Does it really? I had no idea. Mea culpa. Still, we could have used
the command being invoked to run the class.

Thinking about this some more, the class is not public (it's default
package-private, I think.) And it's not in any package either. So
without testing to see if two classes at in the default package can
reference each other, and with out any changes (no static main) to the
original, this would work:

public class Runner {
    public static main( String [] args ) {
        MortPayCalc2 morty = new MortPayCalc2();
        morty.main( args );
    }
}

Certainly, if you put both these classes in the same file, it would
work. (Well, and the file was called Runner.java.)

Which may explain how your class was expecting to be used. It's a
slightly different idiom than the ones we were giving you.
