Hey John!! Your explanation is always to the point.. as 5 years of experience developer in Java technologies, I really enjoy your videos men.. I watch your videos to brush up my core knowledge.. keep up the good work buddy.. THANKS 🙏
8:33 In Java, RuntimeException & all of it's subclass exceptions are "Unchecked Exception". Any exception isn't a RuntimeException is "Checked Exception", including "Exception" class.
It's wierd though, why would it check for some exceptions and not check for other exceptions? It checks for FileNotFoundException but not NullPointerException - why?
@@pranavnyavanandi9710 Hey, good question. I am still learning Java so I am not THAT sure of my words but by logical point of view there are these 2 typs of exceptions mainly because CHECKED EXCEPTIONS are much higher in terms of failure risk of application. On the other hand UNCHECKED EXCEPTIONS like NullPointer have lower risk of failure and are mostly caused by programming mistakes.
@@pranavnyavanandi9710you probably found the answer to your question about why Java doesn't check for all exceptions at compile time? If not, it's because the compiler cannot possibly discover how you are going to munge a number, for instance, at runtime and create a NumberFormatException. Especially if there is user input during runtime where the user can type in garbage, there is no way a compiler will ever see that future event, right?
yet again, the last part was illuminating. many videos, I click them open some of these videos thinking, I know all this, but I will always find something that I didnt know
Best java videos ever! No hard to understan jargon terms. I always watch your videso before I even delve into the subject and I still manage to understand all of it. Please keep up the good work (:
Thank you so much!!! I had this question on an interview, was not prepared so detailed fot it, but after watching the video, I am more confident! Thank you again and looking forward for another video!
Brilliant. For once I grasped it. “Checked e” - is checked at compile time and extends Exception, it needs to be caught or throws to go away. In contrast, “unchecked e” extends Runtime exception and are not checked by compiler during compilation.
I really enjoy watching your videos. Your explanations are so much clearer than the ones in my sourcebook. You've helped me a lot over these last few months. Thank you.
Very entry level explanation. Honestly from an elite software engineer, I expected something like when to use checked vs unchecked, design considerations, recommendations, etc.
Been watching your vids to try to catch up for an exam. Definitely helpful! Could you do any vids on networking in java? Stuff like client/server, sockets, udp/tcp.
You are sharing excellent knowledge in easier way. I just seen your video from suggestion but then I saw atleast 5-7 videos from channel immediately. Great way to explain things with code (btw which Eclipse theme do you use ????), things became easy to understand when a programmer see it with code prospective.
Learning point. Checked exception = Checked during the compile time and throw compilation error if we have not handled them. Unchecked exception = compilation will pass successfully but expect to have runTimeException. 1. RuntimeException and its subclasses are unchecked, everything else is checked. 2. I can throw RuntimeException without any compilation error. So, whenevery we throw that remember to catch it somewhere in code.
Hey John -- really enjoy your videos. Are you planning on releasing any java design patterns videos (e.g. Factory, observer, etc) in the future? Would be very helpful! Thanks
Notes for myself: Exceptions are errors in the program basically, you have to deal with unchecked and checked exceptions by try catch blocks basically Difference between checked and unchecked exceptions is that JAVA doesn't CHECK to make sure you're dealing with exceptions at compiled time for unchecked exceptions Any exception that isn't a runtime exception and all subclass of it are CHECKED exceptions - Checked exceptions are CHECKED by java before compiling successfully (in the code itself) - Checked exceptions give compiling errors In java, the __runtime exception__ and all subclasses of it are UNCHECKED exception - Runtime exceptions dont give compiling errors - You wouldnt see it in the compiling stage, only after compiling

I wil tell my children that you are the reason they have food.
lol
lmao
And soon theyll tell the same to their children XD...
Also he is the reason why you have beer 🍺
I thought I am no good in programming and I thought I hated it. But you made it so simple and I see tremendous progress. Thank you much!

Just in one sentence and Clear 😀

What an inspiration. Hi, I'm Tam a Medior Java Developer from Vietnam. Nice to meet you. Thanks god that I found your videos.

Best explanation I've seen anywhere. Whether for beginners, or senior engineers coming from different langauges.

Code with John is the alltime java GOAT!
Old but Gold! This is the best explanation of Exceptions I have ever heard! Thanks a lot for this!
absolute legend, i am 13 and i started coding 1 week ago, thanks
Hello, John! I love ur lessons. U'd really make my day if u talk about supressed exceptions 🙏
I am a trainee of Java-language's course and i enjoying the distending explanations' videos of your channel. They are enriching and developing :D

totally agree, just bare information from wiki, not explained the main difference between checked and unchecked exceptions
You are the greatest. Your explanations are so crisp and precise. Kep up the great work
Your videos are “Exception-al” ❤. Keep sharing 🙏😊
Best explanation I've ever seen on this topic. Thank you very much!
Hey John, Your videos and explanations are by far the best i've ever watched ! Thank you so much for sharing your knowledge.🙏
same thoughts!!
Your videos are soothing to watch....I can understand in one go...it gives me more clarity then before
10 mins video explains better than my 2 hour confusing lecture and ppt lol!
This is a very clear explanation of checked and unchecked exception concepts
This guy is so good at explaining! Kudos!
Amazing explanation. You are a gifted teacher brother
Thank you John !!! As always amazing content.. !!!
Thank you again for such a clear cut explanation with good examples!
This is great stuff. You explained it like no other. Your voice clarity and intonation is amazing.
hands down best explanation out there
you explained it better than two-hour class, can you explain GUI components
Awesome tutorial John! At last one clear explanation for this difference!

Awesome video. Always had a hard time wrapping my head around exceptions, it makes much more sense now !
Its amazing how much we learn from your videos. Thanks a lot
This is crystal clear!! John you are a great teacher!
Learning point.

1. RuntimeException and its subclasses are unchecked, everything else is checked.
2. I can throw RuntimeException without any compilation error. So, whenevery we throw that remember to catch it somewhere in code.
brilliant lecture.. especially that exception hierarchy which you explained
Thanks Java creators for this shot in the leg
Brilliant way of explaining java stuff. Awesome!
Another well explained video!
Wonderful explanation Thank you and the everything is explained in right pace
Very well explained John, this video helped me a lot to better understand this topic :)
Again great vid. I recently finished a section on Exception. This was a very good synopsis. 🙌🏿🙌🏿🙏🏾

Could you please do one on Serialization & Deserialization
Better explanation than my university
Notes for myself:
Exceptions are errors in the program basically, you have to deal with unchecked and checked exceptions by try catch blocks basically
Difference between checked and unchecked exceptions is that JAVA doesn't CHECK to make sure you're dealing with exceptions at compiled time for unchecked exceptions
Any exception that isn't a runtime exception and all subclass of it are CHECKED exceptions
- Checked exceptions are CHECKED by java before compiling successfully (in the code itself)
- Checked exceptions give compiling errors
In java, the __runtime exception__ and all subclasses of it are UNCHECKED exception
- Runtime exceptions dont give compiling errors
- You wouldnt see it in the compiling stage, only after compiling
So it's basically compile time vs runtime exception comparison.
