In today's video we're going to explore Java Collections, a critical aspect that any Java Software Engineer should master.
We're going to learn about Java Collections Framework, Lists, Sets, Maps, built-in algorithms and many more!

Must helpful video I have watched about collections!
oops most
Thank you! Stay tuned for more content!
not much told about comparable and comparator witch is massivly used with binary search and other stuff
Good point, will keep that in mind for a future video
Good video. Just started learning about OOP and using constructors yesterday, and this has given me some perspective on some of the behind the scenes systems and in-built functionalities that I haven't got to yet.
Thanks for sharing man.
edit: just wanted to add a small piece of constructive criticism, please don't take it negatively, as the overall quality of the video is good.
From what I gather, while there were many helpful examples in this video that showed the each system in action, I think the overall distribution of information could have also had some more moments to focus on the Wikipedia articles you mentioned-nothing long-winded, maybe just some highlighting some of the key systems that you covered for each of the 3 parts of the collection.
That's all for my nitpicking. Be well and keep well.
Any feedback is welcome as long as it's provided with good intentions, as you properly did in your comment. Great suggestion, I can make a new video about red-black trees in the near future, I haven't included it right here because it was not in the scope for this video, but I'll definitely consider it for a future one. Thank you and stay tuned for more content!
thank you! very useful as my textbook did not do such a good job in explaining this

Thanks! Sure, I’ll make a clip to show how this can be achieved

//Not sure why so little subs, makes no sense...
sub++;
while (sub != 1000000) {
sub++;
}
damn
r u okay r u speaking so fast for
Sorry about that, you can slow down the video
your telling very fast can u tell slowly
I'll consider that for the next videos, thanks!
Slow the video
If it's really required, you can change the playback speed in UA-cam.
I think LinkedList.remove(index) and LinkedList.remove(value) takes O(N) since they require traversal of the list before removing
Yes, that's correct! I also mentioned that in the video as well
Thank you so much 🫶🏾
You helped me more than you can imagine.
You got a
New follower.
Thank you! Glad I could help!
