October Java puzzles

If you missed yesterday’s CZJUG meeting, all the presentations will go up on the October page. For now you’ll find my Java puzzles slides there. I hope you enjoyed them and will take another look.

Next time we’ll definitely give everyone more time to read the problems. I’d also like to set the record straight about the puzzle “You Sort, I Sort, We All Sort.” Someone in the audience caught me off guard with a question about integer overflow during initialization, and I got the answer wrong. Initializing an integer to two billion doesn’t overflow. If it did, the compiler wouldn’t compile it. The overflow really does happen only when we take the difference between the big and small integers.
