- What's the difference between the Checked and Unchecked exceptions in Java? We'll talk about what exactly the difference is, and what it means for handling checked and unchecked exceptions in your Java programs.
In this beginner Java tutorial video, we'll talk about both Checked and Unchecked exceptions, which kinds of exceptions are checked and which are unchecked, and how you should handle both exception types.

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!
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 🙏

Whats that
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.
Just in one sentence and Clear 😀
@@abdullahsaid4765 Yeah. ^_^
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?
What an inspiration. Hi, I'm Tam a Medior Java Developer from Vietnam. Nice to meet you. Thanks god that I found your videos.
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.
Best explanation I've seen anywhere. Whether for beginners, or senior engineers coming from different langauges.
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!
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 a lot, John, for your explanations, they are so structured and clear! I am glad to find your channel here :)

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
Hey John! Your way of elaboration is simply awesome , keep that good work for community
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.
You explain these topics very good. Thank you for your effort.
This is a very clear explanation of checked and unchecked exception concepts
Wonderful explanation Thank you and the everything is explained in right pace
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!!

Hey John, Thank you for the clear and concise explanation!
Super informative! Thanks for the explanation!
Thank John finally an easy way to understand this topic.
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.
a great knowledge! thanks a lot
Great great explanation !!
