Hey bro, can you create second part of it with advanced data structures like binary trees, heaps etc

[@MatejDrbohlav01]

Yes, that was what I was coming for ! It would be great! :))

[@OmoruyiOmofonmwan]

Yeah that would definitely be beneficial.

[@marcuspaz4306]

^ not entirely, java can handle those data structures i.e BST, AVL Trees

[@rj27thug78]

@@marcuspaz4306 u mean we can't implement all ds in java😢 ?

[@user-zi4qn9uo9g]

That's gonna be awesome!

[@TheCodejuice]

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!

[@dtPlaythroughs]

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.

[@Hackers16]

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

[@funnycats9738]

Asalamualeykoum bro from Russia! I'm recently a software engineer and I very appreciate your channel.

[@gradientO]

what's your tech stack?

[@funnycats9738]

@@gradientO Spring boot and Laravel

[@Vyse86]

Needed this 2 months ago, but I'll take it now haha. Thank you so much! Great tutorial!

[@kubamusialik5188]

When I started gathering info about data structures you came up with this video, amazing stuff man!

[@rxtechandtrading]

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..

[@mykolahorkov3021]

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.

[@tinasurlan6332]

I was searching in comments to see if anyone pointed it out.

[@sekhafrid3459]

Your way of teaching is great... 💜 Best refresher on java DSA

[@mebaysan]

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.

[@shingiraibondai747]

Thank you for your dedication 👏🏿. A lesson on Advanced data structures will be appreciated

[@nicholascherry5962]

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

[@juliana5355]

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.

[@vpenywise]

So great to watch and easy to follow, thank you!

[@mario_luis_dev]

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)

[@P4Gaming444]

I thought I misheard that lol.

[@raianmr2843]

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.

[@prashantmishra5691]

Thanks Nelson, always appreciate your efforts for the community.

[@rajkhare5949]

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!!!!

Thank you so much for this course. I really liked learning while reading the java raw and original implementations in IntelliJ.

[@Kaox]

This is what I was looking for since last week. Thanks, this will be very useful to me.

[@mohamedriaz7101]

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.

[@daviduntalan]

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.

[@semilife]

You are a legend, very informative and easily understandable coverage.

I really need to watch this from beginning to end.

[@mattsmith6828]

@ 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!
