Hey man! Last summer I spent my vacation in Florida watching your channel; wrote a cool game. This summer I'm on assignment in Germany, and I'm back to watching your channel again. You have the perfect way of teaching Java! 10-15 minutes, examples, fun. Just great.

This was very useful after spending a couple days learning the basics of threads. If I began everything with watching this video, I wouldn't have known what was going on

by far the best java youtube channel

your playlists are amazing . thank you !

I love your channel, thank you so much. You make things so concise. I come to your channel for every topic in my Java class and view the videos on it before going through my professors provided resources. It helps me tremendously. Bless you, my guy.

Thank you! I appreciate all the explanations and examples!

this teaching saved me one day of exercising on pdfs about threads

This video is extremely helpful and not hard to watch at all so far. I need this information but got tired of seeing 3 hour long videos drag on. So far so good. thank you for providing this content to me. I need it for a mod I'm trying to build.

I was wondering something about the run method. Why is it not always necessary to implement the Runnable interface? I often see threads getting created with the Runnable interface or the corresponding lambda expression. If the Thread class already has it's own "run" method, why do people implement the Runnable interface seperately?

Thank you friend!

Excellent video. Semester just started and this video really helped me out a lot man!. Please be sure to continue making more videos. Thanks

Tnx bro you are the best

I used thread in Client and server project I made. If many Client need to connect to one server, I created many thread to handle many different Client.

thx a lot bro

That's cooool!

So I guess this is normal. But I still got confused. Because when thread2 starts you can no longer know for sure in which order things will happen. Sometimes thread 2 will finish before you have time to check if it is running or how many threads are running. And sometimes it will still be alive when you check it. Try adding a few more printline statements in both threads. Quite interesting to see how it will sometimes execute one line of code from one thread then jump to the other thread and so on. Also when making thread2 a daemon thread there is actually no guarantee that it will have time to execute all of its program before the Main thread finishes and thus shuts down the program!

amazing

Two thumbs up! 👍👍

Hey thanks But at the second println statement of thread.active count, I am getting 1 sometimes and 2 sometimes Why? I have started the thread 2 also

Liked, by the way , there are so many people

What is the relationship/difference between threads and methods (and classes)?

@tharinduperera8758

Жыл бұрын

Methods are actions that need to be taken place.. you can implement anything to do within the method. Let's say you need to execute that method 5 times in parallel. Then you can use threads.. threads will execute your method number of threads you have defined simultaneously.. if you did this using a loop it will execute one after another. Threads likes number of people doing the same function at the same time..instead of one handling the heavy load , multiple threads can handle the work load faster and efficiently with the cost of memory usage. And as bro taught you can use the thread execute the method or certain function with a certain time interval and so many other functions

if i set thread2 to daemon, it did not show up the message, that it is a daemon thread that is running. I needed to add thread2.join; after the thread2.start; statement, in order to execute the run() function of thread2 somehow

My teacher didn’t taught me anything about daemon thread. Now I know something such as GC ‘s thread is a daemon thread. But there are still more daemon thread right? Could you list them?

@BroCodez

That one was the only example that I could find that I know of. You can make a user thread a daemon thread and the benefit is that the JVM does not wait for Daemon threads before exiting, while it waits for user threads, it does not exit unless all the user threads finish their execution

@girl6994

Bro Code but if JVM does not wait for daemon thread before exit , that sounds a little strange. But wait, I asked my teacher just now, he said in Chinese it calls 守护线程, which means thread protector thread, which means he will die if he’s lover dies.

Bro Code I understood. After your explanation. I didn’t know daemon thread well after that class. At that time I was very confused about why there is something calls daemon thread , but now I understood. Because Daemon threads do background task, and we don’t want JVM to wait to exit for daemon threads. No wonder it calls 守护线程in Chinese. It is a interesting translation though.
