Why does buffer operator return Flux and not just Flux? Flux itself can hold more than 1 elements then why it needs to store a list?

[@gajavallisupriya6718]

so as the return type of collectList() is Mono so program will wait untill we print result .even if we don't write code for "press any key to end". correct me if I am wrong

Thank you Koushik for the course. Could you make a 'Code with Me' course for a Full stack application based on Java Reactive Programming?

[@updownftw]

Yes, we would like that

Hi Koushik! Thanks to your course!
I got the last task as take sums of every element with its neigbours, like 1+2 , 2+3, 3+4...
So my solution was like:
intNumbersFlux().zipWith(intNumbersFlux().skip(1))
.map(tuple -> (Integer) tuple.get(0) + (Integer) tuple.get(1))
.subscribe(System.out::println);

I am not sure how take(n) works. I have flux with 5 objects, and have take(1).log().subscribe() , it only logs the first one and does not log the rest 4 . Does take , only takes the given number and finish ?

[@kaushikravikumar7472]

Excellent video! Can you please share what IntelliJ theme and font you are using?

[@andraspoljak]

at 6:17 we can use .map(list -> list.stream().mapToInt(Integer::intValue).sum()) and it sums up all elements in the list

[@santoshkumar-mh1ke]

Thank you Koushik for the amazing work

[@drdzdd]

Great video as usual. Got me motivated

[@shivask5543]

👌!! Thanks!!

[@millfreedom]

Okay, this is okay, but you need to get rid of spelling continuously “okay”, okay?
Because okay is you parasite word, okay, and it’s a very frustrating one, okay, and this is not okay.

[@Java.Brains]

Okay 👍
