Jump-Starting Lambda Programming

"You've probably heard about the new Lambda feature that's going to be in Java 8. What might not be obvious is why Lambda is important and how you can use it effectively. This session re-examines familiar programming constructs, taking apart several simple examples and putting them together in a new, "Lambda-ready" (functional) style. It also shows how this powerful alternative style provides greater flexibility for structuring programs and easing the transition into parallel programming. Finally, it introduces Lambda itself, which is when it will become clear why the Lambda construct is important and how effective it can be when used in this style.

There will be no math in this session. Well, maybe just a little.

Nice choice of example showing a very clear progression

[ThuyNguyen-buge]

Thank you for all your hard work in making Java into a beautifully structural programming language that I'm so proud to write in.

Can I assume is that the Block<T> introduced at 33:25 was changed into Consumer<T> in official Java 8 java.util.function package? So the call "block.apply(num)" in fact should be written as "block.accept(num)".

Thanks for the effort and publishing the video here! Great introduction to the topic

[gourisankarkhatua]

Awesome.. Pretty interesting feature and going to be ubiquitous.

Lambda looks like a good thing...hope it serves the purpose i.e. letting the developers concentrate on business problems than iterating collections every time...

[jennythomasmathew]

What about performance? How good/bad/ugly is the performance of streams? Assuming no parallelism?

[zentura]

Will my old code still work in Java 8?  Is there a rundown of what gets broken?

Can I have this presentation?, because i'm going to translate it to Arabic as a lot of Arabic people interested in Lambda.
