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

[@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.

[@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 ...

[@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.

[@michaellabeltran3807]

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

[@NamNguyen-ir7gt]

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

[@ayabonganomvalo8825]

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

[@PrathameshMawlankar]

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

[@HappyGiftGames]

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.

[@sulbhagirwalkar9917]

best java tutorials ,very well explained

[@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.

[@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 :)

[@chimmypark789]

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

[@mragunathan1627]

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

[@SoteKaGota]

That video game visualization was helpful sir. Loved your videos so far... Hope you will teach springboot...

[@sergiocarbajal4077]

Great tutorial, very helpful.

[@Savageboss52]

Even though I speak very little English, I understood everything, thank you.

[@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

[@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!

[@thushankalana4940]

Thank you so much. You explain cleary and better.❤️🔥😊

[@anujchaturvedi5642]

When do you use the method add() and when do you use push()?

[@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 :)

[@teodorprodanov662]

Very useful video. I understood everything without any problems. Good Luck !

[@vishvesh10]

Bro, you're really good. Love how you keep it very simple. Also congratulations, IK it's a little late probably but still :p

[@proalexv]

Another great video, thank you so much!

[@abdulazizhaqparast7764]

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

[@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!

[@limzisin26]

It's helpful, thank you so much!

[@antons6335]

This is very helpful, thank you

[@aviargas7406]

thank you man !! really great

[@nategalit5407]

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

[@yolokazinogantsho8111]

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

[@arturus4750]

The video game visualisation was genius in my opininon

[@vc9867]

Alex. Thanks for the video. What is the difference between hashmap and stack?

[@sharmfernando3040]

Thank you!!

[@2012SnowMan]

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

[@HelicopterRidesForCommunists]

Thanks my man.

[@omidmehrabi5620]

it was the greatest tutorial

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

[@sebahattinsaral]

this man is amazing

[@vishy]

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

[@pushpagowda7993]

Congratulations 🎉🎊 for new office

[@someguy007]

Oh that was great, thank you. Is there a reason why you didn't use push?

[@naharvlogzchina9641]

Thank you so much,,,

[@baneous18]

Thank you Alex.. you are the best

[@jonathanjordan21]

I really dont understand what is functional difference of ArrayList, Hashset, and Stack??? they functionally works the same except for some feature in the method. I dont really think this makes any difference in a lot situations.

[@luisishere987]

same here, all of this could be achieved with an ArrayList

[@stepbystepcoding4113]

You da man Alex!

[@Applestaffman]

why not use push instead of add ?

[@paia6447]

Stack is similar to an ArrayList

[@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!

[@kalyanb2002]

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

[@geraldephraim7744]

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

[@nevernthirbeni535]

awesome tutorial, you make it really simple.

[@Hogojub]

while(!games.empty()) { System.out.println(games.pop()); } Prints all the games in the real life order

[@summerche165]

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

[@eshah3895]

Thank you Mr Alex, great and easy explanation.

[@yicai7]

Looking forward to ur data structures and algo lesson!

[@kcconsigo7429]

Best tutorial so far. Keep it up 👍💪

[@ghezalshefa7653]

It is a good Example for me to know the details Thanks

[@jx_cob5988]

What exactly is the difference between the add and push methods in java Stack?

[@valcmeza]

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

[@khalidofthesand5920]

"Say your game was... guitar hero" How did you know?

[@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!

[@naharvlogzchina9641]

Can you tall me what kind of Software good for c++programming.

[@gamerneutro3245]

your explanation was wayy so simple, thanks a lot for that

[@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

[@Aayush28jun]

Hey, your explanation to stack is so fun to watch, , I instantly regretted watching Dr Strange yesterday, procrastinating. so boring..!

[@fernandoreyna2990]

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

[@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

[@zhangchi777]

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

[@zacharysong4863]

ur video is so fking fantastic！！！

[@kainatelahi1322]

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

[@soheylatofighi5165]

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

[@chrisforrest8994]

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

[@dd8601]

Video game visualization was super helpful.

[@jeremy1391]

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

[@zubeirayaanle6417]

simple explanation, and easy to understand. thanks man nice office bedroom

[@josue-cm6wu]

I have a question: How can I add a line from the keyboard including spaces into a list.?

[@ayeshamunirhossain8942]

Create a scanner object like Scanner scan = new Scanner (); and then save the input into a variable and add onto the stacks as shown in the video You can also put the scanner in a loop for multiple inputs and adding each input onto a list Hope that helps :)

[@Emma-wy5yh]

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

[@seandempsey4507]

holy i'm drunk and late on my assignment and you made that so ez thanks alex!!! UR A GEM

[@SouravDhali-mc6rc]

thank's brother. love from Bangladesh.

[@MisterWealth]

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.

[@amitmanna2355]

Please make videos on trees, queues, linkedlist, map....

bro teach us much much better than our lecturers

[@karimtoumi3749]

Can you do more videos about interfaces please

[@coreybeaver8504]

what would be the difference between this and an arraylist?
