End of an era: Java’s main method is no longer the canonical “bad” syntax example

When was the last time you saw this comparison of why Java syntax is bad:

// HelloWorld.java
public class HelloWorld {
  public static void main(String[] args) {
    System.out.println("Hello World");
  }
}

# hello_world.py
print("Hello World")

With the release of Java 21, you can now do this:

// HelloWorld.java. Run with `java --enable-preview --source 21 HelloWorld.java`
void main() {
  System.out.println("Hello World");
}

BTW, the python example most folks show is almost always wrong. The correct form is actually:

# hello_world.py
def main():
  print("Hello World")

if __name__ == "__main__":
    main()
