* possToys.add(toCheck);

* }

* return possToys;

* }

* QUESTION 2: The Motor Company

*

* Part A

* public class Car

* {

* //instance variables

* private String itsType; // couple, sedan, wagon

* {

* int count = 0;

* for(int i = 0; i<carsProduced.size(); i++)

* {

* Car curCar = (Car)carsProduced.get(i);
