java.util.Objects

[Thomas Oellrich]

It seems that parts of com.google.common.base.Objects made it into JDK 7:

Congratulations! I was wondering what the consensus was on java.util.Objects#requireNonNull which seems to clash with Preconditions.checkNotNull or is it too early to say?

Cheers

They don't clash; they provide effectively the same functionality with
a slightly different interface.

Any other parts of guava that made it into JDK 7?

As far as I know (and maybe I'm wrong about this), I don't think java.util.Objects was based on Guava's Objects class. I think it's just a different class called Objects that happens to have some methods with the same functionality (because they make sense there). I find requireNonNull() being there kind of odd, since a class like Preconditions seems like a much more sensible place for it. I guess they decided requireNonNull() was worth it but that a more full-featured class was not at this time.
