I am working my way through the latest Core Java for the impatient by Cay Horstmann. Does anyone know if there exists possible solutions to the purposed exercises? and if so where I could fine them? (added because I know someone will reply.... but of course they exist.)
Cay didn't provide "official" answers. At least one person posted "student" answers on github. For example, see here. And of course, you can ask here at CodeRanch about a specific exercise you are unsure of.
So far I created answers to the exercises that seem to work, I was really just looking for something to compare my solutions to. I will check out the link you provided and I appreciate the assist. I know I can count on JavaRanch.
