[@StefanHanrath]

An important concept but also an enormous increase in state space for your program. It becomes exponentially less simple to debug and reason about your programs runtime state when you take imperative / most OO languages into multithreaded code

[@shandilyacodes]

That's right! Multithreading should be used cautiously only when there is a absolute need. But in the cases where it's needed, it's a really useful and powerful and can work wonders to the performance.

[@StefanHanrath]

with high traffic concurrent code its almost inevitable to refactor towards immutable data structures and message passing, at that point why not try out functional programming 😅

[@tarose71]

It seems to me the intention behind the naming of the join() method, is that a thread is asking to join its immediate parent that called it, in terms of process execution, and this is also likely related to the Set Theory & databases concept of a logical 'join' operation ... so for me, it is intuitive if you think about it in those contexts, which are useful so long as you understand this historical & related field referencing going on, because it means we can also quickly think to look up those concepts in related fields where the name of the function is telling us that this could be useful ... whereas, the naming you suggested, while more literal, is more cumbersome to type, and doesnt connect us to this other relevant information

[@blackbeard3449]

The join terminology comes from the fork-join model for multi threading. Basically a thread can be forked into multiple threads which can later join back to the original thread. Wikipedia has an article on it.

[@tarose71]

@@blackbeard3449 which in turn comes from the things I said ... I was talking about the origin of the term from a far broader perspective which does relate to what you said, but also relates to many other concepts ... I wouldn't rely on Wikipedia, a lot of it's written by a younger generation more often than not who have NFI what came beforehand ... Wikipedia is only really useful for individual statistics like the land surface area of a continent or something of that nature which they'd struggle to get wrong, for everything else it's a bit shite

[@shandilyacodes]

Thanks for sharing your perspective on the concept @tarose71. I do agree with you, it makes sense when thought in that particular context. What I meant was that the term doesn't sound very intuitive to me if I am starting newly with the multithreading. For example, when I see run() method I know for sure the or atleast have this mental assumption that this particular block would be executed in some way by some one, even before having learnt the concept about run() method in context of multithreading. Thanks for watching! :)

Hi Ramendu, Is multithreading still maintains concurrency in multi-core or multi-processor ? Or it will be in parallel execution here?

[@rahulyadu1326]

is multithreading achieved by concurency or by parrallel execution in java . can we contorl whether multithreading is achieved by concurrency or parralellism in java

[@shandilyacodes]

I couldn't understand the question fully but I'd try to answer on the basis of what I understood In Java multithreading can achieve both the concurrency and parallelism. For the case of Concurrency, Multiple threads share the same CPU core, making progress by switching between threads. Useful in case of for I/O-bound tasks. For the case of Parallelism, Multiple threads running simultaneously on multiple CPU cores, effective for CPU-bound tasks. Thanks for watching! Happy learning.

You are thinking of a hyperthreading, which is a feature on intel cpus, it is not the same as multihreading which is a software concept, Multithreading does not require cpus with hyperthreading.

I understand your sentiment. Even if you are not familar with Java, the concepts atleast are transferrable to other languages which implement multithreading in some way or other. I am sure watching the video will have some value if you wish to learn multithreading or revisit the concepts. Thanks!

[@moments00000]

Some people hacking is just funny. What do u think about it?

[@HarshKumar-rk4zm]

I think by while naming join method they are thinking like this : public class JoinThreadExample { public static void main(String[] args) throws InterruptedException { Thread one = new Thread(() -> { for(int i = 0; i < 15; ++i) System.out.println("Thread 1 : " + i); Thread innerThreadOne = new Thread(() -> { for(int i = 0; i < 20; ++i) System.out.println("Thread 1 inner : " + i); }); innerThreadOne.start(); try { innerThreadOne.join(); } catch (InterruptedException e) { throw new RuntimeException(e); } }); Thread two = new Thread(() -> { for(int i = 0; i < 25; ++i) { System.out.println("Thread 2 : " + i); } }); one.start(); one.join(); System.out.println("Done execution of both threads!"); } } thread main : ----------------> one.join() thread one : ---------------> innerThreadOne.join() thread innerThreadOne : -----------> thread main ----------> finish (Kind of joining two threads)

[@shandilyacodes]

This indeed is a correct way of interpreting the join concept. What I meant to say in the video is that it's not very intuitive, specially to someone who could be reading this concept for the very first time, without much context. Thanks for watching.

ExecutorService executor = Executors.newSingleThreadExecutor(); -> I am using jetbrains jbr 17. when I compiled, it shows error like Autoclosable is not implemented in above. In this case, how come it shutdowns automatically. It didn't work. so I terminated with manual shutdown by writing executor.shutdown. can u help me in this?. which java version u have used during recording ?

Hey! Glad to know that you are writing code along to learn, great step :) To answer your question, I am on Java 17. However, this should work for anything which is Java8+. Still if it's not working please check the settings in Intelli J. Below are the steps 1. Go to File > Project Structure 2. Check the Language level and ensure it's more than Java 8 Apply, save and re try! Still if it doesn't resolve the issue then File -> Invalidate Cache and restart. Let me know how it goes. Thanks!
