More like 20. His reasoning is not what it actually is, basically he says how he feels about it. Doesnt even explain when you should use A instead of B, that you can use extends and implements simultaneously and why is it useful etc. Like I said "more like 20" but I understand that hes dumbing it down so regulars can understand and that Im procrastinating and probably should be studying for exams lmao
After a year of struggling to understand abstracts and interfaces,I just learned them right now in just 8 minutes. It was really really helpful,you explained it so simply and so good,thanks
in less than 15 minutes this person just taught me abstract classes nad methods and polymorphism, something my college professor couldn't do in a month's worth of lectures. Major thanks from a panicking student in finals season!!
I'm a student in college atm, we just got a major assignment over polymorphism and abstraction, and naturally, we barely covered this. I am super thankful for this video, it has been super helpful in explaining the differences between abstract classes and regular ones and I would not be able to understand abstraction so well without this video!
Dude I sat through a 2 hour lecture on abstract methods and had no idea what my professor was talking about.... amazing what an 8 min video of quality explaining can do.
I couldn't get though how can a 'poop' be a 'void', when it most definitely 'returns' something :) I mean, you definitely see the result, right there! :)
I swear to god I dont understand how abstract works, even after 1 whole semester of learning and trying to implement it. I avoid using it in my project because I'm afraid it will mess it up even more. But after watching this video, I feel like "bruh, it was that simple all this time...??" Thank you man. Wishing you luck on your life journey!
I am a new learner on programming and I am getting stuck on the abstract class concept, this video helped me a lot, I totally understood right now. The example of a dog, poop, made the complicated concept much easier to be got by new learners like me. Thanks, this is a pretty nice tutorial!
Dude you are the only person who could be able to make me understand... the whole class looked at me like an idiot after telling nonsenses about abstract, so called "teaching"!! Super thankful ❤
After or during each of your video can you give us an assignment? Or some sort of activity that we need to answer/code. In that way, we will know the essence of your tutorial.
Hey Alex, you're doing a great job. It would be cool if you could cover how static methods are used in interfaces and abstract classes, and how variables cannot have abstract keyword in them.
Guys, I will have technical interview for programmer job. its about 30 mins from now, need to refresh about OOP paradigm and found this. Thanks Mr. Alex! Wish me luck!
My professor spent an hour and 30 minutes trying to explain abstract classes and still manage to fail to get us to understand it. This is wayyy more clearer.
Holy crap I finally understand this a bit! The problem with most profs, is that they throw all the new terminology and expect us to use it to help us understand what we are learning. This makes so much sense now, thank you!
ALEX!! Thank You for making all these Java videos!! Seriously think that you deserve at least 100K subs for the simple and clear explanations! PLUS it helps that your super handsome and cute
At the beginning of this video, when you said "this may be a bit confusing to you", I swear that words I never knew I had in my vocabulary came to my mind to help me curse, because hell ya, I was confused! At the end, when you clarified the difference between the interface and the abstract class and said "hu, that was a lot!", my brain was already doing the happy dance. Thank you so much!!!
Alex,Thanks a lot,for this clear and simple explanation with cute examples, this is very helpful,and i'd also wish if you could make videos like, kinda creating simple games with java or a demo on some project with java,on application basis of these concepts.. :)
An abstract class helps us organize what that object should do. The abstract method is an idea to organize that object. .... Thank you for explaining this. I just had an interview and I couldn’t put this into words properly.
If have watched some of your previous videos and they were explained too fast for my small brain. This video was laid out nicely. Went slow enough for the the idea to sink in, you kept it simple and clear. Thank you!!
Brother. I love that you're pursuing your dreams and I know you'll do well. I will miss your Java vids. They have saved me. I don't have a good teacher for my college course. 😳Maybe you'll pop up every now and then and throw us Java people some love/bones. Regardless, thank you for being an encouragement and a big help. May you have continued success. 🤠
Dude you're a gooood, i came here looking for the definition of abstract, and ended having the knowledge of implements, interface and the abstract itself, gooood bro
i have BEEN searching for this topic for a long time, i'm 100% sure this is the best video in the internet to understand abstract and interface, Thank you ALOT !
even though this is 3 years after the video, i wanted to say how much i can appreciate your down to earth way of explaining these things. something about it being more like a conversation helps getting the point across way better. keep it up! edit: ahh just saw the "end of java tuts" video. hope the new path is the right one for you! btw nice miata ;)
I’m doing abstract programming right now in a summer course we need to learn c++, python, JavaScript and Haskell in 5 weeks. And I come to ur videos cause it’s soo clear that it translates languages
When you choose the first result off the search screen and it is a really good video and actually teaches you something. Nice job, man. I loved the video!
it took me 40 min to catch up to 3 weeks of lectures so about 6hr of lecture + 3hr of tutorial, if that does not tell you how talented he is in teaching i don't know what will edit he just made me learn abstract classes and interface with poop and bark, so he earned my subscription lol
ngl, i had to repeatedly scrub through the video so I could fully understand your point and not just pretend that I know what you meant. Not saying you explained it poorly, it's just that I'm training my brain to the thought-process. I'm glad you posted these vids on here, you're a god-send! So far, your tut had the right pacing. Keep up the awesome work!
Dude my professor at UCSD explained abstract over a 9 min video and I was like WTH?!~~~ Did not understand at all. You did a fantastic job for explaining to me so i can understand way better. Thank you so much!
Dude, Thank you so much for explaining us in the most layman way as possible. Have always been intimidated to understand or get the right picture of these terms since "years". You just made my java fears fly away by explaining these basics in 10 mins each. Thanks again.!!
I have watched so many videos from so many ppl and you are the only one I understand in all of your tutorials👌 ....Man from now on I'm not gonna listen to my professor and waste my time killing my brain from now on I can say I learned Java from Alex,god bless man!
OOH Alex Lee!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I don't know why I understand only your tutorial with an open heart!! thanks, man for making my life easier. I appreciate you really.
When trying to learn these concepts in school I think the biggest word that through me off was implemented. All the textbooks use it but I didn't understand what it meant. Thankfully you described it very well here and I feel much better. Thanks!
U need to change the title to the difference between the interface and abstract class too. I wanted to know that and I just stumbled on your video by mistake. I now saw the whole video and I also got what I was interested in. The difference between the 2. Great video
this is my 4th time learning java and i was struggling to learn by myself, i mean practising, soo Thanks to u .. u make it clear and soo simple that it reaches my garbage brain. love u man ..plz keep what u r doing cuz we all love to learn from u
i have the worst programming 2 professor but i got extremely better at programming after i found your channel a few months ago. i really appreciate the simple and short videos you make, my final is in a few days ahhh
This man is a fantastic programmer and instructor. He helps by breaking down complex terms and concepts, making them so easy to understand. Definitely worth subscribing, I look forward to more of your videos!
I just love the way you smile man along with teaching these tutorials. This kinda gives me motivation that this this is an easy topic and i can do it. Thanks.

You should literally be teaching programing courses for universities. You explain everything so well!
he wouldnt be able to teach a 10+ week course, he'd have you ready for finals in 3 weeks
love how every start of the video, you would be encouraging beginners like us that are in confusion state, that we will eventually understand it.
That's what got me hooked :P And he was right!
Turned a massive chunk of my textbook into a bitesize lesson. Thanks a million, Alex.

You're an absolutely amazing teacher. Thank you so much for making everything so simple. You communicate very efficiently.
You managed to explain this in 9 minutes what my professor was trying to ramble forever.
You always know *JUST* what I need!
Did you create a program of mind reading?
Everytime something feels off or not all understood after class, I come to your videos and it sums up a 3h in 10 minutes.
Pretty much everything I need to know condensed in

@alex lee
Bro you are genius. You explain it in 10 minutes with simple words. Very understandable!!! You are the king.
I have a Free Response quiz tomorrow, and you just helped me secure my A. Thank you very much, Alex! You have my sub!
Many hours of classes is just within 9 mins....you explained clearly just like a friend explaining everything 10 mins before exam.
Broskiii this was the best 9 minutes of my life, I love you thank you so much. LIFE SAVER
so in an abstract class we can have methods that are not abstract but in an interface we cant. makes perfect intuitive sense :)
This was extremely helpful. You are very talented at teaching and keeping it concise. Thank you!
You should teach in university. These are the best Java Videos i have seen! Thank you for saving my butt!!
Hey Alex, you're doing a great job. It would be cool if you could cover how static methods are used in interfaces and abstract classes, and how variables cannot have abstract keyword in them.
Guys, I will have technical interview for programmer job.
its about 30 mins from now, need to refresh about OOP paradigm and found this.
Thanks Mr. Alex!
Wish me luck!
You may or may not have just saved me from failing my exam
howd u do
I hope u did well, I got my exams this week...help!
My professor spent an hour and 30 minutes trying to explain abstract classes and still manage to fail to get us to understand it. This is wayyy more clearer.
Nice work brother. Other people made stupid tables and listed the differences. You explained all in 9 minutes. Respect
Can you do a video where you explain all of your shortcuts? It would really help me save more time
Holy crap I finally understand this a bit! The problem with most profs, is that they throw all the new terminology and expect us to use it to help us understand what we are learning. This makes so much sense now, thank you!
ALEX!! Thank You for making all these Java videos!! Seriously think that you deserve at least 100K subs for the simple and clear explanations! PLUS it helps that your super handsome and cute
I think you deserve to get gold medal 🥇 if there is such a thing for Java instructors. I wish all the best for you!
Making and implementation of a GUI currently what I'm struggling with right now also do you use the java library site religiously or not that often?
Very few can explain these very basic core concept of Oops with such clarity. Your basics are so so clear. Thanks
"Every dog poop a little differently ", I laughed for almost 3 minutes lol
At the beginning of this video, when you said "this may be a bit confusing to you", I swear that words I never knew I had in my vocabulary came to my mind to help me curse, because hell ya, I was confused!

This is the simplest yet best explanation on abstract classes and methods i have ever encountered. Kudos Alex.
Could you do some interesting projects with java
maybe
An abstract class helps us organize what that object should do. The abstract method is an idea to organize that object. ....
Thank you for explaining this. I just had an interview and I couldn’t put this into words properly.
Is this the only difference between abstract and interface .. or something yet to add
You can implement multiple interfaces but you can only extend one class regardless of whether it is abstract or not.
If have watched some of your previous videos and they were explained too fast for my small brain. This video was laid out nicely. Went slow enough for the the idea to sink in, you kept it simple and clear. Thank you!!
Can you make a tutorial about java GUI using javaFX ?

Thanks for actually stating the difference! So many people will give characteristics without really defining what they're talking about.
I learned more in this class on Abstract than my JAVA class at a California University. Alex was very clear about how it works. Saved me!
even though this is 3 years after the video, i wanted to say how much i can appreciate your down to earth way of explaining these things. something about it being more like a conversation helps getting the point across way better. keep it up!
