, but often, is TV, computer or jigsaw puzzle (wish I had a pool table, though).

Dan, do you have a job as a programmer? If so, what level of expertise are you required to know inorder to get employed? The reason I ask is that I want to become a programmer. I 'excel' at mathematics (for my age) as I am one of the best in my year, as I know you need to know maths well to program, but I do not know what level of skill I need to acquire, and what topics I need to cover. I have yet to cover networking, working with sql and rss in Java, and some other major topics. I am currently working on Graphics2D and BufferedImage along with other classes to make a paint program like GIMP (but worse as it is in Java and I lack the skill & time to push it to that level). So yeah. And another question: are there any 'professional' painting programs made in Java? Thanks in advance. PS Other people can give their opinion too!

I know it is a very saturated market, but I want to become one. And not in gaming development, that is even more saturated (and is limited in Java; use c++ for that).

I never held a job as a programmer (though I have done a little this and that for places I have worked at, as well as some personal requests). I do not have any formal training, per se, in programming. Ninety-nine percent of my programming knowledge I have acquired on my own (GWBasic>QBasic>Assembly>VisualBasic>Java -- I have touched on HTLM and javascript as well).
