Hello world!

  Welcome to java, we have a couple unconventional ways of doing things, but overall I’m like every other mainstream oo language.

  People: AHH! Scary!

  Welcome to python. your knowledge of me wont help you elsewhere as my syntax is purposefully obtuse and unique. Forget about semicolons, one missed space and your code is as worthless as you after learning this language.

  People: Hello based department

    Oh my god I got fucked by a python script once because of a single space. It took forever to figure out what went wrong

      I refuse to code in Python without a really good IDE and linting like PyCharm. When using PyCharm it’s very rare I have issues like this, because it catches them in one way or another, but I notice it catches those kinds of issues a lot when I’m coding soooooooo…

      I have also setup the IDE to specifically color code comments like

      End If

      and

      Next

      in the same style as their beginning statements as I find it much easier to visually scam through code when they are present.

      You can’t use Python without a linter. I have everything setup in vscode to use tabs yet copilot autocomplete insists on inserting random spaces everywhere creating indentation errors. The linter is essential to quickly see and fix them.

    ``**kwargs`

    “No, I don’t use type annotations because they don’t actually do anything. In fact I purposefully give this parameter different types for different behaviors. How is that confusing?”

    Python has its drawbacks but it also has a pretty useful standard library so as a language for small scripts, one can do much worse

    It is possible to dislike both. For me SmallTalk-like languages are peak.

  Python:

  print("Hello world")

    C:

    #include <stdio.h>
    
    int main() {
        printf("Hello World!");
        return(0);

      Python2 is only one character longer:

      print “Hello world!”

        Shell is only meant for duct tape scripts, you know to tie two regular compiled programs together

        source
• JackbyDev@programming.dev ⁨5⁩ ⁨weeks⁩ ago

  This is getting a little better nowadays.

  > cat Hello.java
  void main() {
      System.out.println("Hello, World!");
  }
  > java --enable-preview Hello.java
  Hello, World!
  

  Things to notice:

  1. No compilation step.
  2. No class declaration.
  3. Main method is not public static
  4. No String[] args.

  This still uses preview features though. However, like you demonstrated already, compilation is no longer a required step for simplistic programs like this.

    Microsoft Java is a one-liner these days.

    $ cat program.cs
    Console.WriteLine("Hello, World!");
    $ dotnet run
    Hello, World!

    System.base.stuff.output.out.printfunctions.println

    Or so it felt every time you wanted to dump something into the console…

    Main method is not public static

    It must be somewhere under the hood. Otherwise, it wont be callable and it would require an instance of an object to call. Unless the object here is the Java environment?

    No String[] args

    They are just optional I’m sure, like C and C++. You still need them to read command line arguments.

  I got the impression they skipped the hello world cause it was too easy and they wanted to get right to writing their app so they moved on to more advanced stuff without having a real grasp of the basics
