Println cannot print nothingness.

You can fix this in one of two ways ...

1)
Change speed() to
public String speed() {
return "30 mph";
}

OR

2)
Change
System.out.println(pet.speed());
to
pet.speed();

Don't do both changes :-)


A note on naming ...
I'd name your existing speed() as printSpeed()
I'd name the revised speed() in (1) as getSpeed()

Designwise, maybe `public int getMPH()` would be better?

Thank you, it chose option 2, it works great.
