Java Streams Tutorial | 2020

[@ibrahimgunduz34]

I just met your youtube channel while searching for something regarding spring security but after that, I watched some of your other videos as well. They are definitely awesome. Thanks for your work.

[@desarrollojava]

This is the best explanation I've ever heard. You have teaching talent man. Thank you.

[@pablodamiannovoarenteria4225]

This video complements what I was reading about streams, now is time to practice. Congratulations on this, you made so simple the example that you can save hours of reading for some people.

[@michaelandcarmenmaguire1108]

Your style of instruction is truly refreshing. Thank you very much for putting this together. It's fun seeing someone do something that comes naturally to them -- something they're passionate about. That's the vibe I get while watching this and learning from you. I'm definitely going to check out your courses.

[@jakovkusic4219]

Definitely the best video about streams on KZbin.

[@mertyertugrul]

I watch this so many times, thank you Nelson.

[@ЮрийАндрейцев-й1з]

so many times? sounds like Nelson awfully explained streams and you have to watch again and again to understand =) i'm joking. Nelson, great job!

[@mertyertugrul]

@@ЮрийАндрейцев-й1з No I just keep forgetting it 🙃

[@mingyungkim3680]

I’m really happy to watch this video. I understood ‘streams’ perfectly that made me annoying. thank u

[@trenvert123]

I'm glad your tutorials improved over the years. At least for the Spring Boot tutorial. Because this was rough.

[@florianseidel8574]

thank you for your work, Nelson. really appreciate it.

[@josephthecreator]

Extremely helpful. Stream APIs are so powerful, thank you for breaking this down!

[@CheeseStickzZ]

Nice explanation. But there's nothing wrong with using if ( multiple conditions ) it's actually faster in most cases

[@Alex-to5vx]

using if statements to make decisions are fine if its a truly binary decision, like if a function is passed a Boolean you can use an if statement because that Boolean value can only ever be one of the other. The functionality is predictable and expandable. However if you are using if statements to make decisions that are more complex all of a sudden you have code that is much less maintainable and prone to errors with any future modifications to the code or requirements of said code. Defining decisions through dynamic dispatch is the proper way of making decisions nowadays even if it is slower because it allows the code to be robust across time.

Thank you Nelson, always helping the community!

[@damahelouni2720]

Wow, thank you very much. You explain so well and easy to understand. Greetings from Germany 👍🏼

You are welcome :)

[@suwatchainanchai6637]

Thank you so much for your tutorial. It help me reduce a lot of code line from doing imperative approach.

[@eddiemarxmallmaalvarez1134]

I'm Latinoamerican and could say that Great video man, it's awesome!!

[@RustySilver-w1q]

Thanks Nelson, I'm appreciate this vids, because when I finished my formation course just learn the base.

[@ankit-jangid]

Explained very simply and cleared doubts. Thank you so much Amigoscode :)

[@barryalpha4484]

This is the best explanation that i have ever had. thank you a lot guy for this beautifull job.

[@abrehamish]

Thank you Nelson for excellent expalnation.

[@608raju]

the way you explained is clear. good luck

[@amigoscode]

Thank you

[@moodydog9960]

I think with the getAge and getGender in the sort expression, you need to flip getAge and getGender, i.e, do sort by gender first, then by age.

[@Netalon]

Thank you Bro ! Finally i learned streams in Java

[@cod3rhandl3it]

Articulate, informative, and succinct - WELL DONE and THANK YOU!

[@peytonpeck]

I was looking for a good video explaining/showing some methods in #stream(), and this was just awesome. 10/10 good job!

[@teofilomassinga7528]

Thanks, Nelson you are a wonderful teacher.

[@Hianfita]

Excellent video, stream really are insane! Your explanation was mighty understandable. Valeu amigo

[@tshepo2japhta28]

Man you inspire me ...keep them coming

[@amigoscode]

I will

[@FP_95]

Thanks man! Your content is AWESOME! Cheers! :)

Thank You, Nelson. Your videos are very helpful to me.

[@K.E.N.J.I.B.A.B.Y]

This was very infomative! I followed along with my own custom made class and I learned a ton! Thanks a million!

[@simpleandminimalmaybe]

thank you so much for the brilliant tutorial. may i ask....., are you typing the shortcuts yourself or it is IntelliJ IDEA doing this. I am writing them down by the way for ease of reference. thank you for the effort you put into these tutorials.

[@mkli3459]

This is very very wonderful! Thanks a lot! 👏

[@TheN0odles]

Hey bro, grettings from Johannesburg. Good work, man!

[@AlinaKay47]

Besides this being a great tutorial, for the first time ever my non-american name is used in an example :')

[@anantpillai4656]

Seriously well explained!!

[@amigoscode]

Thank you

[@fabiovictorino350]

It's was amazing. I love so much yours videos.

[@ninobach7456]

in classical java fashion, complexity gets added left and right

[@fredericochopin]

Nelson, this is great stuff! Thank you.

[@MrZbieg1422]

Thanks dude. You just saved me some time :D

[@juanignaciorios4513]

Eres un crack!! Thanks and greetings from Argentina🇦🇷

[@DaRolla2016]

Hi Nelson, thanks for this. Can you please explain how to get images into your comments? Like // Imperative approach ❌ and // Declarative approach ✅ ? My IDE does not show them right like the Github Webpage does. But in your video your IntelliJ did ?!

[@coelho8276]

best video for java streams

[@peasantfolkhero]

You have my thanks, you are doing this very well.

[@IvanPallaresTrivino]

I see this all over the place in Java world but, why not splitting those chains in methods with proper names to improve readability? I think that would make Martin Fowler happy 😄 Thanks for the great explanation!

[@dmytrog6127]

Thank you! Very clear, very understandable, very comprehendly

[@amigoscode]

Thanks

[@prakhar.odyssey]

very useful video and simply explained. Thank you so much bro!!

[@hamza-the-big-data-lad]

Please, make a video on Map vs FlatMap. Thank you!

[@abulka]

You can do exactly this kind of thing in JavaScript and Python etc so simply, without the excessive syntax that Java needs.

[@gintoki_sakata__]

That's fine.. as long as it gets done

[@carlozuk]

Amazing video, can't wait to take the course

[@Jody-nf2bz]

Excellent class. Thank you!

[@prashantvaghela3337]

Thank you for this amazing video on Streams in Java. I would like to know your learning approach to new concepts. How do you learn about all these concepts? What's the secret recipe?

[@techBuffy]

Buy a book and study.. There is no magic recipe for building concepts.. Free Videos have limitations

[@gurushashank7863]

Thank you, Helped me a lot 😃

[@brunocardoso8246]

Appreciate simple and structured explanation. Thank you !

[@yeso3716]

I was wondering why the output of sorted didn't change after you added thenComparing(Person::getGender()) to the method at 9:00 ?

[@ImAmericanGangsta]

for thenComparing it should do changes if we have two persons or more with same ages so females will appear first

[@worldwide6626]

@@ImAmericanGangsta yeah it was a bad example. He should have sorted by name instead

[@ctx4241]

It'd be great to include explanation WHY not only how. Imperative > Declarative does not say anything to anybody. It is hardly shorter codewise then forE way. Point of streams is that the operations can be done in parallel with drawback that setting up stream takes some time. Therefore setting up stream for huge list is worth it because of parallel nature of operation, while this couple item long list you are probably just wasting time on typing I believe?

[@andresencolombia]

Great job Amigo.

[@iranmpc93]

You dont explain, do a show! thanks for the class!

[@aobaidi5626]

The best, brother

[@hansmustermann4206]

nice explained, but you must agree, that "thenComparing()" only makes sense, if the first comperator produces any doublettes, dont you?

Its tuned for performance too
