Functional Programming Patterns with Java8 with Victor Rentea

After leading 2 projects making heavy use of Lambdas and Streams, counseling many others at IBM, and teaching hundreds of developers at University and as an Independent Trainer, Victor will prove several best practices, patterns and anti-patterns he distilled over the years. All via a series of live coding exercises, like you've probably never saw in your life!

You will hear about: Bloated Lambdas, A Happy Predicate, Stream Wrecks, How to Kill The Biggest Bug, Monads, Passing-a-block, The Loan Pattern, and 5 Ways to Implement Type-Specific Logic. Of course, as a Clean Code Maniac, Victor will always strive for maintainable, readable, elegant code.

PS: You know, some Joe will maintain your Java8 code at some point. So let's just hope Joe would be a nice safe guy...

this guy is seriously on steroids..amazing !!!! it shows how much he loves coding and how much he enjoys the beauty of Java8

[nitinagrawal]

OMG...whenever I watch & listen to this guy, I always wonder how fast he writes the code with such clarity & focused thoughts...always happy to see his enthusiasm in his presentations.

2:03 1-/ Try to name your lambdas to avoid anonmous functions
10:57 2-/ Make good use of optionals. (ex. No nullable parameter, even Optional params)
17:48 3-/ Avoid "extends" by Passing a Consumer<writer> instead of using Template Method
27:01 4-/ %:Y## Bifunction On Enum :-8 ... No comprende ..
41:31 5-/ Clean code rules Sumup

His presentation style is not my cup of tea I have to say but the material he shows is very much worth it!

[minjee]

hes like a stand-up comedian in IT. actually like his enthusiasm

[antonyinjila]

I think the video has been fast forwarded when he writes code. This guy is something else :)

[hemonthm]

Salute you sir!!. Your talk is really interesting and worth watching.

[venkateshgurram]

if we write programs like this then one day is enough to complete project

[amazingvipul]

Good to see a Happy Coder. Awesome talk Victor.

[bonitokumar]

Most underrated video. Although he gives good examples, he should explicitly mention the principal behind the refactorization

[olarewajushowemimo]

Just seeing this and is really helpful... we keep learning

[LivenLove]

This was as interesting as a video game..for the first time everrr. 😊

[bhavindoshi]

Really this talk deserves to be best talk for Devoxx 2018.

[singhsankar]

how fast he is writing code and explaining.. amazing..

[SamuelGuebo]

Very instructive. By the way, is it just me or his typing is quite fast?

[samuelvishesh]

He's a SuperProgrammer, Superman 🤦

[nabiltaylor]

The last part just blown my mind. Hoppefully I was grabbing hard my chair.

[lewiswccful]

amazing presentation.
just wondering if last example could introduces cyclic dependency

[shadowgallery]

A revolution without dancing is a revolution not worth having.

[kennethcarvalho]

How to do that in a presentation within an IDE..you hold a key and the code comes out line by line....Please assist since I want to do a code presentation shortly..Thanks!!!
