    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.

    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:

    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.

    • @programmingwithalex.585
      @programmingwithalex.585 Год назад +1

      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.

    • @3polygons

      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. :)

      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.
