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!

[@eshwarnag]

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

[@parthdsoni]

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 🙏

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

[@p0pka_enota]

Very entry level explanation. Honestly from an elite software engineer, I expected something like when to use checked vs unchecked, design considerations, recommendations, etc.

[@wieneroach2280]

absolute legend, i am 13 and i started coding 1 week ago, thanks

[@kazaakas]

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

[@sategie]

Old but Gold! This is the best explanation of Exceptions I have ever heard! Thanks a lot for this!

[@jamilxt]

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.

[@abdullahsaid4765]

Just in one sentence and Clear 😀

[@jamilxt]

@@abdullahsaid4765 Yeah. ^_^

[@pranavnyavanandi9710]

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?

[@jakubdudek4133]

@@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.

[@zeppelinmexicano]

@@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?

[@ndk8111]

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.

[@leander415]

Code with John is the alltime java GOAT!

[@flytoinfinityvivi]

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 (:

[@ljront3126]

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

[@SarahRahim-e1y]

This is a very clear explanation of checked and unchecked exception concepts

[@StefanStefanov]

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!

[@ujeshnada5141]

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.

[@asdakak6141]

10 mins video explains better than my 2 hour confusing lecture and ppt lol!

[@JollyFrogGaming]

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.

[@alexzink4451]

Hello, John! I love ur lessons. U'd really make my day if u talk about supressed exceptions 🙏

[@mohamednibras53]

Simple and crystal clear explanation

[@sanchitsingh7089]

hands down best explanation out there

[@manar2404]

you explained it better than two-hour class, can you explain GUI components

[@angurishudesu]

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

[@yasminaitmaksene5230]

Hey John, Your videos and explanations are by far the best i've ever watched ! Thank you so much for sharing your knowledge.🙏

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.

Again great vid. I recently finished a section on Exception. This was a very good synopsis. 🙌🏿🙌🏿🙏🏾

[@リンゴ酢-b8g]

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.

[@HR-pz7ts]

So it's basically compile time vs runtime exception comparison.

great explanation man !!!

[@stephenweber33]

Maybe I oversimplify. Started with an AppleII+. (Nowadays the IDE is a bit better.) ) I have checked exceptions are those that an IDE can find. And Unchecked exceptions are those that would generally require an IDE to be an AI coding for us... You have been hitting most of my internal thoughts somewhere in your video. Perhaps I am mistaken. Most of my life I just added print statements into the code and figured out where the error was based on which print statements returned or didnt return.
