Hey. Just wanted to give you a thanks for making these types of videos. Last year during the pandemic I was ~5 months out of school and was struggling to find a job in tech. I randomly found your Spring Security tutorial video and did my best to follow along consistently day after day. I believe I landed my first job because of you and here I am again because I know your content quality is amazing. Thanks again!
Would love more advanced videos/courses. You explain things so clear and concisely that I'd love for you to break down more complicated concepts and libraries with focus on real world use cases.
This is what I want!! Coding from the beginning and explaining why you writing that code. Unlike to the other youtubers who already have codes and expects that you already understands it
This is directed at Amigoscode!! -i normally dont comment on tutorial vids BUT i am making an exception for this channel..You are doing a fantastic, amazing job. Do NOT stop what you are doing! Your videos are well edited and your presentation and narration methods are truly excellent-FAR better than most of the MORONS on youtube who make feeble attempts to introduce complex coding and software engineering topics to the masses..Seriously man you are doing our community of global programmers a big favor, and I appreciate it-just wanted u to know this..
Hey Nelson! Good explanation as always, great job! One remark on 5:22. For arrays it's O(1), not O(n) complexity to get specific element by it's place in an array.
Thanks for this content. I'm switching from Python to Java for a new job position. And this is very helpful for me to refresh and glance the data types in Java.
Thank you for making this. I'm doing terrible with my class because my life is so busy and my professor teaches nothing during class in practice, just powerpoints. I have to read like 250+ pages to learn things he's teaching like he assigns and I'm absolutely lost. thank you. this is amazing.
DUde you're awesome for this video. I took data structures and OOP in Java and struggled linking all the concepts together. You tied it all together concisely and in a very-well done manner. I'm confident stepping into LeetCode easies w/ a solid foundation. I can grind out the logic, but needed somewhere to start from :) I need to go over OOP concepts again but you made it a hell of a lot easier my friend. Best
Retrieving an element from an array is O(1), not 0(n). That’s one advantage over a linked list, for example, which is 0(n). Now *removing* or *adding* an element is where we have the complete opposite situation, where linked lists are O(1) and arrays are O(n)
The latter part isn't necessarily true in practice (or theory for that matter). Linked lists don't play nice with modern processors and result in frequent cache misses. Unless you're dealing with an insanely large number of elements, there's no need to even consider linked lists. Also, if you're inserting and deleting to arrays you're already using a smart container like Java's ArrayList or C++'s vectors -- both of which allow for amortized O(1) operations. Translation: array insertions and deletions are O(1) most of the time, and O(n) occasionally.
Excellent video! :) Clear and concise. Now, I would really appreciate if you can post a video on Algorithms (Search, Sort), Big O notation, Space complexity.
Wow man...awesome...I am a Java professional and I recently started to watch your video on youtube...you are superb...your teaching style is very good and gives important details point to point with the required practical approach...I have seen your course on your sites too...why don't you come to Udemy so your course is accessible globally conveniently...you really helping people!!...thanks for your efforts and your positive mindset!!!!
Voaleykum assalam, bro. Awesome content. I have summed up before watching it. Because it is absolutely useful content for all javaholics. جزاك الله خيرا
you have gr8 content I went from 0 to advanced in java and spring boot please we need more and more content, like advanced DBA(Postgres or MySQL), End2End Testing, more in deep in DS and Algos, we need your help tnx a lot and please keep going
Awesome content Nelson ❤️ , consider one day to make another video about frontend and backend login with jwt,access token refresh token, session I'd and cookies
Regarding Arrays 9:33, why System.out.println(colors) wouldn't work? Why the toString method is required? Thank you for all the content. I found it super usefull!
Hi! Are you going to create tutoriial java util concurent? How to work with this, What cases are when we should use multithreading Difference between concurrent vs parallel vs async
@ 5:17 - "So for you to retrieve a element from an array is just O(n). Right, so it's really fast." Maybe this was just a mistake you made without realizing it, but retrieving an element from an array is O(1) Great video! Not trying to be mean or anything. Keep up the good work!
5:22 retrieving an element from an array (provided you have the index) is O(1) right? You’ve got the index of the element, so it’s a constant time operation. If you were searching for an item in the array (and you didn’t have the index) itd be O(n)
Hey @Amigos I did not have much time to check your content. But just landed over this video. Maybe it would be good to specify the level of the the course/tutorial is it for beginner, intermediate or advanced?
Hey bro, can you create second part of it with advanced data structures like binary trees, heaps etc
Yes, that was what I was coming for ! It would be great! :))
Yeah that would definitely be beneficial.
^ not entirely, java can handle those data structures i.e BST, AVL Trees
@@marcuspaz4306 u mean we can't implement all ds in java😢 ?
That's gonna be awesome!

Needed this 2 months ago, but I'll take it now haha. Thank you so much! Great tutorial!
Asalamualeykoum bro from Russia! I'm recently a software engineer and I very appreciate your channel.
what's your tech stack?
@@gradientO Spring boot and Laravel
When I started gathering info about data structures you came up with this video, amazing stuff man!

Thank you for your dedication 👏🏿. A lesson on Advanced data structures will be appreciated
Hey Nelson! Good explanation as always, great job! One remark on 5:22. For arrays it's O(1), not O(n) complexity to get specific element by it's place in an array.
I was searching in comments to see if anyone pointed it out.
Your way of teaching is great... 💜
Best refresher on java DSA
So great to watch and easy to follow, thank you!

This is what I was looking for since last week. Thanks, this will be very useful to me.
Thanks Nelson, always appreciate your efforts for the community.
Everytime you upload I'm always excited to watch your courses. Thank you for existing sir and creating Good quality content.

I thought I misheard that lol.

Thank you so much for this course. I really liked learning while reading the java raw and original implementations in IntelliJ.
Excellent video! :) Clear and concise. Now, I would really appreciate if you can post a video on Algorithms (Search, Sort), Big O notation, Space complexity.
i have expected this course for a long. Tks sir!
Awesome content as always!! what plugin are you using to make the indexing and runtime colorful???
Thank you Amigos for your such a good dedication. You are helping a lot
Thank you for constantly uploading high quality content that we just need.

Been looking so long for a good video on Data structure and algorithms in java..
You are a legend, very informative and easily understandable coverage.
Thank you for the quick course, It was very fun learning :)
1:38:40 Note to myself: if you don't override its classes, its comparison is based on object's memory address instead of its content.
Good job , thanks a lot , I watched the full videos and I learned a lot .... thanks once again
Thanks for the work you do. Greetings from Poland

Thanks for your sample explanation
you are great, fantastic channel, but I'd like to see a video about communication between java spring boot with DB, SQL and mongoDB
Assalamualaikum , I am from India. you are amazing .please make a video on threads , multithreading and it's applications.❤️
Voaleykum assalam. Awesome content. جزاك اللهُ خيراً
You are amazing, mate. Keep doing it.
You are amazing!! Thank you so much ❤😊
Love you content
A big thumbs up to you amigo 👍🏻
Good work Amigo I am a self-motivated self-taught Java
Amiiiiigoscode, YES, FINALLY, YESSS thank you !!! data structure, YESSS
Most awaited 🔥 Still need more in DS !!
Great material, thanks a lot
Thanks Nelson, very useful :)
This is such a good tutorial. Thank you sm
Amazing session. thanks brother
Awesome video as always :)
man you're a gem
Thanks! That helped me a lot
thank you very much man this course seems to be very good
Regarding Arrays 9:33, why System.out.println(colors) wouldn't work?
Why the toString method is required?
Thank you for all the content. I found it super usefull!
Hash Functions and HashCode was the best part 🚀
Please create a second part of it with advanced Data structures
Hi! Are you going to create tutoriial java util concurent?
How to work with this, What cases are when we should use multithreading
Difference between concurrent vs parallel vs async
Thank you bro. i like this tuto
@ 5:17 - "So for you to retrieve a element from an array is just O(n). Right, so it's really fast."
Maybe this was just a mistake you made without realizing it, but retrieving an element from an array is O(1)
Great video! Not trying to be mean or anything. Keep up the good work!
Assalamu alaikum bro, Thank you for valuable videos!
Thank you very much bro 🙏🙏👊👊 May Allah bless you
Thank you for this
Can you do a video on socket programming in Java?
Alhamdulillah, the best course on DSA
5:22 retrieving an element from an array (provided you have the index) is O(1) right? You’ve got the index of the element, so it’s a constant time operation. If you were searching for an item in the array (and you didn’t have the index) itd be O(n)
If you have the index of an array then it is O(1) since you go directly to it always in one step.
You are awesome man
Thanks a lot. Awesome Video, great learning.....
Great video 😊 💯 thank you 👍
Love to see another muslim has this much knowledge and share it, Allah bless u brother and thanks for teaching us
super, thank you bro
oya alaikumussalaam oya rohmatollah...
Thanks a lot...Jazakallahu khoir
Please make a series on Java 8 Stream APIs.
hi bro thanks for that great channel and we need videos for soild principle and design pattern in java broooooooooooo
when you cant hate the video , love this mans videos , thanks :)
Hey @Amigos I did not have much time to check your content. But just landed over this video. Maybe it would be good to specify the level of the the course/tutorial is it for beginner, intermediate or advanced?
This guy knows his Java.!
You're epic bro! Your British accent makes it even better.
