Hey Sam I just discovered your channel a couple days ago and think it’s just fantastic. Really easy to follow, and one can tell you know exactly what you’re talking about. Makes me hate my school just a little less for forcing us cybersecurity majors to learn Java.

[@KeepOnCoding]

Java for cybersecurity seems a bit strange. Glad you’re enjoying the content though!

[@DonPierreHalfaway]

First off and foremost... I enjoy your videos. Good way to use your spare time. Microphone and lighting is awesome by the way. Good job

[@lanchi8361]

Major thanks for your video. You're one of the few programming instructors who explains it in a way that beginners like me can understand.

[@alessandrobeato9282]

that's the first video i saw in your channel and it's really good, just saw 3 others video of yours. The explanations are really easy to understand, keep up the great work :)

[@andrethomas4455]

You need to make more videos. You're a gifted teacher.

[@ricardoestrella95]

You don't have enough likes or views for this video for what you deserve; this solved so many doubts I had... Definitely awesome. You got a new subscriber. Keep it going that way!

Hey man Shout out to your videos. They are actually helpful. Also love your setting. Respect.

[@Youssef-pd2td]

Awesome video! I didn't even know the finally keyword until today. Thank you!

[@asedmohamadrezaamini6520]

you are truly a good teacher

Effortless delivery, keep on keeping on mehn. You're gifted.

[@study_in_this_corner]

Great tutorial. I come back to your java content when I am stuck in exercises. thank you.

[@erebosifavour3760]

I love your channel bro!

[@paulodacosta1379]

I wish you were my Java Programming Professor. You explain everything so well. Thank you for sharing your knowledge :)

Exception - An error that occurs in a program during nighttime.

[@JonasKeil]

The tutorial structure is insane!

[@tiend2421]

Thank you for this quick and easy explanation about Exception handling. Even if the new cool kid in town is Python, I still love Java. Even if Java is a statically typed language and is very verbose, it forces me to stay disciplined with my coding. Keep up the good work, mate! Cheers~

[@gustavosantos106]

I didn't know Oscar Isaac was a part time Java teacher! and a very good one! Great video: simple, organized, direct, and clear. Suscribed!

[@kisaflwr]

my teacher took 2 hours to explain this and still failed. loved your video !!

[@johnlinley2702]

Boy, am I glad you did this. Thanks!

[@bulbultripathy6291]

Thank you so much for making these videos!

[@Spagooli]

You explain the topic really well! Thank u!

[@jpetris36]

You never mentioned the hierarchy of exceptions :(

[@nahidahmed3399]

great video man. just one critique. when showing the execution of the code, zoom out so we can see the code and also the execution. helps to better understand what the code is doing. instead you just made camera transition to the run section.

[@johannarodriguez4486]

cant believe an 11 minute video taught me more than a 50 minute class that takes place three days a week did

[@avoid_hitbox]

True

[@patrickrk44]

No lie this at the moment is way over my head. But I never turn away from a challenge and want to learn to code. Not only for the money but the challenge to learn. Already speak 5 languages fluently so hopefully I should pick it up easier then not

[@jscorpio1987]

Hello fellow language lover!

[@kennethazor]

ohhhh! THAT'S what exceptions are- processing errors without halting the flow of the program! Thanks! :D

[@mikhailn4609]

Great vid! Minor comment: 01:40 - not entirely correct. Catch requires Try, however Try requires either Catch OR Finally.

[@avoid_hitbox]

Ash: Gotta catch them all

[@leaxynite3420]

thank you, know i can create my demo in Exception

[@unbekannter_Nutzer]

It's better to write the message in the catch block to System.err, not System.out, so the user can redirect the error stream into a separate log file, or suppress errors altogether (> /dev/null) or suppress everything but the errors.

[@Michael-AC]

What's the difference between using finally and just leaving something outside of the try-catch blocks?

[@zoriiginalx7544]

I'm assuming if the catch blocks tries to terminate the program, the finally block will still run while just leaving code outside the try-catch won't run in that instance.

Hey, thanks for this video. Super helpful!

[@yuhyeonpark9408]

... this is the chapter in the book that I always used to skip...... oh, someone is talking about me!!! lol I'm currently working on my project using Spring framework and ur channel helps me a lot to go over Java again. thank u and plz keep uploading great content!

[@ruwaydajama2143]

I love your video's please do a complete JAVA for absolute beginners !

[@engjellbakiasi742]

Can you tell us all the shortcuts that you use during the video?

[@amandamate9117]

you doesnt covered the structure of expections! like why you use sometimes expection e and sometimes a specific arithmetic exception e. I hate the fuckin internet, you find everywhere infos and nowhere everything together in a quick understandable format. everybody just touches topics. fucken bullshit

[@rajakumaran4626]

simple and clarity is very important and then super and thread life cycle video i want may be sent it

[@MrVeenay]

Hello Sam, You mentioned at 1.41 seconds in the video that we can't have a catch without a try and visa-versa, I can have try {

I think it's already there bro like I think oops video probably

[@JarikKomarik]

Thank you, very helpful !

[@Youssef-pd2td]

Hey Sam! I currently am in the Seattle area and studying CS, I am a rising sophomore in a community college and will have to transfer next year to a 4 year university. I wanted to know what you think of life as a Software Engineer in SF, in the Seatlle area, you get pretty much the same stuff, but you can live in a house for the price of a small studio in SF. I am currently thinking of applying to the UC schools, but I don't know if it's worthwhile. What would you recommend?

[@rishablee6471]

Nice smooth video

Hey Sam which platform are u coding Java on? I use Eclipse and I absolutely hate it

[@KeepOnCoding]

IntelliJ

[@shamshurr]

You rock.....Amazing

[@ghadeerabbas4193]

very cool explanation :)

[@HussainMohammedAshruf]

after finally block is executed does it run remaining lines of codes after finally block?

[@tannerbarcelos6880]

Is try/catch a good/common practice for interviews? I’ve noticed many times if I do a leetcode problem, I go out of bounds but overall I am “almost there” for solving the problem. But I feel like try/catch is lazy handling of the logic in an interview setting? Or no? I’ve never interviewed and still have two semesters left in undergrad haha so I dont know. I’m naive

[@KeepOnCoding]

I’ve never used try/catch in a DS&A interview.

[@theogpill]

Catching exceptions when using arrays would give the impression to the interviewer that you dont understand the data structure you are using. So dont do it. Its like catching an arithmetic exception for a division by zero instead of validating with an if block.

[@joancasals4365]

Why is it that after the return; the code still goes to the finally section of the code?

[@HDbIce-oj3wv]

Is studying flutter worth it?Do reply

[@saurav-sky55]

but you didn't explain why it does not return it was not clear at all please consider clarifying the last statement

[@cristinerosario4935]

If you’re beginner which language do I need to learn?

[@jscorpio1987]

Whichever language is relevant to what you are trying to accomplish by learning to program. Java is a good start because it’s very general purpose. But if you want to learn, for example, iOS development, Swift would be more relevant. For web development it would be JavaScript (which is not at all related to Java).

[@godofkings4366]

nice and simple

[@QuanBad]

Hey Sam! My name is Quan and I have a friend who is developing a game in Java. He’s hit a road block and needs a mentor. I’m on the 2D animation side of things so my skill level at coding is ass lol. I was wondering if you have an email so I can connect y’all together & he can ask about these difficult problems he’s having like clearing a level. Hope to hear from you soon!

[@ahmjksjssd]

beautiful

[@nikhilnanhe3410]

That was good 👍

[@shashankshetty5879]

Brother if u read this plz reply . I just completed oops and I know arrays and sorting . So now I will practise problems on them and parallely learn data structures .. Is that the right way to learn .. 👀 nice video

[@KeepOnCoding]

Yes. Eventually you’ll want to learn linked lists, binary search trees, and hash maps.

[@shashankshetty5879]

@@KeepOnCoding ah ok brother. Ty so much for the reply ☺️♥️

[@BBoysAndTrickers]

anyone else studying for amazon technical academy? funny hes wearing the shirt

[@9SMTM6]

Yeah not a big fan of Java/JS/Python etc error handling, don't really think it's that much of an improvement over C. Try-catch is very uncomfortable to work with, and you still don't really know the type of exceptions that could happen and you're often not aware that some code could throw an exception, which leads to the issues you mention where some rare exception kills the whole Applikation. You then often try to handle that exception with some global error handling, which is tricky to do right and really not elegant. Very much like Null-Safety Error handling in Java should be handled with the type system. Like Rust does it. With Rust you have a "Result" enum provided by the language. Thanks to the match expression (more powerful and expressive switch case) and some provided helper methods - unwrap(), expect(), unwrap_or(), or_else() - you can still I. E. ignore error handling while prototyping (but you do so explicitly and can find it more easily afterwards) or replace an error value with a default or execute some cleanup on errors. And that Result type is generic and thus has information about the error type that also often helps greatly I. E. when different errors could occur.

[@user-em9mw9ch3y]

thanx

[@jiawenli3787]

I love your videos, but I have to say , there are a lot of mistakes in this video , first the definition of exception is wrong, not only while the progame is running have exception ,in fact this 's called RuntimeException , you can't miss unCheckedException when you write your code , another thing is that we could just have try without catch , they both do not have to exist at the same time.

[@innocentrwakigarama3848]

Good job! very obvious

[@amirmachina2346]

Solid

[@manfrombritain6816]

wait so you dont just put everything in try-catch with an empty catch block?

[@avoid_hitbox]

Its called bad code

[@giapcnphfplhn]

I hope you can vietsub in Vietnamese in the next videos

[@Lyes_Abdellatif]

nice

[@poudied8826]

good tutorial but can you please show us the code while you are showing your face. i mean just put your face at any corners of the screen instead of putting it in the whole screen and not showing the code.

[@thisurathenuka8362]

Exceptions can occur at compile time too, bro. They are called Checked Exceptions. (Ex:- FileNotFoundException) . Nice video overall ❤❤ Just be careful to always proofread the script before the video

[@akmaljonmahmudov6120]

Bro go on teaching something new in java.
