«JSR TBD: Project Lambda Lambda expressions (informally, "closures") and defender methods for the Java programming language»

Welcome to the sixties, Java!

Sorry, I couldn't help it >:D

That's a deferred feature. It won't make it into Java until version 8.

Oh, in that case, welcome to the 50s ;)

No no, closures (basic) are part of Java 7.
