Fully Qualified Class Name

In order to use a public class from a different package you can write out the "fully qualified class name."¹

This is the name of the class prefixed with the package it is in.

package village;

public class Villager {}

package dungeon;

class Dwarf {
    // Works because we write out the full name
    // and because Villager is public.
    village.Villager meet() {
        return new village.Villager();
    }
}

This hints that the "real name" of a class isn't what you write after class, but instead both that and the package name glued together.
