Does anybody know, if closures will be in Java 7?
At Devoxx 2008, Mark Reinhold made it clear that closures will not be included in Java 7.
Wait! Closures will be included in Java 7. Mark Reinhold announced this reversal at Devoxx 2009.
Belay that! Closures (lambda expressions) have been deferred until Java 8. Follow Project Lambda (JSR 335) for more information.
