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

@MatejDrbohlav01 2 года назад

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

@OmoruyiOmofonmwan 2 года назад

Yeah that would definitely be beneficial.

@marcuspaz4306 Год назад

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

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 2 года назад

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.

@Sauce-ke 2 года назад

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

@Vyse86 2 года назад

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

@rxtechandtrading 2 года назад

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..

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.

@mario_luis_dev 2 года назад

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 Год назад

I thought I misheard that lol.

@raianmr2843 Год назад

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.

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

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.
