Explain the code if __name__ == "__main__" in terms of the Java language
📁 Advanced Python Topics, question, Beginner
"
I'm new to Python and trying to understand everything through the language I know - Java. When I came across if __name__ == "__main__", I got stuck. I read answers on this topic, but the information still doesn't "click" easily. Is there an analog of this __name__ and "__main__" in Java? Thanks in advance.
P.S. No need to write about duplicates. The questions don't have Java analogs. Don't jump to conclusions. Please read my question carefully.

These constructs cannot be translated to Java individually, but together they can be translated if you understand what they do.
The thing is that in Python, any module is executable - and if you run it, it always gets the name __main__. And __name__ is the name of the current module. Thus, the check if __name__ == "__main__" verifies that the module was run from the command line, not imported from another module.
In other words, the check if __name__ == "__main__" is an additional program entry point.
In Java, the program entry points are main methods:
