17.11 Stream API in Java 8 Tutorial

[@LobhoGil]

I have seen other of your videos, and they are usually really good. This one was kind of confusing, jumping from one thing to another. I got the idea, and thanks for that, but watching your previous work I find this one unplanned.

[@adityadarekar3963]

Agree!

[@sunnyk794]

Not organized

[@poojasahu8667]

You are just incredible in explaining things in very easy way. I want to request you to please make video on SOLID principles in Java.

[@meheralok]

All your videos are the best in their nature. This is one of the best java8 tutorials available. Thanks a lot.

[@abhinavdadhich2311]

best explained i have many many confusions and only this video clears almost all

[@pawebugiel319]

awesome explanation

[@ayanaashree]

This is the best java video. You make it so simple.

[@vivek1857]

What an Awesome explanation brother !! keep doing a good work, there will be evil people around who would not like anything and keep criticizing this but don't worry about them, god made them check your patience !!,thanks to them too :) !! Well done !!

[@bittooaggarwal5776]

sir, this one was little confusing. I am following your playlist and reached till here. I wanted to give my honest feedback, but still thanks for taking your time out and making this tutorial.

[@kalyanraju4251]

Really helpful .Thanks so much for sharing your knowledge 😊

[@tareqislam8644]

Sir your teaching quality along with your speaking style is really amazing. :D

[@amanvikram04]

Naveen is a good teacher

[@SaravanaKumar-yh2pf]

Thanks

[@kush92296]

I see all your videos of JAVA 8 at 1.5x speed it helps to focus more.

[@thotamounika5633]

Thank you for the explanation! I have one small observation. In the last comment related to are streams reusable? in the background code, we are not invoking forEach on stream() but instead the syntax uses method reference. correct me if i am wrong. Sorry I see here the reference type is Stream itself. That's the difference.

[@rishikeshkmr]

Best explanation over the internet!

[@sarath6789]

Learning on the same day :)

great video navin garu

[@mithunkumarmajumdar8048]

very nice

[@bhaibhavghimire362]

Great Video!!You make Java so Simple man.Kudos!

[@kavyajain7935]

Very good work... Amazed some people are disliking...

[@divyeshkumarbalar7732]

It is better not to use parallel stream for small number of data; because, if you use parallel stream for 100 or 200 value and the operation on that data is not so big; jvm will spent more cpu time on managing the threads than actual operation.

[@vigneshv1517]

if someone ask me who teach you the java programming...i will say navin reddy sir......thank you soo much sir.....

[@ash-sy5el]

[@rameshnaidu8951]

If we want to reuse the stream we can convert steam into List. so its not a drawback, list is different and stream is different. Correct me if i am wrong.

[@amardhillon314]

thanks a lot for making this video

[@sivamunnaluri2263]

You mentioned parallelStream creates thread based on the core . stream() also create a separate thread

[@rohanpiplani841]

you are the best

[@biswajitjana9815]

You r great

[@mandeepsharma8305]

Great work. One question why to stand there in a video and talk? We could have background voices for the explanation. This way we could focus more on the code, not on the hand gesture.

[@MrSagar1654]

Hey, A suggestion : Anything new should be start With Why first they What and How. but here totally confused in this video.

[@shruthimarroju5055]

Please add. Video in description

Hi Navin , thanks for the these videos it really helped. I need your help, actually in one of my project I need to capture a video from Set top box and display it on jframe. Right now I can capture STB video using video grabber card "Easycap" and ffmpeg command line tool. I have googled but I didn't got success to capture STB content using Java. Please help me.

[@tareqislam8644]

Sir please make a video on Rxjava2 and Stream

[@joyanfernandes]

Oh... Boy, you gotta STREAM that video properly... Lots of jumping around, I reckon.

[@ershekharsolanki]

👌

[@learnlearn236]

too good.!

[@amirayoub5809]

Great job explaining but if I am going to click on wanting to know about stream() API. Stick to the current subject.

[@PoojaGupta-rp2js]

I believe there are Intermediate and Terminal Operations/Methods available in Stream API but you have used word Terminate Method which sounds incorrect. Not sure !!!!!

[@xx-tn2ue]

这口音，杠杠的～

[@snehaniranjana]

I see "System.out::println" in this video, Does this"::" in the statement mean anything? I haven't come across.

[@medbelaziz3818]

he said that "::" means that the println methode refers to th object "Out"

[@KazakovVsevolod]

System.out::println

Unable to find the second part of this video.

[@vyshnavireddy1121]

HI

[@umeshbhale3066]

I am not understanding Please make another video

[@zeliofern]

very basic tutorial only for beginners not for advanced ones.

[@pperez1224]

You have to create your threads because you have to understand what you are doing. Letting the system decide is inefficient , same as saying that since java use garbage collector you should not worry about memory usage at all. And thats wrong , the first thing a java profile tells you to do is to reduce useless allocation. Good programmer manage lifecycle themself. Lazy programmers says 'why should i have to think' ? IA is still not a reality mate, just marketing . And a processor is pretty dumb. Knowing the amounts of threads you PC manages ( hundreds .. ) its very unlikely 4 core are going to work for you only and if you will quickly end up having a streamParallel() calling a code with streamParallel(). So if the first uses 4 cores , the second can't . But the nested one in functional programming has to be evaluated first so at then end you only use 1 thread on the critical code.

[@TechnoSan09]

3:30 to 4:50 that's not correct the OS doesn't work like that we can achive multithreading in a single core itself also if there are n-cores there is no guarentee that it have n-threads it can have more than that all those things are manages by operating system

[@rupn9633]

usually your videos are good, this is not clear

[@joygamers8426]

Are you Indian

[@anjanisreegodisela9843]

This video is not clearly not explaining about stream API, lot of confusion in topic

[@sweat_gamer5540]

Looks like Navin is confused. Starting to explain one thing and then "Hold On"... Then jumping to another this... Total MESS

[@HumaraTuiTioOn]

Its not his fault that u r not getting it . May be u should concentrate what he is saying .

[@kumars5629]

Confused explaination

[@viveksharma7669]

Sorry Bro but I have to say this. I couldn't get much out of your explanation of streams.

[@daddashikamani]

This video seems incoherent and lacks a script with the presenter jumping from one train of thought to the next. Too verbose as well.

[@sarika9031]

Anoop Hallimala right.

[@PandeyRavindra1]

Such a stupid title of vedios, time waster last 10 vedios he didn't even used stream concept. Bogus

[@hyperborean72]

WTF he is talking? I can't understand a word from his mumbling

[@senthoorran]

may be pronunciation barrier. There r 153 likes and 4 dislikes. So it means there r many people following his videos to study. If u dont understand, clarify which way he can improve. Please don't just insult him. Navin, Thanks for ur videos and dont keep on doing. we r with u

[@marceloperezmaciel2173]

thank you for the tutorials Navim, just one curiosity, what is your native language?

[@marceloperezmaciel2173]

I can understand almost everything .. except when he talks faster sometimes, maybe because Portugues is my native language turn it more easy to understand

[@vimalsagar8079]

His native language is Telugu which is one of Indian regional language. In india people talks many languages

Dats because your mom dropped u when u were a child. Now u have learning difficulties. Stop projecting it on to others.
