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

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!
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.^^
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 :)
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 RUclips they are all toxic. I think it shows the kind the of people you attract when you are doing something great.
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.
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
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.
@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?
weirdly i tried to go along the video and do the same in Intelj Idea i made sure everything was the same even names of the class and interfaces, but i got errors in places where there werent in the video , like overrriding printStuff method , it highlights the parameters like there's a mistake , what could be the issue?
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
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
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!
I like the idea of "real-world examples". In my internship things were much easier to accomplish because the goals were clear. College doesn't do that. Not in my experience.

did you finish? did you persist? did you find a job??@@tannerbarcelos6880
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.
I been learning Java for the past year and have watched A LOT of RUclips tutorials on it. Yours are easily the best out there, straight to the point and easy to understand.
I was struggling to learn some concept's and i regret that i am so late to watch this video. Fundamentals cleared. Thanx.

Great explanation! You speak english clearly, It was easy to understand
This channel is tight. Because of you and Coding with John, I've basically become a PHD in computer science.
When I need to revisit something your videos are perfect
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!
Awesome video man! Wish I knew this when I was in AP comp sci
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.^^
You speak so crystal clear. Thanks 😊
HI Sam , too good to see u explaining the clear concept
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 :)
This is great quality material\, my guy. You definitely earned my sub.
One of the best explanation of interfaces. Worth every second ❤❤ Thanks @keepOnCoding
Thanks! I had troubles understanding how to use interfaces. This video saved me a lot of time.
Best Video at explaining Interfaces, Thanks
I'm learning Java now and the way you explain it really amaze me. Thanks a lot your a big help. new subscriber here.
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 RUclips they are all toxic. I think it shows the kind the of people you attract when you are doing something great.
hope to see more videos man you are such a legend
Great video. Like how you explained a lot of key aspects of interfaces with clarity.
6:20 - Polymorphism in action - ability to execute different behavior, for different objects types, which are determined at the runtime.
Thank you. Can't believe how much youtube teaches me
Dude you have a good content style
Very well structured and easy to follow. I was having trouble with interfaces. Thanks!
Thanks, this is a very clear explanation and it helped me understand interfaces a lot more!
This is super helpful, precise and clear
Great video, much appreciated!
That's awesome job, man. I'm declaring that from Russia, we don't have such a clear interface explanation even in paid cources
Wishing you had a Spring Boot tutorial 😅 appreciate your content for sure
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
Nice keyboard sound
:)
great work man loved the video keep it up !
Thank you! I adore your videos. 🥰
Awesome video, thanks for making this.
This was very helpful... thank you!
Thank you very much. It was extremely helpful. Good luck.
Thank you broo, your explanation very detail
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.
Very nice. Appreciate the effort.
Also so much better than that over the surface trash Lee is uploading.
Great Video to improve CS Skills
Great video! It was very clear!
Great video, thanks!
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.
Thank you, great explanation.
That was very receivable. Thanks for the info
GREAT VID
wow i feel enlightened
you are so cool, man! please make videos on the complete java collection framework and data structures and algorithms.
Great explanation!!
amazing content brother
Good teaching skills ❤
Awesome explained ☺️
Thanks, Brother!!
Great video! Can you do one for abstract classes as well?

Thank youuu so much !
we all know what " more stuff " he bought on Saturday night , with private method
Man really awesome, but im struggling in 5:14 when you talking about creating variables istantiating interfaces.

Nice job!
Awsome!!
Great tutorial!
You are everything!!!!!!!!!!!! Thank you!!!!!!!
Great Video
Thank you!
Great content
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.
very good, thank you.
Wonderful, thank you.
Amazing, i'm mexican it's easy to understand you
Awesome!
weirdly i tried to go along the video and do the same in Intelj Idea i made sure everything was the same even names of the class and interfaces, but i got errors in places where there werent in the video , like overrriding printStuff method , it highlights the parameters like there's a mistake , what could be the issue?
commenting to help the algorithm
Bro awesome , please cover all basics by weekly videos 😎
Thank you
Have you thought about making a Java course? Excellent explanation.
Thank you!!!!
THANKS A LOT !
When would one choose to use Interfaces over. Abstract classes, and vice versa?
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
Great video! This is a really side question, but what are your thoughts on developing mobile apps using Flutter(Dart) or Android Studio (Java)
thank you soooo much!!!!
I gotta learn your key combo's
Can you do a video on intellij keyboard combo s especially the useful ones? Ty dawg
Thank you very much, sir.☕
AMAZING!
parent class/ children class;
super class/ sub class;
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
Bro make more videos in Java. Your videos are quite interesting to watch :-)
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!
