1 00:00:00,360 --> 00:00:02,700 When you write your class, you need to follow three steps. 2 00:00:02,730 --> 00:00:04,320 I call these steps the Big Three. 3 00:00:07,830 --> 00:00:13,950 If a class has fields that needs to have a constructor getters and setters, these are the big three, 4 00:00:14,580 --> 00:00:18,270 it's not an official name, but you need to follow these steps when you write your class. 5 00:00:19,560 --> 00:00:24,990 Right now, your car classes for fields, so it needs one constructor for getters and for setters, 6 00:00:25,680 --> 00:00:27,930 one at a time, we're going to apply these steps.
