What is the policy of dealing with answers that would become wrong after time? As an example, if I asked the question Does java support the Elvis operator ?: the correct answer today is no. The correct answer when Java7 becomes widely available will be yes.

What would be done in that case?

  • Re-tag old java questions with java5 or java6?
  • Keep them and hope people correct the answers?
  • Something else?

1 Answer 1


Edit the answer to say "As of version x, it is now supported. Previous to that, it was not." That's exactly why SO is wiki-like.

    The only difficulty is in keeping the answers up to date.

    @TXI I'm pretty sure for most topics (at least the most popular ones) we've got more than a few people who spend their Saturday nights making sure their pet topic is clean and up-to-date :)
