Lambda?
To help simplify coding, Java SE 8’s Lambda is coming to Java EE 9.
What does this mean? Lambda expressions are a syntactical feature of the Java SE 8 language (and lots of other languages, of course). Java EE is a set of standards, frameworks and libraries, but the language used to create JEE applications is... Java. So lambda expressions are available regardless of the JEE version, as long as you're compiling your application code with Java 8.
Have I missed something?
