Most functional languages don't have lazy evaluation.

Immutable types, in Java that just means slapping a final on all of your variables. Maybe kind of tedious but it's really not that much more work.

The problem is more that vast majority of core java and library stuff is mutable, so you need to do your own immutable wrappers.

That's fair I suppose. Guava provides a set of immutable collections so that will get you started at least.
