Opt out telemetry is annoying. There’s no guarantee it doesn’t send before I’ve had a chance to disable.

Opt out telemetry is annoying. There’s no guarantee it doesn’t send before I’ve had a chance to disable.
Yes, because it’s genuinely not a static method. It’s an instance method. Also the signature is different. It’s not some sort of mere syntactic trick that translates void main()
to public static void main(String[] args)
.
Imagine being so poorly managed that you downsize to cut back on unnecessary spending but literally lose track of an employee. Let’s keep the expense of an employee with none of the revenue generation!
Various languages have various features to make multi threading/concurrent programming easier. Without knowing what language the green text is fanboying for instead of Java it’s hard to know what their specific gripe is. Supporting true multi threading out of the box has always been a priority of Java so I don’t know what they’re complaining about. Generally languages that people praise over Java like Python and JavaScript do not feature true multi threading. (Although Python is getting closer or there now that the GIL is optional.)
I mentioned this uses preview features twice in the first comment regarding this, so I don’t know why you’re "ah ha"ing. Also you don’t need to read the technical document, I’ve quoted the entirety of the relevant text. I provided it as a citation.
You seem confused about preview features. It’s not a switchable mode to reduce boiler plate. I find the name very clear, but here is more information. From JEP-12
A preview feature is a new feature of the Java language, Java Virtual Machine, or Java SE API that is fully specified, fully implemented, and yet impermanent. It is available in a JDK feature release to provoke developer feedback based on real world use; this may lead to it becoming permanent in a future Java SE Platform.
As an example, JDK 17 added pattern matching for switch statements as a preview, and by JDK 21 it was added as a full fledged feature that doesn’t require usage of the enable preview flag. Presumably in some future release of Java this feature will not require the usage of a flag.
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. From JEP-445:
If an unnamed class has an instance main method rather than a static main method then launching it is equivalent to the following, which employs the existing anonymous class declaration construct:
new Object() { // the unnamed class's body }.main();
No String[] args
They are just optional I’m sure, like C and C++. You still need them to read command line arguments.
Without the preview feature enabled, it is not an optional part of the method signature. It specifically looks for a main(String[])
signature.

This is somewhat common for various bugs.
Reminds me of the meme using the Donnie Darko psychologist template.
Donnie: I made a new form of power generation.
Psychologist: New or steam?
Donnie: Steam…

“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?”
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:
public static
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.
You may find JML interesting. https://www.openjml.org/
Java is amazing and I love it, and I agree that this is not really a good list of problems. (Not that I expect green texts to be well thought out, rational, real, fair, or anything other than hyperbolic rants lol.) There are good reasons to critique it and the ways people use it, but this isn’t it.
Particularly funny is the one about race conditions. That’s something you’d have to deal with in any sort of multi threaded environment.
By mathy I mean related to math
This one is probably out of date now with smart TVs and few people using cable, but one of those jumbo TV remotes for people with poor eyesight/motor difficulties.
Spoken like someone who hasn’t had to use both!
I miss that ringtone though.
It’s like email! You know email?
I’ve actually seen this same meme used in the opposite way where they did discover a new way but I don’t remember enough information to find it. And I don’t think it was talking about solar.
