[DebowyMocny]

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.

[andreasmoor]

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.
🙏🙂

[MarcusHCrawford]

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.

[AliSalem-flfn]

Thanks for this effort.
Could you please continue with advanced java, more about OOP and JDBC.

[maestrogoldring]

Awesome! Java was the first programming language I ever learned and I’d like to come back to it. Perfect timing!

[polygons]

Thank you very much. I love this full courses covering the basics of a language. :)

[oathtone]

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.

[Earth_Being]

One of my dream in life is learn coding, if not for professional life atleast for self satisfaction.

[littlejacob]

Please could you help us with advanced concepts of java as multi-threading, ...

[programmingwithalex.]

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:

[Buharialtinee]

Thanks for giving us such a wonderful knowledge

[jonathanromero]

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.

[codeindia]

Plzz use English Subtitles alsoo, It's humble request 🙏🙏

[bandit]

The latest LTS (Long Term Support) Version is 21, not 17. You can still use 17. just a helpful note.

[aammssaamm]

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.

[mansbjork]

Why does Eclipse (I have to use it for my Uni course) require a package statement?

[Encolas]

Desktop background is Sri Lanka? I remember that train.

[phonecharger]

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 🙏
