Well I'm sure a lot of students would be happy if you posted them on this forums, but I advise against it. The point of the textbook problems are so that students can learn how to program by completing the exercises themselves. If they just download it from you, they can pass your work in as their own and they will not have learned anything.

I suggest that if you do want to post the exercises, you should talk about how you solved the problem in detail (so it will help the students who need help and don't understand how to do it), and also stress in your program that it is your work (like putting comments in each method saying "Created by: ... ") so that desperate students don't just download your program and hand it in to their teachers.
