 * - Q4: What happends if you try to use am enhanced for loop?
 *
 * - A: The original doors will not be replace. When you use for (Door door :
 * doors), JVM will copy the value to door (or copy the address). If you set
 * door = new Door(), the new door will be assigned to that copied object,
 * istead of the object in array.
