I’ve been in the industry for 8+ years and sometimes I forget the basics. Thank you very much for the effort. You are a brilliant teacher. Respect ✊ ❤️
Excellent. I can hardly think of anything to add that wouldn't make it too long. Some people might think "Who needs this crap anymore, we have lambdas now and they are even neater!" That is more than a little true, but here's a couple of restrictions on lambdas that don't apply to anonymous inner classes: Lambdas can only be used with Single Abstract Method interfaces, and can only override that single abstract method itself. An anonymous inner class, on the other hand can merrily override more than one method, or can do even more, tho it is a good idea not to get carried away. If there's too much in it, give that sucker a name. An anonymous inner class can implement any interface, not just Single Abstract Method ones, again, best not to get too carried away with this but the language won't stop you, and can also subclass any abstract or concrete class if there's a good reason to. So lambdas are great, but it would be premature to throw Anonymous Inner Classes out of your Java toolbox.
How does this guy not have more subscribers? Straightforward, to the point explanations that are well presented, and importantly no needless filler. Just awesome, you've earned my like, sub and comment!
I'm going to write an exam about Java tomorow. John, you are saving me from letting it be a total desaster. Your explanation style is wonderful and you have exactly the right amount of humor in your videos. Your explanations and your English is very good understandable, even for a non-native English speaker on level B2. I honestly watch your videos as they are the best to understand, motivating, not too long but have everything important in it. You are doing a great job! Thank you and please continue like that!
You are one of the best teachers I have ever seen, you and another that I won't mention here out of respect. But I think that you videos are the clearest of any teacher that I have seen online, period. I love your videos.
Seriously cannot be stated enough: you produce the most easily understood, time considerate, and useful programming tutorials, period. From a 35 year old junior engineer: thank you ❤️.
can't thank you enough for your videos i am starting a new job as a junior java programmer in May. I had used lots of your videos to prepare for the inverview and am using them now to prepare for the job itself. thanks :)
Hey man, I just found your videos, I just want to say that I love you 🤣. You're a genius, I get to understand these complex topics easily in quick, short videos.
This helped me understand some code at work. There is an anonymous class that is implementing an abstract class that takes in a Generic Type which implements an Interface with a Generic Type. So public abstract class PortalAsyncCallback implements AsyncCallback and the anonymous class is actually only overriding the methods from the AsyncCallback Interface.
You are really the best!!! Every single time I need help I come to see your videos and even if I m not 100% good with english you make it so easy to understand!! THANK YOU!
I love java, I'm reading The Java complete reference 11-edition and doing some online course, I think I just found the java grial in your channel, good content, thanks man
Hey John , Whoever you are ,wherever you are from trust me you are a genius. To possess a knowledge is great and most of the humans can inherit it but the toughest part is to share and make other people learn in the most simplest way and thats what you actually do. I myself have been into coding for past 10 years but when it comes to explaining things to someone I always find it difficult to look for examples and to do it in the most efficient and effective manner. Anyways ,was here to brush up on few interview basics and subscribing your channel to keep myself updated and come back again. Thanks again . Cheers!
I Totally agree with the guy that wrote Im not kidding whe I say you´re the best Java Teacher but to help the purpose of the channel im creating another comment
Thanks a lot for making this video, your explanation is super easy to follow, you are a very good..... great teacher. I was trying to use an anonymous class for multi-threading with the run method and boom!!!, it was your second example. Thanks a lot.
OHhh, so those are classes, good to know. It's also nice to know there's a way to make a class that can only ever have one instance of itself, because I wanted that for something I want to do in the future, and will probably use it for many other things.
hi John, I've been loving your content so far, I wanted to give a suggestion if you don't mind! One of the things we wonder as we learn new concepts, which you make it very easy to understand is how we could/would use this in a real world situation, because obviously the examples used are simple (so we can understand), so perhaps it would be nice to add some "real world scenario" use case, just so we can have that extra "ahhh that makes sense" :D
Hahahahaha i cannot believe that you replied to me thanks man i really appreciate the efforts you're making and the awesome explanations (Btw my exam is tomorrow hahaha)
I have been traveling on 🌍 Earth with Java for 10 years just 5 miles, but after watching your video tutorial approx 6:26 minutes I have traveled with Java 24,887.64 miles which is exactly the circumference of the Earth. Now I am 🦋🦋🦋 flying with Java in ✈🛩🪐. A lot of thanks. I really appreciate.
LoL really appreciate the creative tutorials that you made, every time that I see your smile can't hold myself smiling too, I wish that I had a tutor like you in every subject in my learning journey big thanks and hugs to you
well made vid, thanks. “one-time-use class with an interface”. jesus, I love how much easier this is in JS. that is just a simple variable. strong OOP is jaded 😂
You are THE BEST. Never stop making videos!! I have a question. Can we include fields in an anonymous class? I read we cant because we can't include a statement in a statement but i'm not conviced!
Your videos are amazing and the best thing that you explain very important things in the easiest and shortest ways. Would you please make some videos a bout Spring framework (web) thank you 😊
Legit just clicked on the vid and need to bet that the thumbnail's a suburban sasquatch reference edit: damn (also real talk I love these videos, they're a wonderful supplement to a free online course I'm doing. might check yours out later!)

This is so validating haha

Sounds like you know more than enough to be doing your own videos!
Your lessons are prompt, easy to understand, and generally fun to watch. A perfect way for me to brush up my rusty Java skills. Keep up the good word!
How does this guy not have more subscribers? Straightforward, to the point explanations that are well presented, and importantly no needless filler. Just awesome, you've earned my like, sub and comment!
Ur carrying my uni courses so hard, thanks a lot man!
Happy to help!

I spend about two hours every day with you John. We will land a developer job in 2022!
Have u landed a job
@@dataslid I have my first interview today!!!
@@tresaidh3y90 I wish u luck🤞
Good luck, let us know how it goes!
These concepts are deep and no one teaches this indepth. Glad that I found this channel.
The best vides of Java...Thanks a lot
You are the best teacher I've ever seen
You are one of the best teachers I have ever seen, you and another that I won't mention here out of respect. But I think that you videos are the clearest of any teacher that I have seen online, period. I love your videos.
The clearest way of providing information!
Really a cool guy
It's amazing how I can see and even use something fairly often and still gain insight here about what I'm really doing. Thanks.
Best Java teacher I've ever seen. And most sympatic one aswell
Thank you for your tutorials.
you are the best java instructor
Sometime I confuse you with "programming with mosh". Big fan of both of you!
Mosh is awesome! Another bald programmer with glasses.
Seriously cannot be stated enough: you produce the most easily understood, time considerate, and useful programming tutorials, period.
From a 35 year old junior engineer: thank you ❤️.
Everything you teach is clear and understandable.
Best explanation ever, after going through many tutorials of Innerclass concept. You are one of the Best Teachers.
can't thank you enough for your videos

SIMPLICITY; simply great, regardless the not so simple content!
Interviewer: So what is an anonymous class in java?
My brain: 2:21
hahahahahha good one
Amazing work! You explained incredibly this topic that was bugging me
Glad it was helpful!
thanks a punch for your simple, direct and nice explanations
I wish you were teaching at my school, your tutorials are the best

Yep, still the best explanation I could have came across
Great channel, super clear explanations, always clearly explaining something I didn’t quite understand before. Cheers

It's always worth to watch your videos till the very end! xD
YOU ARE THE BEST U HAVE BEEN SAVING LIVES FOREVER
I had no idea anonymous inner classes could save lives!
Hahahahaha i cannot believe that you replied to me thanks man i really appreciate the efforts you're making and the awesome explanations
(Btw my exam is tomorrow hahaha)
Good luck, let us all know how it goes!
@@CodingWithJohn yess for sureee
@@CodingWithJohn it was really difficult , mostly about stream but i did what i could
Perfect articulation. I like it!
Simply to the point...
You are simply awesome. Thank you so much. You demystify Java programming.
Another great tutorial, thank you very much John!
John, you are such a talented teacher! 💫
Brilliant tutoring.
voice of big foot lol, best teacher ever!

Sir, please make a video on Singleton classes.
Awesome video as always. Thanks John!
well made vid, thanks. “one-time-use class with an interface”. jesus, I love how much easier this is in JS. that is just a simple variable. strong OOP is jaded 😂
Thanks for explaining it in a clear and concise manner. I am definitely subscribing your channel 👍
thanks for the great explanation
Great content John. Please create a course ( paid ) for advanced Java, Springboot etc. too. No one explains Java better.
You're a blessing! 😭❤️
My java instructor... i hope you will do video on generics someday anyway ,best content as always...
Thanks for a great job. Your tutorials and explanations are the best in the whole universe:)))
You are THE BEST. Never stop making videos!! I have a question. Can we include fields in an anonymous class? I read we cant because we can't include a statement in a statement but i'm not conviced!
Great teacher! Yes, one of the best!
Your tutorials are great. Thank you very much.
John, please make a video with lambda explaining
this was so good, thank you!
