This is more or less correct.  Don't forget that the engine is also a 
class, and not an object, until you instantiate the Car, then you have 
both a Car object and an Engine object;

class Car {
   Engine engine = new Engine();
}

There's no objects in the above code until someone calls "new Car()".

Nope, not a darn thing.
