The main() Method

The main() method is the entry point for standalone Java applications.

To create an application, you write a class definition that includes a main() method.

To execute an application, type java at the command line, followed by the name of the class containing the main() method.

public static void main(String[] args)

The return type must be void.

The main() method must be public.

It is static so that it can be executed without constructing an instance of the application class.
