Java exceptions look scary, but they're actually a friendly message that gives you loads of information for how to fix your code. The name of the exception will give you a hint as to what went wrong, it provides an exact trace of which code was hit and the exception even gives you the exact line number where it occurred.
This java exceptions code can be tricky at first... But SURELY you'll get it :) If you followed along, congrats! You learned-by-doing!
I hope you enjoyed this tutorial about java exceptions! I like to have a nice mix of tutorials and actual projects for you all :)

I teach computer science at a high school and refer my students to your videos all the time. You are truly "Exceptional". :)
@Steven, what you are doing as a teacher is great! It doesn't make you worth less, only on the contrary!
"exceptional" we see what you did there lol
Missed opportunity to call your program "Exceptional"
you will make a good engineer, my friend. Lmao
that moment when you name your program or even your methods/variables something funny and then have to think about what it was supposed to do.. so yeah exceptional :D
Absolute hero. Since discovering this channel a couple weeks ago, I no longer waste time listening to my Intermediate Java prof's online "lectures," and just note which Alex Lee videos I need to look up.
He should make a Patreon for people who can't quite afford the full course, but want to chip in for all the help he shares on UA-cam!
he does. Support him at www.patreon.com/alexlorenlee
Alex, you are such a wonderful person. You are so honest. You did not learn these exceptions at college and trying to teach us. Great lesson.Thanks
Honestly, you are the best Java instructor ever. Thanks
Thank you. This is on my final exam coming up, yet I swear we didn't go over this in class at all.
i really like how he always mention how teachers makes things hard for us sometimes, well you definitely made some things easy for me so thank you.
Once again, well done. Incredibly grateful that you take the time to actually explain things at more than just a surface level. Though many things don't require more than simply the knowledge that "This does this", it definitely helps some of us to grasp the concept when we can understand the theory.
Man, you have no idea how much i love you .
I love how your videos are so short yet full of good information. Thank you so much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Usually if I see the dreaded red text, I get frustrated. Your video reminded me to just read what the program is saying, and I can figure it out. Love your videos!!! Thank you :)
Thanks Alex, I am in my third semester for my programming degree and I dont have the best professors. Your videos really help clear up alot of the things we miss in the classroom.
Alex whenever I watched your videos to learn stuff, at the very start of the videos I always got a boast of motivation from your. Which keeps me away from all negativity and helps me learn better. Thank you:)
You are better instructor than any professor I've ever had, thanks for the videos.
"I'll catch in the next video"
First you gotta *try* it, then maybe *finally* you can do it, haha
Thats right lol
what about continue doing it :thinking:
lmao
OMG BROOOO!!!!!!!!!!!!!! TEACHERS ARE SO BAD AT TEACHING THIS IM SO HAPPY I FOUND THIS!! I'M CRYING IN JOY RIGHT NOW MAN!! THIS IS GREAT
Thank you man. Seriously appreciate all the quality content. You keep me motivated and grinding learning this content when it has been tough learning this new language. YOU ARE MY GO-TO FOR ALL OF MY JAVA BENDERS hahahah.
Thanks :)
"You might have heard of the word exception and wanting to stop programming right there because teachers do a horrible job at explaining..."
Oh boy, you got me right there. I cracked up laughing so bad at this because it IS SO TRUE!!!!
Love your video, Alex. I'm college student too and sometimes the profs are so bad in explaining and honestly your videos are the BEST! I appreciate it dearly!

Nice videos. You did explained Exceptions very well, but it was also helpful if you could do a videos on how we should handle the Exceptions. So that we can still run the remaining of our codes, even after an Exception.Thank you
Clear explanation useful video thank you @Alex

Very well explained!
Hi, Alex, Your video Helps me a lot with reviewing java basic. Thank you, I wish you could update more java intermediate level tutorial!
When you were talking about teachers doing a poor job at explaining exceptions, I immediately thought "wow, so relatable!" Then I saw your NC State shirt and now I understand why! Wolf pack!
thank you for explaining this so well :)
Great work!!
Hey Alex, I am a German Student and I have to say, you are able to explain much better than my prof. in my nativ language ;D

Ending music: Kazura - My way
Ur The Best Love your vids man !
Good Job!
i love this guy. he has a degree and a personality.
Omg what a explanation superb
They never thought us too. All these exceptions and error handling portions were left in the air to be explored by us. That sucks.
Thank you so much!
Bro you have to be one of the best explainers on yt
I wish such kind of tutorials were available when I was in school some years ago - it just would have been so much easier. Kids today are lucky on this topic!
Would be much appreciated if you made a video about checked and unchecked exceptions
You are good! Thank you!
I liked your videos so i subscribed :) Can you tell me which video editor you use ? How do you manage to bring that notification bar at bottom ?
Thank you!
As. ALWAYS short vids and super beneficial
You are the best! Thank you!!
Thanks it was really helpful.
Can you please make a video on how dynamic binding and polymorphism is demonstrated in the code?
amazing vid ! thx
thank you alex you helped me
I'm a resent graduate of Full Sail University As a Game Designer . I am Currently Cross Training as A Software Developer . My Knowledge of C# Coding Has helped me pick Java Pretty Quick . Youre Videos Go into more Detail helping me to understand. what I am learning with Revature. Thank you for you video they have been a great help. over the course of this week
Thank you
All objects within the Java exception class hierarchy extend from the Throwable superclass. Only instances of Throwable (or an inherited subclass) are indirectly thrown by the Java Virtual Machine (JVM), or can be directly thrown via a throw statement.
You are my Hero, thank you!
You make me laugh and learn. Love you
Great! thx!
Please explain deeper in the future, looking for more of your videos
Great tutorials!!!
This is much more friendly than error in c++
you're the best Alex :)
Thank you)
hey alex I got a question, so in prev video on arraylists you didn't use the "" part with arraylist but it still stored strings so why did you use this in this video, any specific reason?
Great video! Got anything on User-Defined Exceptions?
You are a hero🙌
Good explanation and how to debug the exception
can you make videos on -
immutable class
Custom exception
Singleton class
Comparable and comparator
pretty cool keyboard u got!
Where did you get your mechanical keyboard laptop extension from?
You are the best teacher in Java Your videos really help me in school .... but i can't find your video for throw and throws in Exception handling .....
Can you please make a video about enums? Great vids btw!
Yeah!
Thank you very much!
Perfectly Explained, thanks. What's the tittle of the song playing in the background, at the end of the video? I love it.
Please make video with nested exception
best teacher ever
I love your keyboard, I wanna buy-it too, you mind sharing where you bought it from. Thanks
Maybe a little late lol, but its at the bottom of his video descriptions. It's got a hefty price tag
Hi, Alex and everyone who reads this and may benefit from it. Even though it is good to use for explanation it is not good coding practice to ever catch IndexOutOfBoundsException (unchecked exception), because this is probably programmers mistake if something like this ever happens and it should be fixed (with simple if condition) instead of try-catch :) Same goes with deviding with zero etc.
I love your keyboard, where can i buy one?
You diserve 1m subscribers🙏
good explanation mn
Great video thank you so much for posting this! I think there is a little mistake at @3:10 when you said Java can't turn the code into machine code. Java did turn the code into Java byte code(machine code) because you were able to compile the source code. That particular exceptions was thrown during runtime not compile time.
I think he’s just trying to explain it in an understandable way for beginners. Once you begin to grasp what an exception is in the first place, then it’ll be easier to start getting into compilation vs runtime errors. But to a beginner, it makes no difference. All they need to know at this point is that something went wrong.
Absolutely 100% wonderful video but dang I need that old looking keyboard XD
where can I get that beautiful keyboard of yours?
Thank you 🙏🏽
Would have been nice to have a thing or two about exception handling. This video is more about how to read exceptions...
What text editor are you using?
Can you please make a video about sorting. Your explanations are the only ones I understand.
