Me: *Reads about 34 pages about Classes in a textbook, eyes glaze over* Me: *Watches this 7 minutes video, immediately understands everything* THANK YOU!

[@tompol5433]

[@partytimeninja3139]

Me: Pays £9k per year so a lecture can expertly tell me how to do it, eyes glaze over Me: Watches this 7 minutes video, immediately understands everything

[@magicvibrations5180]

My professor always tells us when we design a Class to go through the following steps: 1: What attributes do we need? 2: Write a constructor 3: Decide whether or not to have getters and setters 4: Write your methods. Also, even if you don't include getters/setters remember to explain why in the documentation to make it more readable.

[@jessegonzalez8904]

No joke, Alex pat yourself on the back man 👏🏽 You truly changing people futures with the knowledge you share. Respect ✊🏽 Here to say thank you for helping me for this semester. Made a 100 on my midterm and a 96 on my final 💯🔥🔥🔥. Thank You!!!!! god bless 😇

I can't even believe how easy you make this to learn. When my programming classes started online due to covid I thought id never make it with the lack instruction I had, and then I found you.

[@trollface1994]

...and now you're married and have his babies. great stuff !

[@seanthomason3851]

I feel that I have learned more watching 30 minutes watching your videos than I have in a semester in college. Thank you so much!

[@alexiosflash]

You are a lifesaver! I’ve spent the last week trying to learn how to do a driver class and three minutes into your video you do it! You’re amazing!

[@jasonbui95]

Hey man, I really appreciate you breaking things down to the First Principle. It makes the tutorial really easy to understand without getting panicked about all the other advanced keywords and usages!

[@riccardo7585]

You are saving my school year, thanks a lot

[@pitchrocker12345]

Dude,its just been couple of days since i found your work and its sooo good man!! you're like one of the best things I found in KZbin this year ☕☕☕ :)

[@marielwillbanks7320]

Thank you! This video was so helpful in understanding classes and methods. I started a programming class a few weeks ago and until watching your video I still didn't know what the first couple of lines of code I was typing really meant. All I knew was the program didn't run without them. I feel much better about this now.

[@SpooxyCowboy1911]

dude you just helped me out SOOOO MUCH. i was having trouble understanding it the way my professor explained it but this made it crystal clear. new subscriber

[@justinschmidt9652]

You’ve gotta be one of the best teachers on KZbin. Thank you so much for sharing all this

[@benheim5055]

Like everyone else here, I struggled with this concept while reading multiple online resources. This video presents the subject matter succinctly. I learned more in these 7 minutes than I did in the past 7 days. Thank you.

[@izikki11499]

Dude, you are amazing. You make programming so damn easy to understand and make me understand it waaaaay better than any of my professors, making me a better programmer because of you. Thank you for making these videos dude you are awesome keep it up.

[@0xjocxyen2]

For me as a beginner, the most difficult thing to understand is java object, class and instance. You explain this clearly. Thank you.💓

[@dee23gaming]

Omg 😀 , you are the only one who can properly explain how to use classes to communicate information between eachother, it actually so easy. I'm coding this on my phone using Code Studio IDE. I'm usually an Android coder, so this won't always work the same, but man you taught me some core Java basics. Thanks, you are by far the best Java teacher out there 👍

[@zb2747]

Simple and to the point, covering the basics and core concept. Thank you.

[@mohammadyousef8447]

Alex, your classes are still useful and clear in concept. Thank you for sharing your knowledge and generosity.

[@Bawdog4]

I took java my freshmen year of college and this is a great refresher

[@ashevilleislove]

You are amazing. The way you teach is perfect for my brain! Much better than my current class in school.

[@namratapai4650]

Great Tutorial Alex. I used to be so confused. This surely helped me understand. Thanks a lot for teaching so well.. :)

[@KarinaGarcia-tk5re]

ALEX TE AMO! thanks to you I learn more than from my whole degree! LOVE your videos!

[@SwinkMediaHouse]

Reallly helped me to understand classes more… great vid!

[@sparrowXXIII]

Thank you for sharing your knowledge, Alex. Much appreciated.

[@dronef0415]

My AP Computer Science teacher started teaching classes last week and he skipped the explanation and started doing a project and I was so confused on what he was doing. This video cleared my confusion, thank you!

[@tcinosomseb5220]

Wow! finally something better than my professor and his online classes I didn't get anything of. I was going to fail this semester if it wasn't for you. thanks a lot bro, the world needs you.

[@user-zj1nw8hw1z]

thank you so much I was having really hard time to understand , you made it so much easier .

[@osahenagharuosagie2799]

Woow. You are an inspiration to many people including myself. Thank you so much and God bless.

[@xXStevenHerbavoreXx]

Took 4 minutes of your video for me to actually understand classes and objects and how they work, im 6 weeks into my semester learning java and trying to find information online for an explanation and non of it seems to actually help. Im subscribing because i believe thisninformation will actually be beneficial to me and my progress.

[@lusciouslocks151]

Hello Alex, thank you for all your videos, they're truly all helpful. Can you please show us a video of understanding and analyzing time complexity?

[@Michelle-ze9sf]

Thank you so much i love you, you just saved me for my java class

[@puneetshakya3001]

Love your way of explaining concepts

[@crunchyeater]

Great video. Simple and succinct!

[@joshuadouglas8483]

You have single-handed kept me in my class without you great explanations I would have dropped out.

[@maryp1131]

great tutorial! You are saving my degree!

[@fateme5705]

Thanks for teaching. I learned easily 😌

[@teenytinytoons]

No doubt the best explanation ever and I’ve watched a shit ton of videos.

[@LanceLiebenberg]

Thanks so much bro. This really helped me understand classes and objects better.👍

[@myawsomevideos456]

Extremely helpful! Thank you!

[@rubinconineski526]

It is very easy. Thank you.

[@Cablur]

You just never fail to explain stuff super easy 👍

[@yoni1991]

Thank you for your advised! love it 7 point.

[@saintz2k7]

Hi Alex! you are a hero among men and are the reason a lot of people will become a software developer in the future. Pretty amazing to know you are directly responsible for the next potential facebook or instagram! I don't suppose you would be able to do a lesson on understanding JVM, JRE and JDK and all the other background mechanisms of Java? I have a hard time understanding it all and you explain things perfectly.

[@gabrielerosadini9136]

What a good job u did with this video

[@joethompson8147]

Excellent introduction to classes and objects Alex

[@mehdi.sajadi]

[@madhushreekulkarni9866]

Thankyou so much! its helping alotttttt

[@sooso1231WW]

Im so sad I just found your channel, your vedios would’ve helped me ALOT with the first couple java courses and I would’ve got A+ easily

[@nllentfaw]

So so useful. Thank you!

[@thanossym2281]

Thank you so much for your video! :)

[@santiagoespinosa1229]

In 15 minutes this man gave me a great visualization of what are classes and methods and how they work, meanwhile 3 hours reading 2 book chapters left me more confused than when I started. I love u man I'm so happy I found your channel

[@jacobyarmani1906]

😂 for real it’s was easy but the books makes it complicated

[@taur6115]

I bought a Udemy course before I discovered your channel. I think your thought process is much better than the instructor's in the Ud course.

[@Arejayy8]

[@highmountdigital]

Video is well done and super helpful 👊

[@CosmonautCoding]

[@Maltebyte2]

Good that you exist!! So do methods tell objects what they can do like walk, jump, follow, make sound etc?

[@jakewiest389]

This video helped me so much on an assignment that I was going nowhere on... Too bad my professor didn't link your video!

[@yeliza2350]

8 january thnks Alex

[@lightningllama]

One of the most important points to note for beginners is that the main function declaration is *within a class*. That's unlike any other programming language

[@zuwert9743]

thanks

[@tibey9171]

better than my professor!

[@undertaker343]

I have learned alot of stuff online this couple weeks ;) i did my own bank atm programm :D but what i am struggling now is expirience. like when i get a problem i know the theory code but dont know how to start or i end up doing over - compicated programs and long ones

[@mmusomodungwa6475]

This gonna help my PAT

[@shredderspencer1122]

Great pedagogy! You could change the world if you taught us more subjects.
