Delicious Integrated Into Yahoo Search Results. Well, according to TechCrunch they are. I say 'according to' because I can't see any sign of it when I do the same search (java). Yahoo have slid this in quietly and there's just a little Delicious square icon with 'x people bookmarked this page under <tags>'. Makes sense to me - we've already seen FuzzFind incorporating Delicous results into the mix, and since Yahoo actually own Delicious you'd expect them to start using it sooner rather than later.
However... it's annoying that I can't see it! I'm still getting the plain old Yahoo results.
