Amazing. Truly, I love java. Interfaces alone sell me on the language sooooo much. So damn powerful. Your videos help a lot man! 2 semesters left till I graduate from cal state east bay! Been grinding my java and python and using your leetcode videos to really help. Keep it all up, your content is very real and useful.

[@KeepOnCoding]

Keep it up!

I been learning Java for the past year and have watched A LOT of KZbin tutorials on it. Yours are easily the best out there, straight to the point and easy to understand.

[@phoenix78240]

Out of all the videos I’ve been looking at on explaining interface your video is by far the easiest to understand. Thank you for that.

[@doctorpoverty9553]

The most in-depth video. At first, it seemed complicated. But after watching a few times, I have realized that this video actually covers more than 10 credit hours worth of college classes in one 15-minute video. Excellent job man. You are a life saver

[@BN-cr3el]

The way you explain it is... I can’t even describe but I learn very quickly and I learn a lot in few short minutes. In class, we spent 3 hours learning about interfaces and I was still confused. Thank you 😊

[@venkateshnambi1576]

I was struggling to learn some concept's and i regret that i am so late to watch this video. Fundamentals cleared. Thanx.

[@Gohel95]

this was super.... Please keep making such good content it helps too much ..... and your way of explaining is just awesome first some theory and then code.

[@i.j.5172]

this was genuinely the BEST video I have seen on interfaces. Complete explanation.. thankyou!

[@JATJAT330]

Literally the first minute of this video explained better what an interface does than the entire book I have to study from. I just didn't understand the point of them. THANK YOU!!!

[@matthew11092]

Learned a lot from your videos, your explanations make sense and are straight to the point

[@rubasham8241]

your videos are like a survival kit, whenever i feel like a topic is too heavy because my professor didn't explain it well, a video of yours pops up and it never fails to give me back hope and make me understand! can't thank you enough!

[@CodeRay]

Awesome video man! Wish I knew this when I was in AP comp sci

[@leonardolima3936]

Great explanation! You speak english clearly, It was easy to understand

[@KD-vg2yn]

What a great tutorial. Thank you man. Also, I think it's so funny, on productive channels like this, the comment sections tend to be so nice and not toxic. But in all other comment sections on KZbin they are all toxic. I think it shows the kind the of people you attract when you are doing something great.

[@ParalyticAngel]

Even me whos English isn't that well do understand it by far better than guys in my language are explaining it, by your way of explaining stuff. You are really calm and on point with your style of explaining it. Respect and thanks.^^

[@michaelantoni8323]

I'm learning Java now and the way you explain it really amaze me. Thanks a lot your a big help. new subscriber here.

[@PunjabiKush]

Here during my Final, I just finished part 1 on abstract using comparable. was uncertain how interfaces work. part 3 is generics and I'm pretty good at it. Thanks dog you helped me pass this probably with an A :)

[@vadrudnev]

Thanks! I had troubles understanding how to use interfaces. This video saved me a lot of time.

[@mr.RAND5584]

You speak so crystal clear. Thanks 😊

[@kaifahsan8459]

Great video. Like how you explained a lot of key aspects of interfaces with clarity.

[@kiransingh8239]

HI Sam , too good to see u explaining the clear concept

[@guy8923]

When I need to revisit something your videos are perfect

[@socaljusticewarrior558]

This channel is tight. Because of you and Coding with John, I've basically become a PHD in computer science.

This is great quality material\, my guy. You definitely earned my sub.

[@ammarabdallah378]

hope to see more videos man you are such a legend

[@williaminfiesto2529]

Thanks, this is a very clear explanation and it helped me understand interfaces a lot more!

[@martinrugadya4067]

This is super helpful, precise and clear

[@khushiimalik]

Very well structured and easy to follow. I was having trouble with interfaces. Thanks!

[@marouaneltaifi2926]

great work man loved the video keep it up !

[@sethupathys641]

Thank you. Can't believe how much youtube teaches me

[@KRaJWanders]

One of the best explanation of interfaces. Worth every second ❤❤ Thanks @keepOnCoding

[@muhammudamine7376]

Best Video at explaining Interfaces, Thanks

[@christo4520]

Dude you have a good content style

[@uralslife]

That's awesome job, man. I'm declaring that from Russia, we don't have such a clear interface explanation even in paid cources

[@ahmedababneh7089]

Please can you make a video that talk about the first step should I take to become a java developer, what should I learn and how many month it will take. Sorry for my English.

[@kamogelomafuna8485]

Wow I never understood interface until I saw this tutorial and might i say it really came handy ass am writing a text this coming week

[@maddy3656]

Thank you! I adore your videos. 🥰

[@fastcomputer5927]

Nice keyboard sound :)

[@obiudeze809]

@keepOnCoding Great Vid! It seems the use of inheritance in sub-classes and the use of interface implementation in classes are kind of similar. Are there any situations where you would use one or the other?

[@jamaka_me_code796]

Wishing you had a Spring Boot tutorial 😅 appreciate your content for sure

[@matttwist9480]

Awesome video, thanks for making this.

[@DespinaDimitriadou]

Great video! Can you do one for abstract classes as well?

[@Gohel95]

can you please make the next video on the collection ... because I have seen many tutorials but I think only you can clear concepts of collection.

[@francescocassini7267]

Great video! It was very clear!

[@dane-c7g]

Great video, much appreciated!

[@swapnaligouda4600]

you are so cool, man! please make videos on the complete java collection framework and data structures and algorithms.

[@PIRAKAS666]

Very nice. Appreciate the effort. Also so much better than that over the surface trash Lee is uploading.

[@puppyspit8725]

That was very receivable. Thanks for the info

Thank you for this very useful tutorial about interfaces, I'm getting started with it and now default methods in interfaces classes are clear to me.

[@georgesavvatis1937]

This was very helpful... thank you!

[@Duderantula]

Thank you, great explanation.

[@rezafadillah5129]

Thank you broo, your explanation very detail

[@samueletamburrini9420]

Man really awesome, but im struggling in 5:14 when you talking about creating variables istantiating interfaces. When you reference the interface istantiated to another object (in this case ob=byTwos) you are modifying also the other class (byTwos) or just the interface istantiated? Dont know if I made myself clear.

[@escrimo23]

Great video! This is a really side question, but what are your thoughts on developing mobile apps using Flutter(Dart) or Android Studio (Java)

[@sammeester3514]

Great video, thanks!

[@maxd7228]

Have you thought about making a Java course? Excellent explanation.

[@morghayn]

Great tutorial!

[@Nxtfbrdf]

Good teaching skills ❤

[@facundomartinez615]

Great explanation!!

[@msh104utube]

When would one choose to use Interfaces over. Abstract classes, and vice versa?

[@aureliuse3469]

I think abstract class is use, if you want to make that class contain abstract method and method with implementation, but interface use only to share abstract method without implementation to other class only and share final static variable. Beside that the different is in a class we can extend 1 abstract class only, but otherwise in a class we can implement many interface. So if you want to make 2 superclass with 1 subclass use interface, and if you want to make 1superclass and 2 subclass use abstract class, i think that is the analogy of the hierarchy. CMIIW iam also learning java interface tq

[@yasminenejjar6351]

Thank youuu so much !

[@CarlosVasquez1]

OK. but it seems like your conflating class and interface. In the portion (around 3:25) where you are explaining implementing interfaces and extending classes you are saying "implement class" and "extend class". Is this the correct wording? Is there a difference between an interface and a class? More importantly, are there different rules when implementing an interface vs implementing a class? Can be a bit confusing if not used to the terminology and rules yet. tx, -C

very good, thank you.

[@zhihaohuang273]

Could you explain how the method "public void mousePressed(MouseEvent e)" was written? Is there a way to add functionalities to a method in an interface? Thank you!

[@rosameliacarioni1022]

THANKS A LOT !

[@pzmt8051]

[@shx717]

How about interfaces in Java 9 and how are they different from abstract classes in Java 9 since you can define functions too.

[@medhaniegebru2120]

AMAZING!

[@saxontse]

thank you for video first, but you just mention about how to use interface. I am confusing of why and when to use interface, it is so hard to find useful material that can describe deeply on that

[@a.p5332]

thank you soooo much!!!!

[@stevenmatthewrevillas7794]

why didn't you used override in 4:29

[@jacobgorinevski1544]

Thank you

[@sachinsharma1230]

Everytime when i see this "default" method i fell like what is the "suger coating" done on it. I never found any answer on it. You know what i men, the default access / non-access modifiers
