Exploring Java 9: The Key Parts by Venkat Subramaniam

[@rohit250289]

If I may say so - Venkat is the 'hero' of the programmers..

[@OmyTrenav]

Venkat is great! Educational and entertaining.

[@JavierGomez-xl9us]

LOL

[@elephant742]

Best stand-up comedian.

[@rmabini23]

I really like Venkat, I hope you continue educating us with new features of what-ever is new and exciting. Please

[@jamieguthrie1760]

@1:31:05 this guy is legit a comedian! 😄

[@ourahouamine5076]

You are the best for ever Mr Venkat

[@ledwinson]

Thank you 🙏 Venkat... great teacher 👨‍🏫

[@MsJavaWolf]

Good talk. It seems to me that more complex iteration really doesn't look much cleaner in the functional style though. The example at 29:40 takes pretty much as long to write as the loop and you can have the same problems, like off by one error. Functional programming is the new hot thing now, but I feel like it will be overused and potentially introduce new problems.

[@vetri_vel]

Thank you

[@thinkingaloud1833]

It feels kinda strange when you pass stream around, considering streams can only be consumed once.

[@spice940]

It's useful when you want to maintain immutability. The consumer of stream can collect it into different object and reuse if they need to use it multiple times.

[@TCSBEAST1]

Thanks for uploading, yet another useful session by Venkat

[@spice940]

1:18 modularization

[@hellowill]

they didnt call it limitwhile for consistency, but because takewhile is more clear

[@commel]

Isn't he the hilarious Scala guy we loved back then??

[@web3tel]

Nice presentation, very useful, thanks. It still amazing how behind is Java after other FP languages

[@christopherstamp9716]

It's not a functional languge... Its an imperative style based language but trends change

[@clray123]

Adding more and more crud to what used to be a simple and enjoyable language.

[@nitinagrawal6637]

I am really not sure why people are trying to compare Imperative & function styles. And trying to meet these both ends. In the start every change looks good & refreshing but I fear that soon this will become a mess, if it continues.

[@uditgupta6997]

Amazing talk

[@USONOFAV]

anyone knows what editor or IDE he is using?

[@ratunawartejas]

Even I am also wondering the same 😂

[@amanpandey6427]

this man is awesome

[@YogeshShinde31]

Getting Runtime error is more fun than getting compilation error ..

[@mmcooe]

I had a question, does steams have a higher code complexity than imperative styles such as for loops. Also do they require more space an ram to execute?

[@jvsnyc]

Because of the lazy evaluation, they can have far less memory to do the same tasks. Like the difference between reading a line at a time and entire enormous files difference in the extreme cases.

[@LemonChieff]

``` IntStream.iterate(0, i -> i +2) .limit(3) .forEach(System.out::println); ``` Isn't exactly an idiom. While: ``` for (int i = 0; i < 6; i += 2) System.out.println(i); ``` very much is. So maybe it's just a bad example or maybe I just don't like it. I don't like it when I have to ask myself what a function does. That's never a problem with imperative programing because the code says exactly what it does. It's not only harder to understand it's also longer.

[@hellowill]

en.wikipedia.org/wiki/Declarative_programming literally the opposite

[@chaitanyayanamala845]

ok

[@cschandragiri]

The module part was bit confusing in the end!

[@mohdshoaib4350]

Guys I was trying to compile the same examples as demonstrated in the presenatation. While using the com.agiledeveloper module from the com.agiledeveloper.first module , using the same build.sh file as shown in the presentation, I am getting an error : 2_using_module/com.agiledeveloper.user/module-info.java:2: error: module not found: com.agiledeveloper requires com.agiledeveloper; If someone faced the same , please help out. I have jdk 10 and platform is ubuntu. Many thanks Venkat sir for a beautifu lecture.

[@mohdshoaib4350]

Well I figured out the mistake i was making. Not giving the correct path. :p

[@MaFd0n]

what IDE does Venkat use?

[@christopherleong3992]

He's using TextMate

[@Anbu_Sampath]

Isn't devoxx 2017 in the title??

[@behaardenbosaap]

Title is wrong, the talk is definitely from 2017.

[@Anbu_Sampath]

Frederik Van Hoyweghen yeah that's correct

[@jeyosman1]

process(stream integer stream) is already in java 9 is red under line

[@soumitripattnaik]

57:54 what is that Sleep.sleep(5000) ??

[@JackDubs]

soumitri pattnaik It's a separate utility class he wrote to remove the ceremony of the try/catch for the InterruptedException that Thread.sleep() traditionally requires.

[@soumitripattnaik]

Jack Weldon Thanks :)

[@abdullahmuhammad2010]

Can somebody point what is that IDE?

[@saiganeshmunduru5472]

jshell

[@JavierGomez-xl9us]

20:53 "in software development we should never be consistent", LOLOLOLOL

[@clray123]

The extra syntax tricks will be used by few, but will be a permanent mental tax on everyone who has to understand them.

[@briansupra7]

[@iamrigank]

21:00 "In software development we should *never* be consistent" .. take that! xD

[@spice940]

How come audience was so dead? Some of his jokes were really funny.

[@soumitripattnaik]

These talks are like drugs for my brain.

[@LordByron778]

Too much, and little practical usefulness in real world applicability

[@nir8924]

1:54:00 coding has never been more LGBT friendly 😂

[@clray123]

The whole streams thing should have always been an external library which only weirdos would use, not part of the language. You don't need 10 different syntax variants to implement a damn loop and whoever is gonna read your exotic loops after you is gonna curse you for the "creativity".
