What are the exact requirements for the `main` method signature in Java?

The `main` method in Java must have the exact signature: `public static void main(String[] args)`. 'public' ensures it can be accessed from anywhere, 'static' means it can be called without creating an object of the class, 'void' indicates it doesn't return any value, and `String[] args` is an array of strings that can be used to pass command-line arguments to the program.
