This is hands down the best Java playlist I've watched in the last 10 years! The clarity, depth, and practical insights it offers are unmatched. I genuinely believe this could be a game-changer for anyone aspiring to master Java. It would be a truly generous act of kindness to make this playlist freely accessible, enabling countless learners to benefit from its brilliance. Thank you for creating such an incredible resource!
thanks a lot
Out of all the tech channels I follow, this is the only channel where I provide comments. You're content is always in depth and easy to consume. I can understand you put lot of efforts to get here.
Request to please see if possible you can allow all to watch your videos and not just the Members. Thank you once again for sharing your knowledge.
Thanks
Salute you brother, now I will watch only your videos from now... Too much Deeply with simply explained 😅😅 Real Java Developer ❤
I have watched so many videos on this, but nowhere did I understand. Because of you, sir, I understood it very clearly. Thank you so much for your clear, easy-to-understand teaching.
Those who are looking for a good video on Streams, you can go ahead with this for sure. Excellent explanation with examples in detail. Appreciate your efforts, Shrayansh😊
Today I got clarity on stream just because of this videos, literally saw a very first videos of yours and also planning to watch other, really very informative and beginner friendly, Hats off, Keep it up 🙏🙏
me too
ONE OF THE GREATEST JAVA TEACHER
TRULY GOATED 🛐 THANKS MAN
Really awsome and helpful content Shrayansh !!!! . Keep up the good work.
25:06 here in the the map() method we pare passing a function where Stream is the type it is getting and Stream is the return type.
but in the body of the map function we are mentioning only type
** Stream map(Function
bachpan k Sapna pura ho gaya, streams padrone k. Thank you so much.
How was the video buddy, is stream totally clear
@@ConceptandCoding yes yes.. all clear. Need to implement with day to day coding, I believe that is missing with streams in my case.
cool, whenever you try to use for loop, change it with streams, it will help you to get some hands on experience with streams quickly.
I knew before that only you can make justice to streams explanation and you did in a style!. Very much clear. Now I can start implementing with full confidence in my daily work. Thank You So much. Hope same from the multithreading explanation.
Thanks buddy, it's was a huge topic and lot of pre work done to make sure that it's understood in a correct way.
Thanks for the feedback, means lot to me.
I have to say, summarising java streams topic in an hour is pretty hard. This is impressive.
I hope you do a dedicated video where streams is used in different scenarios/questions. Learning with more real life examples would be really helpful.
Yes, buddy. I will definitely plan for it.
Can you plz give feedback of taking membership of this channel.
Thanks
thanks for the appreciation
Very informative and explained in an understanding way. Thank you.
Awesome. You took lot of efforts. Very nice explanation.
Man - you are killin' it!
Thank you! You made it very easy.
Your a Legend 🎉❤
Thank you so much sir, easy to understand and remember how to use Java 8 functions.
very helpful..great service for the community.
You have explained the topic in a simple and clear way. We have no difficulty in understanding it, but I have one suggestion for you. Before you start the topic, can you make us curious about why it is important?
Nice point buddy. I will do that for sure
Awesome 😊😊
Solid h boss..super explanation
Such a wounderful explanation..Thank u so much
thanks
very good video Shrayansh on streams
Amazing content and Nice explanation bro thanks a lot
Great video!
Awesome bhaiya, pls post more on lld and java related topics
It would be more useful if you could share real-life use cases of how these intermediate filters can be applied.
30:58 , why we are not using terminal operation in this case of flatmap. Is it like we are just making stream but not making final transformed output from it ?
Loved it!
Good job bro
In college, I was only to the basics or mere of it. But now I am much confident of my skills. Kha they sir ap
Great explanation
Thanks
Hi shreyansh,
great explanation!!
I have some adhoc request that I found difficult to understand.
1. java date - hell lot of classes present to get current date with some format.
2. how exactly synchronization works what to put in synchronization(something) want to get into deeper.
3. what is exactly mean of java equals() & hashcode() why these exists and its internals.
4. java file - standard way to read/write files and I think there are 2 version of it java.file & nio.file
Please also plan to make depth video on these things and also let us know if there are good articles we can read about it.

Hi Shreyansh, This is very helpful
can you please help me in understanding what makes a stream lazily evaluated and what is the advantage
Hi Shreyansh, one suggestion you could have not included the data type of parameter. That would have been still concise.
Anyway great video, thank you!!
Thanks, Bookmark 01:04:14

Is there any benefits to mention the data type of current stream variable?
salaryList.stream().filter((Integer sal)->sal>3000).count();
or can we simply do this?
salaryList.stream().filter(e->e>3000).count();
Very good explanation of steeam. i have one doubt, what is difference between Function.identity() and (i -> i)
at 19:06 Why are you typecasting inside the filter ((String name)) is this necessary ?
It is optional. But better to do it as the filter takes a predicate of Generic type()so when we say (String name) so T is now strictly of type String and cannot accept any other data Types as input. It is not type casting it is defining the variable type inside a lambda expression.
Thank u so much sir
I purchased from Udemy, but materials not allowed to download from Udemy, is there any possibility to download the content?
sir some videos of playlist is accessible to members only if it is done by mistake please make it accessible for all please
at 14:45 -> I tried Stream arrStream = Arrays.stream(arr); in intellij, its showing Incompatible types. Found: 'java.util.stream.IntStream', required: 'java.util.stream.Stream',
when i typecast it like Stream arrStream = (Stream) Arrays.stream(arr); its compiling fine, but failing at the runtime saying
java: incompatible types: java.util.stream.IntStream cannot be converted to java.util.stream.Stream
Can you please explain @Shreyansh
Did you use int arr[ ] instead of Integer arr[ ]
What are all the other methods we have similar to peek... Like i just want to know what are the methods which wont invoke till full stream availability?
none of the intermediate methods will be called until the ternary method is invoked
Sir please upload micro services and there implementation
Can you provide drive link or something for all the codes and notes of all videos and topics, it will save a lot of time. Also when we can expect multithreading video?
Pls check the description buddy.
Next topic is Multithreading only
i did not get this
just because the order of stream elements is in decreasing order how come the minimum element is 10 out of 10 7 4?
im confused af rn!
val1-val2 is the increasing order and val2-val1 is the decreasing order right?
so the min should stay the same right or is there a typo? shrayansh bro do u mean it is max?

Sir i want your suggestion
I am in third year i dont have much friends i came to engineering college which is very far from my city day by day Acdemic pressure not able concentrate on studies and placments in these college are not so good i am not able to learn new skill now what should i do dialy i am getting thinking too much and getting tension about future not able to think about present what
Hey Shrayansh, for Java 8, multithreading in java, i want to go through indepth for internals etc. Can you suggest any good books, articles or any other alternative for the same, though your videos are gem!
Try head first Java once.
sir , if stream is taking more time than parallelstream then why .....we are not using parallelstream mostly..?
it is faster, but with parallel processing many other complexity comes into the picture like thread safety and Complexity.
so use it when really need it.
Hi Shrayansh, not able to see the full notes from link, please look into it.
It's opening for me, can you please try once again
Bro why all the previous videos are "members only" ?
Hello Shreyansh, Not able to see the notes from the link. Please look into it. Thanks
These notes can be very important for the revision before interview...
I will check and update the link buddy
pls check now
@@ConceptandCoding Now able to see, Thanks Shreyansh
perfect.
10 and 4 will be the answers for max
Thanks
Note URL in the description not working
Will update the link by tomm
pls check now
Most of the videos are not locked I know you have worked hard for creating the playlist but most of people leave the playlist in between since most of the videos are locked. May be future if you thinks please unlock it ..🙂
how to pay through paytm/phonepay?
try through phone
@Conceptandcoding Thanks For making it simple. I hope you will cover where streams is used in different scenarios.
hope you find this video useful, sure will plan for it.
⭐⭐⭐⭐⭐
Can't access the notes .
hi, notes link i have shared in member community section
why lock some streams there's so many free contains available in
sorry did not get it.
😂😂Collection of data or data 1:51
Ye video play kyu nhi ho rha
its still in processing seems, wait for some time, its will be available after few minutes.
Stream.Builder streamBuilder = Stream.builder()
.add(1000)
.add(2000)
.add(3000);
this is giving me Incompatible types. Found: 'java.util.stream.Stream.Builder', required: 'java.util.stream.Stream.Builder'
Video quality limited to 360 p only
It's processing, in some time it will be available in 4k too, just now upload completed buddy
Please not use dark theam
I like it darker
