If you’re new to programming but want a career in tech, I HIGHLY RECOMMEND applying to one of Springboard’s online coding bootcamps (use code ALEXLEE for $1,000 off): bit.ly/3HX970h
whatever happens happens for good i guess alex u didn't understand things in ur class and for a long time u just did things the wrong way, or memories it or something else but when u know them clearly for the first time - the wrong data in your mind get sorted off and all the points got connected (and u got the true wisdom on that topic) i guess ur fellows in class who got concepts in the first run didn't have deep understanding like u forget shitty talk and genuinely thank you so much for explaining topics so gud ( u r a great teacher bro
I will say Mr. Lee that you do the best job of explaining (in detail and complete) than anyone I have watched to date. You don't miss anything. Most people would not hit 50% of the minutia you do. Great presentation to boot. Your going places....
Alex, every time when I watch your videos I learn from them and at the same time I have fun. You know how to explain the topics with jokes. And it really makes me to understand programming easily. Keep teaching us. Just respect. Please can you make some videos related to selenium and exceptions in selenium?Thanks
Thank you so much for clarifying! You're the only person that I've found with a clear explanation for this error. I just fixed my program! Subs just for this helpful video.
@Alex Lee Hi Alex! can you please make a video of how to use the date format to prompt the user to print an object ArrayList from a CSV file by setting the date ranges. i.e., I want to get a range of dates from 12/30/2022 to 01/22/2023 and ask the java program to print me that range of the date, and everything should be done in a void type method with two parameters. Just so you know, I don't want the date itself; I want to print the date range report, which includes the price, total price, and a number of products all in one table, but I want to use the date range to print them. Thanks.
I have been learning because I have been tracked, not by the law but someone who spent years pretending to be a friend. It's amazing what people do and I offer people to look at what I have in my device, but they prefer to secretly pretend to be police or a 3 letter agency.
Thanks man, this helped more than my teachers at college. All they said was that it exists and makes your program crash, wow I didn’t realize that after my program crashed 😂
@@alexlorenlee But help me with one thing, I have this error in game, but it only shows the error, but not location of it (it shows: Internal Exception: java.lang.null.pointer) what can I do to fix it?
Darmi Games that sounds like a bug in the game itself. If there aren’t any videos on how to fix that error for that specific game, you may be out of luck or have to reinstall it/wait for them to fix it, as the error is coming from their code
how to fix the problem the Null Pointer Exception Java with Jradiobutton I use this object with Mysql . how to fix this problem with JOptionPane thanx.
I made a webview app and then icooprated fingerprint auth..now i have no code error..but my app stops imediatly i authenticate..and i get this null exeption error anay thoughts..?
Hi Alex, thank you for sharing your understanding plainly. I am trying to get some ideas on Java as I've got to work on the IT field. I would definitely watch other videos from you. Please keep up the good work. I hope I could give you some useful feedback in other videos.
Hi Alex only one suggesstion...if its possible for each topic explain little more, i know it can make begineer confused........but to work in real world project we need little more realstic scenrios.........first video can be basic,2nd video little epth andwith more relastic scenrio...
Hello there nice explanation . Tied to create a Generic Array and its not possible unless you are creating an obj from Comparable like T [] = (T []) new Comparable [10] (How is it possible) . T [] = (T []) new Object [] ; also not possible . Class cast exception occurs . Looking for a video from lol . if possible, please upload a video lol. Happy Holidays
Hello Alex, How are you? For the last exemple you do note declare the value of scan does it work if you write the code as below? System.out.println("Enter your name : "); Scanner scan = new Scanner(System.in); scan = null; System.out.println(scan.netInt()); Have a good day ! ig @r.mwepu
hello, i have a question, how i solved a possible nullpointer exception of a returnable variable? for example private int myFunct(){ string number=null; try{ number = "3" }catch (Exception e){ e.printStackTrace(); } return number.toInt32(); } in this case we are setting a variable who start with a null value , and then we run some code, and that started variable we need to be returned but into an int, that could produce some nullpointer exception right?

thanks!
@@alexlorenlee thanks to you

I love you man!! I couldn't solve my problem within 3 days. And solved it after 4 minutes of your movie. Thanks!!

Victor Gallardo that’s great to hear man, thank you!
how you got the error in the first place? like you accidentally code null into the program or what?
the pen analogy was hilarious. thanks for sharing.
Aunque no hablo muy bien inglés, entendí de una forma muy general la razón de ese problema con la excepción.
Gracias Alex lee
Thank you so much for helping me more than any of my teachers Alex!!!
this keyboard intrig me even more than this god damn exception x)
it's actually so simple, thanks for your great explanation!
That pen analogy was fantastic! :D
who is disliking man? cause he is really really good.

is there an example of null pointer exceptions that have anything to do with array lists?
The Empty Box Analogy Was Really Helpful 👍
very nice explanation with full energy

Your videos made it very easy for me to learn Java. Wish you had added a few videos on GUI. Thanks for the help :)
thanks. you gave me a better view of null pointer exceptions.
Thanks allot, i pulled off an all nighter not able to fix it! this helped allot
I don’t understood whats the point of it when we need it
It was not the solution I was looking for, but it for sure is something I needed ! thank you
Thanks man, this helped more than my teachers at college. All they said was that it exists and makes your program crash, wow I didn’t realize that after my program crashed 😂
I haven't known anything about java,but you explained it good,so now I know,what is this error,thanks a lot,I'm subscribing to you

@@alexlorenlee Can't it be caused by mods?
Darmi Games by mods it can, yes. I’d check if anyone else with the same mods had the same error
It was really helpful, thank you!
Ok! Best explanation so far on this. This error gave me lots of headache too.
Thanku so much my dear brother for deep explanation you are genius from india ,tamilnadu
greath explanation of null pointer exeption alex
thank you Alex,

i was very helpful for us.
regard's from India,
Thank you very much.
You talk so beautifully.
You've seen it in the most beautiful way I've ever seen.
how to fix the problem the Null Pointer Exception Java with Jradiobutton I use this object with Mysql .
how to fix this problem with JOptionPane thanx.

This analogy was very useful, thanks.
Can you pls do a video explainig what exactly "throw" and "throws" mean and what they do?
I cant find anybody that explain better then you do
if you can do a video about threads in java
Thank you So much.... calling method form null object and it throw null pointer exception that make sense to me and i fix my program. thanks a-lot
mobin alhassan yes dude, nice, I’m glad you got it fixed!
Awesome Alex.....best part is you always keep maintain energetic and tutorial interesting ...
How do imagines work in java? can you do a video on something like that?
Wow that viedeo really helped me. Thank you very much for that.
Excellent explanation , loved it
Hi Alex, thank you for sharing your understanding plainly. I am trying to get some ideas on Java as I've got to work on the IT field. I would definitely watch other videos from you. Please keep up the good work. I hope I could give you some useful feedback in other videos.
Thanks Alex, u saved me. Was struggling from 1day.😍
4:00 my man's using TWO adblockers
Do exceptions happen during compile time or run time?
I also would like to know this
Master Lee, You are good. Awesome video. Thank you, God bless you
Hi Alex only one suggesstion...if its possible for each topic explain little more, i know it can make begineer confused........but to work in real world project we need little more realstic scenrios.........first video can be basic,2nd video little epth andwith more relastic scenrio...
Really helpful.. u build my concept..
Thankyou
Hii, can someone tell me time stamp for when he starts the tutortial to fix the null pointer exception?
Hello there nice explanation . Tied to create a Generic Array and its not possible unless you are creating an obj from Comparable like T [] = (T []) new Comparable [10] (How is it possible) . T [] = (T []) new Object [] ; also not possible . Class cast exception occurs . Looking for a video from lol . if possible, please upload a video lol. Happy Holidays
Thaank you so much , i really needed this .
Can you make a video on dereferencing null pointer
You can make int method if you create another class and call to the main method
Great teaching, I hope you have a video out on Java working with Apache POI.
Good explanation, thank you
Error 500: java.lang.NullPointerException on mobile please help me
I just spent like an hr writing a program just to get null pointer exception. I hope this helps 🤞
it so helpful thank you so much......
Thank You very much my Nephew.
Thank you Alejandro
Thank you so much bro......
Good content Mr lee
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
brother pls help me how to solve this type error in java
Nice explanation
When do we use null in real life programs?
You are fun and to the point!!
Thank you Alex
best tutorial, thanks a lot!
i cant even get through how to open the java project
im very confused
I've been there hahaha. Create a new project, and import the java file into your project.
Hello Alex, How are you? For the last exemple you do note declare the value of scan does it work if you write the code as below?
System.out.println("Enter your name : ");
Scanner scan = new Scanner(System.in);
scan = null;
System.out.println(scan.netInt());
Have a good day !
ig @r.mwepu
What is that program?
i think i love you :) thanks for the help
bro iam getting error while performing Composition
Show us how to build an app with java
you are the best
i fixed the error thank you so much
Hey! Thanks man!!
can you help me, idont get it
nice example
I love coding thanks to you!
haha yea coding's awesome, you can make anything!
Hi allex, if ur teaching java , can I join you
hello, i have a question, how i solved a possible nullpointer exception of a returnable variable? for example
private int myFunct(){
string number=null;
try{
number = "3"
}catch (Exception e){
e.printStackTrace();
}
return number.toInt32();
}
in this case we are setting a variable who start with a null value , and then we run some code, and that started variable we need to be returned but into an int, that could produce some nullpointer exception right?
java.lang.NullPointerException happens most of the time with old versions of Minecraft.
Thank you!
You saved me bro!
thanks
Just a heads up that you forgot to link this video on the exception video! 😊
u just saved my oop score 😭😭😭
dude cant be much grateful to you
Thanks!!
Your a god dam hero!
Thanks a lot
Thank you :)
You are so good at explaining things...but I still have a question: In what scenarios can null be useful in codes?
Me looking at my wallet
thank you
hi bro , that was a great explain
mahmoud zalik unfortunately, it is hard to fix this problem, but it is in fact possible
The dislikes are from the teachers
thanks bro
