This is a well done little introduction. Just a few hours and this is enough knowledge to get some stuff done. You really packed it in here, and yet the pacing doesn’t seem too fast. Good job.

I needed a compact introduction to Java for my OOP class in university. And this was a great fit.
Please, don't forget, that even if the course is in English, the most of the users are not native English speakers and make mistakes too. So I don't expect the instructor to speak Cambridge English either. A big THANK YOU for your effort Alex.
🙏🙂
Thank you!
Thank you very much. I love this full courses covering the basics of a language. :)
Thanks for this effort.
Could you please continue with advanced java, more about OOP and JDBC.
Great course, thanks for this. The comments about stutter and unclear speech are absolutely blown out of proportion. I had no issues whatsoever understanding everything.
Thanks for giving us such a wonderful knowledge
Al fin! lo que esperaba!!!!
I should explain what the 'E' notation represents when dealing with floating point numbers - Think of the 'E' in the minimum values of `float` and `double` in Java as a way to represent really, really small numbers in a more manageable form. It's like using scientific notation you might have learned in school, where you have a number and then "E" followed by an exponent that tells you how many zeros to add (or subtract) to the number.
So, for the minimum values:
- `float` minimum is approximately -3.4028235E38, which means it's an incredibly tiny number, close to zero but with lots of zeros in front.
- `double` minimum is approximately -1.7976931348623157E308, again, an extremely small number but with a huge number of zeros in front of it.
So, the 'E' notation helps us work with these very small values in a more manageable way.
By the way, don't forget to get my full course about Kotlin and Android:

Please could you help us with advanced concepts of java as multi-threading, ...
Awesome! Java was the first programming language I ever learned and I’d like to come back to it. Perfect timing!
I had to learn Java for my data structures course. I already learned C and C++ over a semester and i feel that in this 3.5 hour course i learned more about a programming language than I ever did in a 14 week semester at a university. Thank you very much.
Niceoo Rekap!! 🎉
Java is the first computer language I took a course for, and I was able to get the initial basics, but I quickly got confused when loops were introduced.
I barely made a passing grade, I'll have to give this a watch when I can. I still think about being lost on how to make a working chessboard.
Very helpful, Thanks💯
Loved it when u zoomed in the code ❤cuz it was so small I could not see ,can u keep it that way next time 🙏
Thank you 😊
Why does Eclipse (I have to use it for my Uni course) require a package statement?
The latest LTS (Long Term Support) Version is 21, not 17. You can still use 17. just a helpful note.
Thanks a ton Sir
Amazing!
We are waiting
I was looking for a Java course 👍👏
Plzz use English Subtitles alsoo, It's humble request 🙏🙏
Danke!
didn't know khabib teaches java too! great job!
You may also want to recommend your presenters to use smaller screens or larger fonts. Not everyone will be watching these videos on 34" monitors.
Java the Language
Can I do the tutorial in vscode. If yes, then how, please explain and guide me.
Desktop background is Sri Lanka? I remember that train.
2:24:20 my programme is not working for name and age. What should i do ?
One of my dream in life is learn coding, if not for professional life atleast for self satisfaction.
is IntelliJ no longer free? I'm looking at the download page and there is no longer a black button for free community download. There is only the blue "free-trial" button

Can you guys make a video on Go language basic course for non tech background beginners like me... I wanna learn programming & thinking of starting from Google Go Lang as a first language. Is it okay to learn it first or should I start with something else...
Start with C or Java or Python
They have a long GO video. I think it was just a few months ago, so it should be up do date.
Definitely shouldn’t start with Go, as it is a niche language. Start with Java, C++, Python, or JavaScript-depending on your interests. These are extremely popular. In high demand. And they all have extensive tutorials and documentation available.
Thanks
Crash course but explained in detail
lol
Advanced Data structures and algorithms on Java?🥺🥺🥺
Thank you 🙏🏾🙏🏾🙏🏾🙏🏾🙏🏾 😫
I need that
I wish you had explained what was that 'E' in the min value of floats and double but still a good tutorial especially that accent Mamamia
In Java, the 'E' in the minimum value of `float` and `double` represents the exponent notation used to express very large or very small numbers. It stands for "exponent" and is used in scientific notation.
For example, the minimum value of a `float` is approximately -3.4028235E38, and the minimum value of a `double` is approximately -1.7976931348623157E308.
In these notations, the 'E' is followed by an exponent that indicates the power of 10 by which the value should be multiplied. In the case of the minimum values, the exponents are extremely large and negative, indicating that these numbers are very close to zero but have a magnitude expressed in scientific notation.
@@programmingwithalex.585 yes thank you I get it now
Great sir can you please provide written notes of this course.
are you an Indian?

give us a full advanced course please
There have already did I think

On subtitles so that everyone can understand easily
Why are there so many java introduction videos on this channel and are they any different from each other ?
Can we get an advanced java course with a real time project ?
I still cant figure out how people can learn java with soo many less project videos than nodejs.
Well done
Java is amazing #first
Can we get video how to become a software architect pls
Love from Bangladesh 🥰🥰
At 3:29:49, I had to made the class Vehicule, Car and Plane static to run the program
I love the accent ^^
Yo we all need a SQL course
You have here a course of "SQL for web developers", full course in one video, click on "videos", it's a one month old video. Then, you have a 4 month video, full course-video "SQL Tutorial for beginners" (maybe start from the second, follow with the web specific one...). Then, one year old courses (which for SQL is still absolutely relevant, indeed, much older ones might work , too) of stuff related to SQL (like 3 or 4 more, and surely a lot more, if older), specific courses once you have done at least those two basic courses. I have not watched them, but I'd definitely start from there. Hopefully am not wrong. :D .
This is an *amazing* channel. Good luck and happy learning. :)
@@3polygons thanks a lot dude
@@sanjay2102 yep, no problem. :)
Now it's uploaded you can check out

First view.

i appreciate this dudes perseverance to teach but i cant ignore to notice how bad the way he stutters that it makes it hard for us to understand the procedure
Thanks, dude stuttered way to much though.
damn a russian
Impossible to understand. What's the point? It can rather be a course in his native language, which will still be in demand.
Subtitles have been added
@@soma7891 Oh, boy, you must be kidding. 😂
Eww he’s not using dark mode
can’t understand what u talking, too fast and not clear English , no subtitles.
It's very easy to understand his en English
You didn't expect Alex to be Indian, right?!
No thanks
