Java Streams Tutorial | 2020

Java Streams allows you work with Collections/Lists like never before. In the good old days we use to define every single step (code) what we wanted to accomplish, we used to write a lot of code for something very small (The Imperative approach).
What Java Streams makes it easy to work with Collections and it gives you as a developer an API where you can ask what you want instead of defining the full implementation for the thing you want. (Declarative Programming)
If you not using Java Streams 😱 then you should take a moment and watch this video to learn more about it.

Hello Neloson thanks for your interesting and well explained concepts. please would like to know how to come out with printing only one property of the person after sorting.

[@cxrealzim8762]

Great content mate.

[@MrZbieg1422]

Thanks dude. You just saved me some time :D

Nicely explained. Nice work!

[@amigoscode]

Thanks

[@DarrelDavis]

Great explanation. Thanks much.

[@amigoscode]

Thanks Darrel

[@Pothanenos]

Thanks for the tutorial, it is concise and well structured. What about the performance of this method compared to the imperative approach?

[@amigoscode]

Its tuned for performance too

[@marcincylkowski3004]

Very good video! It is really helpfull

[@BrilliantMindsZw]

quite clear and understandable

[@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 ?!

[@andresencolombia]

Great job Amigo.

[@PapaSmurff660]

how would you change min/max if you are working with a generic type? in this case you don't have access to something like the getAge method

[@EmanAl-Murish]

Woow, thank u so much for this Amazing video

[@houariboumediane3536]

That was good man...thanks.

[@coelho8276]

best video for java streams

[@study-channel6301]

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

[@vpenywise]

4:19 - doesn't appear to be free anymore, but then again, I'm a few years late watching the video :D Thanks for the content nonetheless! I will also check your website and courses for sure!

[@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.

[@user-mn3iq2cs9n]

I had to switch my language level in IntelliJ to Java 9. I have Java 13 installed as of 2019. Is List.of method going bye bye?

[@johncerpa3782]

Great video!

[@aobaidi5626]

The best, brother

[@mnarayanan5363]

This is good content. Thanks

[@TinyEarthling]

Thank you, Sir!

[@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

[@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.

[@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.

[@senss3000]

awesome bro thnks ! we want more

[@vancuong8418]

Really helpful thanks

[@adamfaisal1750]

Many Thanks Dear Nelson

[@MatheusSilva-gx8sj]

[@Cavdar2012]

excellent! thanks a lot.

[@surajdas_31]

Nice explained,
by the way thank you.

[@amigoscode]

Thanks Suraj

[@surajdas_31]

Can you do anything with spring boot along project?

[@user-jj9sx6hh7h]

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!

[@ShaileshDagar]

Thanks, man!

[@ajitdas4515]

Awesome. Thanks
