Which statement is the canonical Java main method signature for the program entry point?

public static void main(String[] args)

private static void main(String[] args)

public static int main(String[] args)

public static void main(String[] args)

Java looks for a method named main with a very specific signature to start a program. The form public static void main(String[] args) satisfies what the runtime needs: it must be accessible from outside the class (public), callable without creating an instance of the class (static), not return any value to the operating system (void), and accept command-line arguments as an array of strings (String[] args). If any part changes—private access, a non-static method, a non-void return type, or a parameter that isn’t String[]—the JVM won’t recognize it as the entry point.

Note that public static void main(String... args) is also valid in practice because varargs is treated as an array of String, but the standard canonical form is public static void main(String[] args).
