Public Methods
Even though a class might itself be marked public, the methods
within it will not be unless they are also public.
package village;
// Now other packages will be able to see it
public class Villager {
    public void isVisible() {
        IO.println("This method is callable from another package.");
    }
    void isNotVisible() {
        IO.println("This method is not.")
    }
}
This applies also to static methods.
package village;
public class Well {
    public static int drawWater() {
        IO.println("""
            You need this to be both public and static to
            be able to write Well.drawWater()
            """);
        return 235;
    }
}
