1 00:00:00,480 --> 00:00:05,060 This solution, we're going to inspect the store class and see if we can throw some exceptions, the 2 00:00:05,070 --> 00:00:08,590 constructor doesn't receive any parameters, so nothing to check here. 3 00:00:09,210 --> 00:00:14,100 There is nothing a quality control in the center, because if the user happens to pass a null, it would 4 00:00:14,100 --> 00:00:15,780 already throw a null pointer exception. 5 00:00:16,410 --> 00:00:17,600 And that's really it. 6 00:00:17,610 --> 00:00:23,040 I can't really think of a scenario where we would need to throw an illegal argument, exception or even 7 00:00:23,040 --> 00:00:27,120 an illegal state exception so we can just leave the class the way it is. 8 00:00:27,120 --> 00:00:29,730 And I'll see you in part eight.
