Just to say, i'm an IT student and whenever i see something new about Java in my college i go here to yt and look up on your account since i found out that you're much eaiser to understand than my professors, asistants and mentors are. THANK YOU FOR MAKING ME PASS MY EXAMS!!! xD
Ditto, he explains everything so clearly, it's insane how much more i can understand from here than from any of my classes lol
Same, but for me i think its the excellent live coding that makes it so easy to understand :D
Thank you for imparting your knowledge to all of us on TH-cam! I pay attention to the Java lectures at my University, but you have a way of explaining it better than my professors.
The best Java instructor out there. Your videos are a binge watch thing. Thanks for making them simple and interesting. ❤️
Thanks for helping us all through Dev School John, you're very articulate and entertaining to boot! I'm sure i speak for us all when i say "We appreciate you".
Thank you John. You always make it easy to understand. You've really helped me, you have no idea.
John I just want to say thank you. Your videos and explanations are so helpful.
Subscribing because I’m in class for Java now and your videos have literally explained the content 100x better than the block of instruction. Thank you for being so clear!
Thank you for giving a real world example of when a "finally" block makes sense to use! Knowing real world examples of why/ when a particular thing would actually be used is a huge step for me in understanding a concept. A lot of times things are explained without showing a real world example of when it's needed and I get hung up on the thought of "why not just do this other much more simple thing that seems to do the exact same thing?"
3:57 - It's exceptional how you tackle the topics of your videos so comprehensively in such a limited timeframe. I wondered why a colleague of mine could not explain to his students the hierarchy of exceptions, while you cover it in the basics of your tutorial here.
Your videos are so good that I'm constantly thinking of designing a worksheet where one of your videos is the topic and my students have to prepare the topic of the lessons with the help of both - a flipped classroom principle.
And before I had actually finished your video, I was thinking about whether you would cover the execution of code after an exception is thrown, and voilà, you also covered that at 9:44.
Please continue making videos about Java related stuff.
In my experience people who don't have a complete understanding themselves have problems explaining it it others :D

Best Java teacher I have ever had. John explains almost any topic in a very understandable way. Thank you very much for your work.
You are nothing less than blessing to us Java programmers, Thank You John.
40 minutes watching videos about Exceptions, and I only understood it after I saw yours. Thank you very much!
Hi. John! Enjoying every single one of your videos. I just wish you were around when I was back in college. You would have saved me a ton of time spent reading all kinds of manuals. Keep up the great work!
Thank you for taking the time to make these videos! Clear and concise as always, I can't be the only one who gets sad when they search a topic they are having issues with and don't see one of your videos addressing the topic/issue.
This was the best video I could find for a refresher on how to handle exceptions. Very well done!
Thank you for taking the frustration out of learning Java. Your content is relatable and easy to understand .
Thanks for these explanations, John! You're the best resource for clear, concise yet comprehensive Java tutorials!
This channel deserves more reach!
I love your content! Thank you
It's great to have someone explain clearly these very important keystone concepts in Java! Thank you!
I am a non IT background person and doing a course in IT currently and your videos are super simple to understand. Thank you!
Good advice to use Finally{} to close connections, etc. Then no matter what might explode in the try { } it won't abandon the connections or leave files open.
Amazing! thank you for taking your time in all your videos, it really helps!
Thank you John for all the videos, exceptional explanations.
you have no idea how much I'm grateful to you! thank you so much John
How does it become so SIMPLE when it is YOU who explain it 😃 Another great video, thanks !
John, thank you for your simplified explanation.
Thank you for the beginner friendly and accessible language and context breakdown!! ;-; So much much educational content assumes a certain level of knowledge that makes learning really frustrating when struggling with comprehension. Definitely coming back to this channel to help study class concepts!
Thank you so much for your videos I am studying a java module and I just wish they explained stuff as simply and nicely as you do!
Great man, soo simple and so much in so little time. Perfectly synced video!!
Thanks for the video! It's fun to learn about fringe cases like the return statement in finally :)
Thank you very much for taking the time to explain this subject in such a magnificent
way.
Bro, thank you so much! Your videos are amazing, as a java developer myself, I learn so much from your videos! Even with one year of experience already. God bless you bro and regards from Russia!
I so enjoy your videos John. Every time like illumination. So clear, concise but comprehensive. Thanks a bunch!
Awesome, thank you!
My dude, I absolutely love your videos. I'm currently 2 years into my BA in CompSci and whenever I don't fully understand something I watch your videos and It makes it a lot more clearer. I usually watch slowly, coding along with the video and adding notes as I go. The way you explain things is just leveled up way beyond any of the university CompSci teachers I've encountered. Also you seem like a cool dude lol. Was wondering if you were ever planning to add to your Java course? Most of the topics within, I'm pretty comfortable with. Just curious if you were ever thinking of going further ahead into more like intermediate (idk?) level concepts, maybe like DataStructures/Algorithms etc.
Very helpful & crystal clear explanation. Thank you.
Man, your content is just amazing! Thank you so much! 🙏
I understand you better than my university teachers who explain it in spanish... ¡Keep it going! ¡Greets from Argentina!
You're a great teacher John; thanks for sharing you're knowledge with us :)
Cant believe this dude doesn't have million of subs. Many time I just watch those videos recreationally haha
Thank you John, your channel is soooo coool! Hats off
Legendary explanation! Thank you so much, John😄
Handle this exception! This was an EXCEPTIONally useful video tutorial!
Excellent video that makes this crystal clear
Your videos are really really good and easy to understand, thanks a lot
Thank you for your videos! They helped me a lot!
Tomorrow is my external exam watched this now. Understood each and every concept will always be thankful to u!
Ty mate. I was searching for why the finally block even exists for a long time. But now that i know it too runs even after a return is called, it pretty much clear
wow this video blew my mind! very insightful and easy to understand, thank you.
Subbed and liked, this guy is great at explaining, Thanks John.
Thanks. I appreciate the easy of explaining the concept
I have assignment deadline in one day and 10 hours and you just saved me so much time, I think I can finish it If I dont sleep tonight Thanks!
Thank you very much Sir
You're a great teacher
Thanks for the last example
Cleared all my doubts
Thank you for this simple explanation! Helped me a lot :)
You are an awesome teacher and code writer. Thank you.
Brother you are saving my college career. The videos are so easy to understand and help me a ton. thank you so much
soo clean, clear and concise. Thank you.
Hi John, thank you very much for your impressive contents. We've learned a lot from you in a simpler way, I remember when I was watching your Java generics videos and I was telling my friends that you're the go-to instructor. So, one simple request, could you possibly produce a playlist on graph theories, graph travels and algorithm that goes with graphs?
So helpful every single video!!! Thank you!
Way better explanation than my algorithms and data structures prof gave. Thanks!
You're the best thing that happened to Java since James Gosling
Thx a mill John. Despite the value of your java tutorials, they're actually quite entertaining.
Your video is very informative, thank you for taking the time to help all who need java help
You are simply genius!🙌🏻
I just started watching your videos and am really impressed. You explain things very clearly and precise. My one question since I’m newer to Java, do you have any documentation or direction on how you move through your code so quickly? I know some of the basics but you move through your code very fast and effectively.
i dont sup to many channels. but you deserve it so much.
best channel explaining java concepts ever!!
John’s the real MVP!!! 🙌
To the point videos. Keep making good content John.
2:33 You aren't alone John! It took me my 90+ pages teacher's notes- where this was written over and over- a 2hour lecture and finally your video to understand that LOL
this is first time when i saw your video. I hope now i can learn whole java coding here
Very clear explanation. This man is a god!
Thanks John. Super clear!
The way he describes Java.. I am encouraged to become a developer now😊
Thanks for the very good explanation, great job! a couple things I would add to the video:
Autoclosable and try with resources (you did talk about DB connections/Files you wanna close in finally block, would be great to mention Autoclosable there too).
But I see that you have a separate video on checked vs unchecked, which I was about to suggest putting here as well, perhaps there's another one on try with resources too.
All in all, thanks again and keep up the good work!
better than my java teacher, awsome video!
I like how my man calls method print but what it does actually is returning value :D. You are my man for naming :D
thanks for clear explanation
Bruh you are a life saver .
very helpful video, i learned a lot
bro you're very helpful🥺
thanks a lot sir
Love❤ From India U r Simply Amazing😊 it feels like whatever the Concept be it becomes easy when u explain it
Thanks for these videos.
That final part about the finally behaviour was quite interesting.
thank you! that was extremelly interesting!
Hello John,
Thanks for such wonderful tutorial.
One thing that you have missed about finally is, finally is not executed if System.exit(0); is called
Ex.
package test;
public class FinallyExample {
public static void main(String[] args) {
try {
System.out.println(3);
System.exit(0);
} catch (Exception e) {
System.out.println(4);
} finally {
System.out.println(5);
}
}
}
and finally, instead of using finally you could use try with resource
top tier tutorial, thanks man.
Thankyou John. Good Explanation, Please Make more videos on Servlet,JSP,Spring,SpringBoot,Hibernete.
Thanks for the great video!
Top notch video over the internet! I am really appreciate it! Sir, where from are you?
hello john, i learnt java by watching your tutorial videos you makes me easy to understand and i'm very thankful to you....
will u do videos about user-defined exception....thank you
Great video as always!
Great as always. Thank you sir! :)
Thanks for this amazing tutorial! I've been always wondering what's the difference between writing a code after try-catch block and in the finally block.
Also you can use try with resources block, to close all connections, without needing to use finally block.
You really make me want to learn Java
Best Java channel
bro my uni uploads shitty presentations and if youve missed something tough shit. thank god for your channel.
Great video, thank you
What an exceptional video!
You are amazing man....
