[@bukbol]

Thanks for the lecture on streams. Ive been a java developer for a long while now and u explained it a new way so thanks again.

[@bloom6874]

I liked your patience level while covering stream API. You go slow so that it could be easier for beginners to comprehend it in the first go. Great job. Thanks for the video.

And now KZbin gave me your tutorial. Niiiiiceeeee!!!!!!! PS: What about function interfaces? Can i ask you to make a short video about them and about method reference? Thank you. Best regards, your student Bogdan.

[@pt_trainer9244]

Thanks for this, I'm learning spring boot and security is making me so confused to the point of giving up. After a few months I still don't know how to add roles because I'm not used to the stream api. So the GrantedAuthority list confuses the hell out of me when assigning roles

[@dev-skills]

Awesome tip, 31:50: How to visualize stream operations using IntelliJ IDE.

[@gehadqaki]

Wa'alaykum Asalaam my brother, you are a teaching hero! May Allah reward you for your efforts!

[@ezechiellecynique5415]

Hello and thank you for your videos ! May I ask why at 33.33 on the left pannel we can see 36 values ? I tryed to play with the limit and predicate tu change how many perons that could be concerned and it's seems like java take an approximation. But the scope of the approximation depend of something that I can't find. Maybe I am wrong about something. #details haha :)

[@MadinabonuO]

Thank you, super useful!

Helpfull video..👍🏿

[@tinohouse7690]

Can you please do a course for Spring boot microservices, include authorization between services, communication pattern, CI/CD and deploy using Kubernetes?

[@piotrl8315]

Its amazing how simple programming became, but how's with the performance ? Is java is appropriate for functional programming ?

[@davidkeresztesi452]

good stuff man. thank you

[@santoshgujar5237]

Thank you, Sir, 🙏🌺😇

[@nightfury1678]

it's awesome , could you please make a video about how to organize code for Functional way Java project

[@ainigma100]

Thank you for your video! Can we use like comparison with streams? Imagine the following scenario: Get all people where lastName LIKE ..... Also, I am trying to Group By multiple fields and I am getting an error. Maybe I am not doing it wrong. Map map = cars.stream() .collect(Collectors.groupingBy(Car::getMake), Collectors.groupingBy(Car::getColor));

[@maxleonov7801]

Thank You!

[@znaidimahdi8885]

thank you very much

[@solangebrugnatelli]

First of all, thank you for all the time you are putting on these lessons. They are very helpful. I wanted to let you know that around 27:45 at line 20 you should change the limit to 9 (instead of 10), otherwise you risk getting 11 people instead of 10. You still get 10 people as a result because there are only 10 people in your database that are

[@asatbekxalimjonov4005]

Assalomu alaykum , just amazing and useful

[@andyvandenberghe6364]
