Abstract Classes vs Interfaces (Java) 

I've learnt more in 9 minutes than my 3 hour long lecture in school. Thank you!

Hands down..... the BEST tutorial on Abstract classes v.s. interfaces!!! The way you delivered concept with wrestlers was a stone cold stunner to me and I NEVER comment on RU-vid videos. please keep doing what you're and thanks for the truth

I cannot describe how beautifully you explained these two very confusing concepts. I won't be confusing either of them ever again.

Love how you went straight to the point 1 minute in. I don't why people always try to take an hour to explain what exactly things are.

I love how you can come from a 4 hour lecture on this without understanding a single thing and watch 10min video and understand everything. Thank you, good sir!

I am paying a stupid amount of money at college for this and yet you did a better job for free, thank you very much!

Using wrestlers for the classes, that is so dope!!! That made this video so much more interesting as well

THIS VIDEO WAS SO GOOD, IF I OWNED A UNIVERSITY, I WOULDA HIRED YOU IN HEARTBEAT

Man you are the hero the world of programming has but does not deserve. Loved that explanation, cleared all my doubts. Thanks a bunch!!

I have been developing in Java since 1996, never saw a better explaination. WELL DONE SIR. BTW, I am going to start using Wrestlers for my presentations from now on. Starting with Crusher, then Mad Dog Vashon, Nick Bockwinkel, etc Long Live Amercian Wrestling Association :-)

Damn man!!! This is by far the best video I have found and it cleared all my doubts. Kane and Stone cold were making bucks but Rock was cooking something.

You deserved my like and save!! In less than 10 minutes i figured it out better than my Professor explained. Well done! :):)

it's been almost 5 years since you uploaded and it is still the best video explaining this topic. thanks mate.

This dude just saved me 3 hours during the night!! Thanks BRO!

thank you so much....my PhD professor wasnt able to explain this to me. bless you man.

I've been reading about these for about 30 pages. Everything just clicked with the contract analogy. Thanks Man!

By far THE BEST explanation and example of abstract and interfaces I've seen!

You're a good teacher. You know what you are talking about. Thanks, buddy.

You're doing the world a disservice by not making more videos. You rock!

this is probably the clearest explanation of interface vs abstract class on youtube. combined with the example and starwars = epic

Really helpful. I've read about both interfaces and abstract classes and it never made complete sense. Really liked the wrestling analogy. Made a lot of sense and I can define what they are now.

Trust this ,I know the whole concepts and i got shocked when i watched this !! you are a genius guy. Best Ever

I have wasted 4 hours reading articles and papers which explain interfaces and abstract classes and still yet to understand. You put those articles and paper to shame by explain this concept in just 10 mins and immediately understood it. Will subscribe.

I love the way you explain it as a contract. Great way to explain this!

This is really one of the most clear explanations I've ever come across. You really made me feel like i'm more intelligent than I think. Thanks.

I haven't finished the video and I know it's 5 years old but thank you so much... It really helped.

Same case here. Watched 3 hour lecture 3 times and didn't get it. Watched 9 mins and it's all clear. Thank you very much! I hope you'll continue making these videos, they're really helpful!

The best explanation of abstract vs interface i could find on youtube. And great example!

i read for about an hour and a half and still couldnt grasp the concept (guess im dumb). this video taught me in nine minutes. you're a champ

OMG! Thank you very much for your video!! Very helpful and never imagined how useful wrestlers can be (as an example) haha

god bless you for using a wrestling example. you spoke to my heart. Great video! thank you for the info!

Absolutely straightforward and easiest to understand these complex concepts

BEST tutorial on the internet!! Thx man, u helped me pass my software exam

Awesome video man. Helped me decide whether to use an Interface or Abstract class in my Android Studio project, after needing to use methods in many of the same activities. Subbed.

You are flipping amazing!!!!!! Great explanation now I can finish this hierarchy class of the animal kingdom for class!!

Dude, You've just brought me out of the confusion. Thanks again, great work!

This is just an amazing and clean tutorial. Never seen anything better, great work.

OMG thank you so much...although I still have further questions on why someone would want to choose an interface over an abstract class this is absolute the best explanation (personally for me) on these concepts. Thanks again!

Watched the first video and Subscribed instantly. Great Explanation.

This is the best video out here for this topic.

Dude I love your voice, its like one of those narrator in 80-90s movies

This is the baddest tutorial I've ever watched!!! BMF award goes to "The Code Hard Truth"!!!

omg this is the best abstract class java i've seen on youtube thankss

Most explanations are confusing because they explain WHAT something is, but not WHEN you would use it, or what it means when you see it being used. It gives the reader more information but no way to slot and fit that information into their brain, and its left up the reader's own intelligence/experience to help connect the dots. Doesn't answer WHY I would want to use something. This video explanation does everything right.

amazing explanation. Much better than other videos. You explained the concept with how to approach & when to approach...really liked it.

Its 2024 and your video makes more sense than my prof ... good job btw🎉

This was a very helpful video in understanding what abstract classes and interfaces are in Java!

Finally I got the difference ! Thank you so much for great explanation !!

The very best video for abstract vs interfaces 🫡

Exactly what I was looking for in an explanation. Keep it up.

Omg this just settled things. You’re the hero that new cs students need T.T

Man i was getting confused by this topic, i never knew when to use one or another in the course challenge man. Thanks!

thank you so much! I was sick yesterday and this helped out a lot.

best explantion on this topic , subbed

Awesome video! so many other videos made this sound so much more complicated then it needed to be. Would love to see more of your videos, you are very good at explaining this stuff.

Such a wholesome intro. You have to make more videos or even a series.

Wow! You’re my savior!!! Very helpful video 🙏

Thank you so much. It is loud and clear!

I have an exam and am pretty sure this will be in it. Think I know it all now, thanks a lot :) Was super confused between these two. I also played a lot of WWE Ultimate Impact and the game from 2003 or so as a kid, Rey Mysterio ftw xd

Thank you, great explanation!!!

You are an AMAZING teacher. Thank you for this!

Reading the book Thinking in Java, great book with great explanations but the author's code examples aren't always that great. Found this video and I instantly understood the difference between the two. Awesome explanation!! Thank you! Just subscribed :)

Very good video man! I wish you had more content in Java. Don't quit telling us The Code Hard Truth

Perfect example of Abstraction. Thank you.

love this, thank you for the real talk and comparisons.

Kane will throw an exception. Tombstone not found. 😂 Excellent explanation by the way.

Very useful and video and comprehensive example!!!.

This video was fire fam, much appreciated.

Thank you for your proper and Way less sophisticated explanation. Really helped a lot bro.

That's a great explaination it's easy to grasp the concept particularly when its demonstrated using examples.

Great explanation on the difference between abstract class and interface. I totally understand it after watching your video, thanks for sharing...

I have two doubts: 1) Why this channel hasn't reached 100k subscribers yet?. 2) What is the use of having a class with no methods at all? And why would anyone instantiate a class with no methods?

Amazing explanation! Thank you for making it super simple to understand.

Thank you so much, I have exam tomorrow and this really helped!

That was great you have nailed these concepts, thanks.

You're the hero we need!

THANK YOU, RIGHT BEFORE MY EXAM!

I learned more in 9 minutes than I did in 2 weeks of my class.

Interfaces can also inherit more than one class opposed to abstract classes (just classes in general)

dude, you made this simple. Thanks alot!

Perfectly explained for those who are Wrestling freak & IT geek.

Best explanation ever!!!

Easy to understand and well explained concepts

Very well explained. Loved it. Hope you would’ve added more about the implementations of these but this will get me started just fine. Subscribed.

Clear explanations and cool simple examples, phat subscribe

You know what you are talking about. Thank for this clarification. It was so confused for me, now I can better explain to someone else.

I've learnt more in 9 minutes than my 3 hour long lecture in school as well. Even that the video was filmed 5 years ago.

10/10 video mang! well done

Such a good example. Great Job.

this is the best explanation ever !

Thanks great explanation got even more interesting with that stone cold and kane's example 🙌

God, i was re-reading this damn chapter in my textbook and it did not make any sense. Thank you!!

Awesome explanation and love the use of wrestlers!!! Haha

Thanks for this vid! Using wwe stuff made it easier to focus.

Good stuff! Made it so easy to understand even with wrestler names 😂🙌

Thank you Mr. Truth

Thank you, I am doing Java opp now in school, and its all online, and I could not grasp this whole concept, I just need some more hands-on practice

Haha bro you nailed it. Very well explained. Thanks!

Thank you so much for the video... Love the explanation

very good explanation bruh - bonus points for the WWF references lol keep it up
