In 8 minutes I understood what I could not understand with my teacher in 2 hours. Thank you so much

[@YoursTruelyMe2]

Right! People like him I would be happy to take a loan out and pay for this amazing teaching.

[@MariaBure]

Same here :D!

[@jaredchong4070]

School is not really teaching people to be smart.Its to create industrial age employees. They taught people in a one way learning style and dislikes creative diverse ways of learning.

[@ibuucoksiregar9024]

So dammn true.. i read several tutorial on internet about this inheritance stuff..but they cant help me to understand clearly..but it only takes minutes to understand when i watch this

[@gloverelaxis]

yeah a lot of teachers in CS are fucking useless. Dan actually understands teaching well

[@sorosw2980]

Y'all this guy is teaching with such enthusiasm, he gets my respect. 💯 Keep up the good work!

[@halefspencer2725]

This is why I love youtube. Understood in a couple of minutes what a I couldn't understand on a 3h long lecture. Thanks a lot!!!!!

[@johnwt7333]

What does it tell you about your intellectual skills?

[@EmporerAxel]

Thanks so much for this, this was one of those concepts where I understood the theory but couldn't understand why I would use it or why it was so important. Your enthusiasm is infectious :)

[@saif0316]

This is my first lecture to click on and I have to say, this guy is amazing. The level of enthusiasm he has is incredibly contagious.

[@Chillaxzino]

This is my best tutorial on Polymorphism

[@algoprism2833]

Best code teacher I could ever find. I am so happy to be here.

[@magik0630]

congrats on your role in casa de papel, you did a great job

[@nataliedelgado3990]

Hahaha I thought the same!

[@drakulea4301]

finally an insightful understanding of polym... I feel as many people don't grasp the essence of polymorphism and they just see that polymorphism is child classes overiding methods from parents or interfaces, but in reality they are truly missing the point .. which is to create more flexible and reusable code that can accommodate various types of objects. so the power is the fact that you can lets say have a method pet(Animal a) in any other class and any object of a type that inhertis from Animal would be propper argument for that method.

[@thekoolcatsesh1932]

It's funny you say that. I'm not "required" to watch your video, but it is a requirement for my studies to understand object oriented programming in abstraction, inheritance, polymorphism, and encapsulation; but you teach very well, and I understand it. I'm glad you're doing what you're doing.

[@k1awdttt]

Just want to let you know that your explanation is very good with great and clear examples. I'd love to see more abstract concepts being explained by you too, like using abstract class in concrete class in OOP designs, invariant and variant, observer vs observable, event-driven design, etc.

[@Daniel20030]

"I'll edit that out", always :)

[@michalbotor]

it's like a running joke among creators these days. ;p

[@regardspratik]

This guy's enthusiasm is addictive.

[@manuelalfonzoml]

This guy teaches me more than a university teacher, and does it with such a goddamn passion. Thanks man!!

[@ArmyLyra]

How i wish you are my teacher. I actually understand you under 8 min and i cannot under my lecturer for the past few months.

[@salmagamal5676]

YOUR ENERGY IS CONTAGIOUS AND I LOVE IT. thank you!

[@poloska9471]

Great video! It was an easy enough beginning to be understandable by pretty much anyone with a programming-afluent mind and towards the end difficult enough to explain polymorphism in actual practice such that a person who doesn't know what polymorphism is, can pick up this principle and run with it to any heights they want to take it - whether that be just one extension of a class or many and usage in complex scenarios with all 3 principles of OOP playing a role.

[@GermaphobeMusic]

Previous episode: 12,000 views This episode: 100,000 views Makes sense.

[@littlecurrybread]

omg three textbooks and like five videos and i couldn't understand polymorphism but this video FINALLY helped me understand it, thank you!!!

[@darkclove7365]

Best video that explain polymorphism. Easy example to follow on the whiteboard, easier to follow this than someone trying to explain it in their way on the computer. Me, I knew what it was before going on this video, but had a hard time explaining it well in an easy way, even though it isn't a hard topic in itself. Maybe I'm just dumb. Much love!

[@emex4gman2]

Wow, thanks for this, 6yrs down and this is still valid

[@fotoh1589]

You give me hope that this world is still livable

[@jspesh]

You are by far the best code teacher!

[@screwyshow]

Extremely happy I came across this video.

[@princeofxane]

After watching so many videos finally, he explains it beautifully. Thanks.

[@anirudhgupta169]

The quality of the content and the detail in which Daniel goes is very refreshing. I love the way he explains things and uses decent quality example. He is clearly quite passionate about programming and tech in general. But is it just me or is the content on this channel all over the place with very little to absolutely NO organisation and sequence to the content? It is impossible to follow a train of thought based on the serial numbers of the videos and/or the playlists. No links to earlier content that Daniel keeps referring to. For instance the Particle example, he is clearly using a library, but where, in which video is he doing the development environment setup so we can also follow his explanation while trying to simulate what ever he is explaining. That leaves me a little frustrated.

[@the_calibrator]

Effeciently and effectively explained - extra credit for the passion. You've earned a new sub

[@cmarc2156]

This is literally the best video on polymorphism in java

[@systemloc]

Really great. This video is short, efficient, and very effectively communicates the concept. You got another subscriber.

[@benjaminrogers9848]

I know I'm a bit late, hope you see this but this was really fun to watch and helped me make a lot of connections of content I knew but couldn't put together until you burst onto the screen with an enthusiasm that students dream of, thankyou!

[@unicorneyelasers]

I absolutely love your enthusiasm! Very enjoyable to watch

[@saadiyafourie]

YES SIR! You're amazing, appreciate the enthusiastic, relatable way you lay it down. I am so much more confident about Java.

[@ahmedtabti2264]

:) very good exempl its very helpful for inderstanding polymorphism ,thanks very mutch ,

[@michalbotor]

really cool concept is this polymorphism. and your explanation of this and inheritance was so exceptional. now i finally understand them thoroughly.

[@ianr8060]

You explained polymorphism way better in 8 minutes than my Java teacher did in 2 hours.

[@eddie9559]

third polymorphism video, finally got it. Thanks!

[@primoashbee]

El Professor whats up. Excited for season 4!

[@masouddayaghi5923]

I wish I could be happy like you

[@timsandman]

So Simple! Wow After a year and a half I got it! Dan's videos are really great to watch. I am learning Java but they translate to any language at a certain level.

[@louiscouture9139]

Wow thanks. You made me understand what polymorphism is which my teacher couldn’t

[@IRWBRW964]

Videos 8 and 9 seem to be set as private in this Nature of Code playlist.

[@kossyoto1]

Man, thank you so much for the great tutorial, I love the way you explain as well as the energy you put into you videos, learning from you a lot! Keep rocking!

[@aneiger8706]

Absolutely the best video about polymorphism out there!

[@ketchart2789]

Thank you very much!! I really like your teaching style. You're like a ray of sunshine!

[@urunclesam1659]

HOLY MARY MOTHER OF CHRIST THANK YOUUUU

[@jafethgarcia4819]

Love the energy you put while teaching, makes it much more interesting! Thank you!!

[@TheCodingTrain]

Thank you!

[@cholasimmons]

I wish you taught me programming when I first developed the interest

[@laubes7481]

This guy is so incredibly passionete, so good!

[@tsubarider13]

So basically polymorphism is inheritance? What's the difference?

[@SourabhBhat]

Using the methods from parent class (without overriding) is inheritance. Implementing/overriding a method in multiple classes is polymorphism.

[@CStove]

I love his excitement

[@wizardcodes5341]

Amazing Job man Coherent communication .. salute

[@weltraumimport]

congrats to 200k subscribers!

[@Ali-mi9up]

Btw in the video are you assuming that the methods are already overriding similarly named methods from the parent class. Because if you're calling methods that are only in the child class on their own, that'd lead to an error

[@user-ec1py5nh8d]

Daniel, you are very very good at what you do. a life of meaning and purpose. I envy you Sir!

[@sertcow]

Wow I wish this guy knew everything in the world so he could teach me.

[@muhammadovaissiddiqui3895]

Finally understand polymorphism..!! 😍😍👏👏 Thank u sooo much sir for making this video.. ♥️

[@ahmedbugti3152]

First time saw your video. Couldn't do much just subscribed.. Awesome.

[@AnthonyJones_Linuxson]

Thank you so much for this video, I finally understand what Polymorphism means now!

[@sarvinasalohidinova4881]

It is the best video on this topic

[@ThePersepolis32]

Thanks you, it was very helpful to know what is Polymorphism

[@Zagredful]

Respect to you, understood everything.

[@alda-ir]

Wow, awesome explanation mate!

[@Gregasaurus]

great teaching style. dynamic, fun and clear af.

[@yeukaimutemachimwe9005]

so interesting good teaching skill halalalaa

[@jurjensleebos5058]

I so wish you where my teacher right now.

[@RodrigoNishino]

Very Nice ... I'm THIS CLOSE to dub you in Brazilian Portuguese

[@Zakariya0101]

Thanks a lot, that was easy to follow and understand from the first minute.

[@milindshinde5896]

Amazing explanation

[@karmaindustrie]

can i write for (Dog d : Kingdom) { d.sleep() } ? in order to only loop through the dogs.

[@swastikbhat5874]

I think this would work but, it would only put the dog to sleep not other animals.

[@WaterDragonFist]

Must you first declare the dog class before declaring other dog objects of different classes? Or it doesn't matter? The objects would be created no matter what?

[@joashkick4178]

Dude ...I quess your students won't afford to miss any of your class ,Profesori

[@ronglass5968]

Thanks for the vid! This was very helpful. Great jumping off point for Polymorphism! (btw, watched the vids on inheritance first; best way to go).

[@lazymacs2823]

What are the other situations that polymorphism is useful?

[@supernovic99]

This video was amazing!!! Thank you so much!!!

[@maxim25o2]

And what if dog.eat(), cat.sleep(), If I loop thru vector, then I want only dog to eat, and cat do nothing. Do cat will be also not called from vector? Or it will be, but function of eat() for cat will not exist, and class cat will return just 0, from base class?

[@Supwisebs]

Love you Dan.

[@SmartProgramming]

awesome, just awesome, thanks a ton for the tutorial 👌👌👌👌👍🙂🙂

[@uday8112]

Man you are incredible....... how do you do this!?!? your videos made my day 💖💖

[@sameeruj]

Simply Awesome!

[@debajyotibiswas9839]

You are an awesome teacher! Thank you!

[@BoutinMathieu]

Very nice job, thank you so much!!

[@kustomweb]

1000 new subscribers every day. Great channel

[@gplus46]

Do the object/animals know they are distinct because of their identity name?

[@holthuizenoemoet591]

simply amazing , your explications are fantastic !

[@ratabahmehras4847]

Wow!! You simply save my day.. ♥

[@titofrezer6201]

What an explanation !!!! sir thank you very much

[@ZiadddTV]

best explanation ever , thanks

[@Eltopshottah]

I love this guy

[@cynthiaayers7696]

Einstein's theory. The manifestation of a polymorphic form. From Ram to R.O.M. A coding system of thermodynamics, in a unified theory of the forms. Meaning: O. Energy, to a harmonically balanced regenerative wave form. The cause and effect of these forms. To self manifest, In a chain reaction. Example the demon core of Trinity's. Or music. Sound waves of scalability/size. 1/1/2023. AKA spark in the dark.

[@nicksonmlelwa6583]

Wow it's so nice sir!!!

[@sravanisiva8414]

Extremely fantastic 😀 thank you very much 😃

[@wing3789]

beautifully explained. Thank you!

Thank you so much. You really helped me understand it.

[@imyasharya]

1:35 It reminds me of the particle systems I used in Blender to create sprinkles for my donuts.

[@ready2ree100]

guys please help me i didn't understand the coding part which language he was explaining

[@juniorroberts13]

Awesome. You're a great teacher. :)
