What’s the current state of closures in Java?

Question

Does anybody know, if closures will be in Java 7?

Answer 1

It is unknown until the Java SE 7 JSR is created (presumably by Danny Coward) and an expert group is formed and the contents selected.

My Java 7 page is a good collection of links about Java 7 in general and has links to all of the closures proposals and blog entries:

And I maintain a Java 7 link blog where you can find links on closures and other stuff at:

http://java7.tumblr.com

And you might find my Java 7 Predictions blog post to be interesting as well if you want my opinions: http://tech.puredanger.com/2008/08/02/java7-prediction-update/

UPDATE: Mark Reinhold stated at Devoxx in Dec. 08 that closures will NOT be included in Java 7 due to a lack of consensus on how to implement.
