Exception in thread “main” java.lang.NoSuchMethodError: main [duplicate]

by

The class containing the main() function must be public, and you may only define one public class per file. You’ll want to have two separate files Risk.java and Territory.java.

Risk.java:

public class Risk {
}

Territory.java:

public class Territory 
{

    public static void main (String[]arg) 
    {
        System.out.println ("hi") ; 
    } 
}

EDIT: It turns out this isn’t true – I was able to run your initial code with the following command line:

java territory

But my earlier comments point to the best practice for a real app, such as a Risk game.
