Thanks for video.. is stream are faster than old for loop ? if yes why?

Welcome! No, they aren't faster. They just help make the program smaller, succinct and easier to read/maintain. Theoretically, using parallel stream can be faster than for-loop, but only if the stream has large number of elements and there are lot of filters/transforms involved.

not always, butstreams are used for better read and less boilerplate code and are used for internal commands to do something with values and then reffer them to some another date type etc.

Even sometimes streams are slower than simple for loop if your data is not huge enough.

Let’s start with an example....! This is how this video starts, not even a single second of unnecessary content.. spot on .. exceptional 👏

The best and complete tutorial I've seen about Java Streams

I'm simply understood the concept now very well. The way of explanation is awesome. Thanks for wonderful diagrammatic explanation to easily remember the concepts. Thank you so much Defog Tech.

Excellent work! Thank you for taking the time to put this video together and for the clear explanation it contains.

Crisp and to the point as always. Keep up the good work! Really appreciate your videos 😊

Incredibly put together and very in depth! This guy is definitely getting a subscribe from me! Thanks

Amazing introductory video. Adding my two cents to parallel streams: Choosing between stream and parallel stream depends on various important factors and also the prerequisites. 1) Parallel streams internally uses fork-join(divide and conquer technique) to evenly distribute tasks to multiple threads to achieve parallelism. Hence the function/operation(intermediate operation) that is being performed on streams should be STATELESS(parallel friendly) else it will deteriorate the performance than a normal stream. 2) Breaking and merging of stream should be easy. For example an ArrayList is easy to break and merge than a linkedList.

Defog Tech is a great youtube channel for great explanations for Java Tech related stuff. Thanks.

This is the best and crisp video on Streams.. covered so much in short time and your audio is also soothing to listen , Thank you for all your hard-work 🙏🙏🙏

Very well explained. Thank you so much!!!

Awesome explanation! The figures @5:05 and @11:28 makes it so clear to understand.

Very nice video to understand streams with examples. I have been following your tutorials they always been amazing with such good content. Real time examples of streams. much appreciated.

Superb and clear explanation of multiple important concepts in 15 mins.. Thanks a ton..

Very helpful! I had 3 hours of university lectures and l didnt learn anything. I come to youtube and learned 100% of everything from the video! Thank you!

One of the best videos about streams. Thanks.

I always admire of ur work. You give more info in less time with good pictorial representation. You deserve more subscribers. May be changing channel name helps. Waiting for more content...

I do not know if this was done on purpose, but there is a mistake on the first piece of code: You want if ( min > numbers[ i ] ) at 0:10 . Otherwise, you would be calculating the maximal value. But this actually shows a useful aspect of Java Streams: less mistakes while writing trivial code.

Exactly, that's the usefulness of java streams.

Thanks a lot. You gave lot of information in less time as well as you did not make hurry in explanation and speaking speed. Amazing man. I just surprised that how could manage to impart good chunk of info in less time even you spoke at moderate speed, showed code examples, diagrams with explanation, simply amazing. Other good thing in your video is that you also covered Terminal operation in detail with clarity and simplicity of course here also you did it in less without loss of quality. Most of other tutorial skipped explaining Terminal operation part.

Thanks for the video.. Your tutorials are crisp and clear..

Excellent explanation ... Awesome.. Thank you so much.

Outstanding !!!!! the best video on streams I came across.

awesome explaination

Nice Explanation thanks

Best for revision of java stream api

Nice explanation

Hello thanks for wonderful and clear tutorial..worth a every second in the video. Please correct me if I am wrong, As per my understanding in stream API we can use multiple intermediate operation(lazy initialization) and single terminal Operation(eager initialization).

Awesome

You are the best…awesome explanation with great examples. Thank you, Keep going.👍

This video is very interesting. Although! The old code to find out the minimum element from the array The "if" condition is wrong. it's the expected should be numbers[i] ) > the code in your video will give you the maximum number.

Difficult sir, I will try.. definitely on my list though

About performance: 1 order of magnitude slower stream is.

I have a List of Java Objects, using Stream I'm trying to get a match of an object. If present then i wanna update it, else i wanna add a new Java Object into the existing List. Is there any simpler way of doing it?

Will the order of intermediate operations matter for stream to optimize them ?

Streams do not apply those intermediate operations until the terminal operation is not found. That's the power of streams, they are lazily evaluated.

@DefogTech

5 жыл бұрын

Agree about the lazy evaluation. Though we hardly ever pass around streams (without terminal operations), unlike Reactive Streams which are meant for that purpose. In official documentation, laziness is more about not evaluating elements which are filtered out in previous filter operation, (eg: sorting need not sort duplicate elements, if distinct() is used before it).

👍

1:25 but System.out is an object, why is it then a *static* method reference?
