Stack Java Tutorial #65

[@alexlorenlee]

If you’re new to programming but want a career in tech, I HIGHLY RECOMMEND applying to one of Springboard’s online coding bootcamps (use code ALEXLEE for $1,000 off): bit.ly/3HX970h

[@Cablur]

The way you teach is so awesome and feels just right. You not only tell people the theoretical terms and how stuff works, but you give us real-life examples, stuff we can literally grab on. This makes learning so much easier and fun. Thank you!

[@tundeolokun7108]

You are literally better than my professors at university. Plates be damned.

[@gabrieldenobrega]

Definitely. I mean, my teacher taught us stacks using static arrays when there's already a class on Java.util that we can use for that! I agree that it may be important for us to visualize how stacks work but the method used on this video is so much simpler and direct. I think that, as programmers, we do not need to reinvent the wheel every time we program.

[@KeilyKapoor-p7m]

I agree, my professor demotivates me to learn programming. But watchng such a good explanation helps me)

[@oshito]

@@gabrieldenobrega In my opinion when you're still learning it's better to know how data structures like stacks are programmed in order to see how it works logically.

[@gabrieldenobrega]

@@oshito Nowadays I see why he wanted to teach us that way, I think I was just frustrated at the time.

[@MafazaSPutra]

Best java tutorial on youtube so far. can't wait to see the GUI tutorial ... hope your channel grows soon! I can only help with subscription, views, thumb, like, and comment ...

[@theFraggedNoobian]

Awesome video, just went through HashMap Stacks and Queues from you and it was so easy to understand with the examples. Coding at the same time with you makes me remember them. Keep it up!

[@abdulazizhaqparast7764]

I would be honest, the way you explain coding with real life examples, it is fabulous.

[@RixCanDoit]

Hey Alex. Yes, the video game visual was fine. I probably would have gone with the cafeteria plates visual, where every time you take a plate the stack moves up so the next plate can be taken, etc. When you put the washed plates back, it pushes down the existing plates. That's how it was explained to us back in the 70's. On another note, sharing 'why' you would care about stacks would be useful. I imagine one might use stacks (FILO) for such things as reversing things you did in your app, like the UNDO menu item we often see in programs. Out of curiosity, what do you use Java for? Program any Windows programs? I'd sure like to see more videos on how to create programs for the Windows OS that NOT console apps, but GUI programs. Don't see many tutorials on that. Everything is mostly teaching in the console. Who wants to run console programs on Windows? Thanks for a wonderful and informative video. Keep up the good work and get this channel to grow!

[@kalyanb2002]

Thanks for sharing great examples for stack implementation in real time (undo).Really helps a lot.

[@preacherluigi]

The pile of dishes is a better way to explain the concept.

[@joondagoon6774]

you explain this in 9mins what professors take a whole lecture ty

[@vladkuprienko7162]

Are they doing it in more depth?

[@joondagoon6774]

@@vladkuprienko7162 I learned this in intermediate programming but the professor had a hard time explaining it so when I took advanced it was confusing

[@michaellabeltran3807]

Hi alex! I'm a computer science student and watched different videos related to java, but you make Java easier for me!

[@TheBsoncarty]

I love your videos! I was doing LeetCode and came across a solution that used Stack, which I had never heard of. Thanks to you I feel like I have a basic understanding now. Thanks dude!

[@notyourangel9]

This is great and the real world visuals really keep things clear

[@vishy]

The video game example for stacking was excellent. You are a fantastic tutor Alex!

[@PrathameshMawlankar]

That's a very clean explanation tutorial for java stacks. The way you explained was neat and easy. Great man.

[@bizcodetech]

Hay Alex, Im your student... You are very Good teacher. Simple and accurate. Im watching all of your videos one by one. And have reached on this. I wish you would teach us android studio, if possible. Thanks.

[@Chris-rw7zh]

The video game visual was incredibly helpful, thank you Alex and I hope you are doing well and happy with your newfound passion :)

[@mohittyagi6694]

congrats m8 for you new office space.. wish you best of luck for your future endeavors

[@NamNguyen-ir7gt]

Thank Alex a lot for helping me learning java in easiest i have ever watched

[@imaanmajal278]

Your videos have saved me for my final and carried me throughout this semester of Java. You explain it way better than my lecturers who just read the slides which are literally just passages from our textbook :/

[@valcmeza]

All of your videos make my day. But I also learn from them. Keep up the good work Alex!

[@2012SnowMan]

Awesome video! The video games is a great analogy for showing the functionality

[@geraldephraim7744]

Excellent video explaining Stacks! Never understood what it meant till after watching this video. Thanks loads!

[@Evilshrimp02]

I just wanted to let you know that even after uploading this video 6 months ago. You are still teaching people. Thank you so much. Yes, the video game stack did help out a lot.

[@ayabonganomvalo8825]

Wooow all of your videos are explained clearly and understandable thanks man🤟

[@slnaisld2121]

the way u explained this was so refreshing

[@andreeadan5595]

The video game visual was really good :) Besides what you presented, I find really useful the "push" method too. Thanks for your videos! They are really clear and helpful!

[@kcconsigo7429]

Best tutorial so far. Keep it up 👍💪

[@Mariam_PinkLotus]

the best explanation ever seen. thank you Alex

[@jeremy1391]

Just discovered your channel recently, awesome videos and explanations. I'm taking data structures at the moment and these have been extremely helpful.

[@chimmypark789]

Thanks a lot for this tutorial. I now finally understood the stacks on Java. Thank you so much!

[@soheylatofighi5165]

Hi Alex, that was very clearly explained as usual. I loved the visualisation.

[@lucassilva742]

holy shit, ty, 06/28/2021 in brazil, and this video makes me very grateful, i couldn't find good explanations about stack anywhere, ty for this video

[@summerche165]

the video game example is really helpful! thanks a lot!

[@mragunathan1627]

another fantastic video, the analogy made it very comprehensible, thanks!

[@kalyanb2002]

Wonderful explanation of the concept using a realistic example (stack of video games). Thanks for making it crisp and powerful..

[@chrisforrest8994]

Your voice sounds so soothing Alex wish my professors sounded like you learning coulda been easy 😅

[@fernandoreyna2990]

The video game visual was perfect for understanding how stacks work.

[@celestial1210]

Great tutorial! Thank you!

[@Applestaffman]

why not use push instead of add ?

[@kainatelahi1322]

You should make course for data algorithm . Because I understood more from you then my teacher.You already have , linkedlist, stack and que.

[@ashuumudunuri3760]

even udemy teachers wouldn't say this great.. your channel must be hyped seriously

[@yolokazinogantsho8111]

Can you do stacks and queues with singly linked list or with doubly linked lists

[@roaa5824]

that was really helpful, thank you a lot

OMG THIS HELPED ME OUT SO MUCH!!!!!!!!!!!!!!!!!!

[@solidninja]

its good to see a gamer teaches stacks java

[@hydrogennetwork]

i think Stack he made is a stack in the JVM's memory. the Stack holds the pools which hold the strings

[@hydrogennetwork]

nevermind Stack extends Vector, i found that out by using CTRL + Shift + T

[@omidmehrabi5620]

it was the greatest tutorial

[@arturus4750]

The video game visualisation was genius in my opininon

[@zhangchi777]

Can someone explain the difference between stacks and ArrayLists? In terms of purpose and functions

[@Emma-wy5yh]

Great video, what program are you using? I like how it auto-gens your main function

[@CrazyGamesMinecraft]

So whats the advatage of this instead of using a linked list?

[@alexlorenlee]

CrazyCode great question! It’s mostly a matter of taste. This uses slightly less memory than a linked list because a linked list has to store info about other nodes. If you’ve got data you want to treat like a stack in a fast way with ways to see the top and pull from the top, feel free to go for a stack. But if you can get it to work with a linked list or anything else, you’re usually better off to go with what you feel comfortable with :)

thank you man !! really great

[@letsdrivewithaz541]

make a video about LinkedList and how to use it. like where can we use it if we are developing any program. everyone talks about node and singly and doubly that's it. Create a program which have all the OOP 4 pilers, Data Structure, and Algorithm. that way we can get a better idea of java. thank you

Can you start a series on building a video simple video game? Even if it's something like a gameboy game, because you could use simple sprites, keypad, simple buttons, alerts, damage, health and all the "simple" things to get moving on more complex games.
