Hey, I live in Mexico and I'm self-studying Java for computer science AP. I just wanted to let you know that even though you have a small channel, you already have international viewers. Vary the channel content a little, post a bit more often, and I'm sure you'll gain a bigger following. You have quality videos and lots of potential. Keep up the good work! :)
Alex, I watched a lot of videos on Java. Frankly speaking, you are doing a great job. Thank you for your time and your praise-worthy efforts! Kind Regards.
Public variables/methods can be accessed from any class or package. Default variables/methods can only be accessed from within the same class or within the same package - a default variable/method cannot be accessed from a class in a different package.
@@hyphen8d725 No unfortunately it's not. With default you can only access within the same package but a protected variable/method can be accessed through inheritance (keyword extends) even from different packages. That's the only difference :)
Thank you for posting this tutorial! I watched other videos of people trying to explain it and it made 0 sense. You really broke it down simplistically. I appreciate it!
love how simply you convey the concepts and often giving real life examples. I know programming concepts can be implemented to any languages, but would love to see some videos with C as well. thanks for the videos man, helped me a lot. all the best, stay safe, stay healthy and happy.
You videos are the reason I am passing my Java class, these videos are clean, easy and your voice recording is amazing. Thanks for creating these videos. Means so much
Thanks man...You make it easy to understand... In the protected class exends part was confusing but at last i read it drom Quora Thanks a lot man... Many Many thanks
I just wanted to thank you for your videos, but honestly...thank you. Words can barely describe how much it helped me starting to learn programming. Your videos are so easy to understand and its short and timesaving. If i learned everything from books, it would have taken me tens or hundreds of hours more!
This was a great intro video to class modifiers. I am starting to understand some of the words I have been blindly typing into my programs. I’d love to see a video with some examples of when these different modifiers are useful.
"So the only difference between default and public is that public you write it in front" - that's not correct. Default fields are only visible to classes in the same package while Public fields are visible to any other class If you leave the access modifier for hours and minutes as 'default' in the class 'Access1', you won't be able to access those fields in the class 'Access3', which is in another package.
Hey Alex you make amazing tutorials I cleared many doubts by watching your tutorials.But I am facing to much problem in array can you make more tutorial on that topic.....
Allover.⬇️ 1. Default. Access within the package only. 2. Public. Access everywhere even outside the package . 3. Private. Access Only in class . 4. Protected. Access in 1 package only but if you use extends keyword then it access in outside the package. But there outside the package Object must be that 2nd package's class
So your are saying at some point(10:20) that default is like public, some other times mentioning that default is accessible just within the same package ...
hey I am from India and use Bluej to study Java, your videos are a great help and i have recommended it to my friends. In Bluej when i use Ctrl-space the triangle or the dot things do not appear and they all are the same. Thanks.
Hey Alex you make amazing tutorials I cleared many doubts by watching your tutorials.But I am facing to much problem in array can you make more tutorial on that topi
I think that you should put most of the videos of this playlist after you talk about oop because you create objects to access classes but havent explained it yet. Anyway good work bud.
Maybe worth mentioning the assignment issues with different access modifiers. E.g at 'protected', you can assign a different value to a variable inside the same package, but while on a extended class - you cant change the value of the original class's variables. I know I explain terrible, maybe Alex can do it better :))
is there a video of how to access the array of object to the main method? p.s. i enjoy watching your tutorial . it is a good help to a person like me as a student.
dice dip hi and thank you! I don’t really know anything about game development so I wouldn’t want to misinform anybody on a topic I don’t know, but I do know java! So I’ll be sticking to java for now :)
@@alexlorenlee Aye no problem!!! Your tutorials are he best I've seen! I've searched the internet for DAYS trying to at least find a program to code in before I saw you! Thank you so much for everything!
Hi there, why is void sometimes used by itself with no access modifiers for e.g. - void fillup(); (which you used in your other video for water bottle) THANK YOU.

Thank you. I enjoy Alex's videos. He is a pro!
Isn't public only accessible in the same CLASS?? and not the file?
Rapport App you mean private?
What pain points do these address. Why do they matter?

Hey, I live in the streets
I live in India
i live in Austria
Go through some Indian java tutorial playlists, you will get some better insights.
Eg. Neso academy
@@A-M-A-N-G I mean, right now I was able to get into the college of my choice here in the U.S. So I'm a little occupied with that.
it seems like every time i have a question, you show up with the answer. Count me subscribed!
I've already watched people from my country for this topic. But I didn't understand them as much as you. Thank you so much, you helped me a lot. :)
Your way of teaching is just exceptional
yeah, I didn't feel it like a boring lecture. it's too simple and easy to know and learn just by watching
Amazing youngest teacher, Amazing personality. I appreciate it bro. Respect you a lot from Azerbaijan.
You helped me with my programming exam last semester. Thank you.
C Cachuela no problem!
Thanks a lot Alex, for everyone the short-cut of System.out.println is type sysout + hit buttons ctrl+space.
You are life saver! my lecturer just gave us the coding and asked us to run the coding to understand on our own :O
Alex, I watched a lot of videos on Java. Frankly speaking, you are doing a great job. Thank you for your time and your praise-worthy efforts! Kind Regards.
this video was sent by my teacher in our google classroom and I think this is great.
You are the best Java tutor who put the idea of Java is not at all hard to learn❤❤
wow man, been searching whole youtube about this from past 2 hrs! i finally got it
Thank you so much
Just wanna let you know that your vids help me out the most when learning java. Thanks!!!
This is the most clear explanation that I saw till date. Thank you very much Alex.
Public variables/methods can be accessed from any class or package.
Default variables/methods can only be accessed from within the same class or within the same package - a default variable/method cannot be accessed from a class in a different package.
So default is basically the same as protected, right?
@@hyphen8d725 No unfortunately it's not. With default you can only access within the same package but a protected variable/method can be accessed through inheritance (keyword extends) even from different packages. That's the only difference :)
@@waschbar4960 oh, I see, thank you!

You are amazing bro! I am currently doing a full stack developer internship with no prior knowledge you are saving me!
Very nicely explained, thank you. I am also glad that you are not using dark mode like others. So much easier to see when it is white background 🙂
after 4 videos and 12 lectures I finally get it thank u
learning basic java again , thanks for making all your videos feel like we're watching blue's clues, you made java look simple.
love how simply you convey the concepts and often giving real life examples. I know programming concepts can be implemented to any languages, but would love to see some videos with C as well. thanks for the videos man, helped me a lot. all the best, stay safe, stay healthy and happy.
I really like your tutorials🥺really help me alot, any topic i was confused I would just search like "interface in java Alex "!!!
You videos are the reason I am passing my Java class, these videos are clean, easy and your voice recording is amazing. Thanks for creating these videos. Means so much
U made the video in a very simple way to understand. Thanks a lot
Hey Alex, Your Videos are really fruitful. Its helping a lot.
Thanks man...You make it easy to understand...
In the protected class exends part was confusing but at last i read it drom Quora
Thanks a lot man...
Many Many thanks
Hi Alex , Awesome tutorial, it helps me lot ..love ❤️ from 🇮🇳
Great video i ever seen on Access Specifiers. You clarified my entire doubts.
Thanks, really appreciate your work!
all the way from Saudi...
Thank you. Very concise and easy to understanding 🎉🎉🎉
I was struggling with this topic. Finally this video helped me. Thanks a lot.

Your explanation was SUPER clear . Thanks a lot
This was a great intro video to class modifiers. I am starting to understand some of the words I have been blindly typing into my programs. I’d love to see a video with some examples of when these different modifiers are useful.
default is only at the same package (not subclasses that are out of the package)
hierarchy:
private -----> default -----> protected -----> public
Huh this was simpler to understand than I expected.
Alex you make coding fun! Please keep on
Hiiii Alex, Tq for your valuable videos. it is really informative to the one who want to learn Java from basics.
Hi Alex, I'm learning Java and I find your videos very educational and enjoyable, I just subscribed, thanks a lot for sharing :)
7:15
Funny how it's usually stated that protected is always confined to a its class/its subclass (irrespective of being of the same package or not)
incredible explanation, very clear and focused. thank you alex!
Thanq for explaining us in simplest way and it makes me more interested to learning java 😍 tq 1ce more
You are a really helpful Java tutor
Superb dude..I like the way of teaching 🙏
This was very helpful. Explained so plainly thank you!
"So the only difference between default and public is that public you write it in front" - that's not correct. Default fields are only visible to classes in the same package while Public fields are visible to any other class
If you leave the access modifier for hours and minutes as 'default' in the class 'Access1', you won't be able to access those fields in the class 'Access3', which is in another package.
He says it at the end
@@Jakeryanu I missed it, so thank you for this. Had to go back.
Yeah, I figured this one out when I tried using the variables in a different package.
Where is your channel?
Hey Alex you make amazing tutorials I cleared many doubts by watching your tutorials.But I am facing to much problem in array can you make more tutorial on that topic.....
Allover.⬇️
1. Default. Access within the package only.
2. Public. Access everywhere even outside the
package .
3. Private. Access Only in class .
4. Protected. Access in 1 package only but if you use
extends keyword then it access in outside the
package.
But there outside the package Object must be that
2nd package's class
What an explanation!🤩
Thanks a lot!
Very concise and easy to understand. Thank you
رائع لقد اجبت بالامتحان بفضلك شكرا لك

thank you. you are great. have a great day
thank you so much Alex, i appreciate you
Best of the best.very easy to understand
I always downvote your videos so I can upvote it two times.
So your are saying at some point(10:20) that default is like public, some other times mentioning that default is accessible just within the same package ...
That was a great vid man. well done you are LEGEND
thank you, bro! you should also make a JavaScript and/or Python course!
Thank you so much for this. Your are AMAZING!!!
A video with examples. Yay!
Hi there! Can you please explain the non-access modifiers as well? Great job so far.
Super helpful! Thanks Alex
very helpful Alex!
you teach really very good
i hope so,you will gain a big no. of followers very soon

Would be useful to add "static" and also show effect on instantiations of the classes Access 1, Access2, Access 3.
