Hi again,

A great number of subscribers are on holiday at the moment, but to those that are not, thanks for sending your answer to the puzzle. Approximately 70% of respondents had the correct answer, which either means that the puzzle was way too easy, or that the correct answer was also the most obvious one.

As a short follow-up, here is a variation of the puzzle for your amusement.

What is the output of the following Java snippet?

public class Puzzle3 {
  public int test() {
    int i = 0;
    try {
      i++;
      return i;
    } finally {
      i--;
      return i;
    }
  }
  public static void main(String[] args) {
    Puzzle3 p = new Puzzle3();
    System.out.println(p.test());
  }
}
  

And here is the multiple choice again:

1. The code does not compile
2. The code compiles, but throws an exception
3. The code prints "0"
4. The code prints "1"
5. The code prints "2"
6. None of the above
7. All of the above

I expect the split between correct/incorrect to be similar to the previous "puzzles", since the question is so similar.

Kind regards

Heinz
