1
00:00:00,580 --> 00:00:02,860
This time, we're going to the center before the geter.

2
00:00:06,160 --> 00:00:10,150
The array field contains no values, so right now there's nothing to really get.

3
00:00:12,730 --> 00:00:15,760
So in this lesson, we're going to add a letter that updates the cars field.

4
00:00:19,250 --> 00:00:24,590
The dealership has one field, so we need to add one setar, I told you before that a seller starts

5
00:00:24,590 --> 00:00:26,490
with the word set and ends with the full name.

6
00:00:27,050 --> 00:00:29,800
So should our set to be called set cars?

7
00:00:30,320 --> 00:00:34,340
No, said cars implies updating every object at once.

8
00:00:34,340 --> 00:00:35,760
And that doesn't make any sense.

9
00:00:36,140 --> 00:00:39,100
Currently, the car's array only has room for three cars.

10
00:00:39,530 --> 00:00:45,290
But what if we made room for one hundred cars or a thousand cars and you only want to update one of

11
00:00:45,290 --> 00:00:45,480
them?

12
00:00:46,160 --> 00:00:51,230
Surely you're not going to pass in an array of a thousand objects for the sake of updating one?

13
00:00:52,340 --> 00:00:54,020
The screaming cat doesn't approve.

14
00:01:04,550 --> 00:01:09,770
The senator should update one object at a time and let the user choose which one.

15
00:01:10,800 --> 00:01:12,890
This approach offers more flexibility.

16
00:01:17,380 --> 00:01:20,140
So when your dealership class at the Sutter said car.

17
00:01:27,430 --> 00:01:30,040
And it's going to take one car object as a parameter.

18
00:01:32,310 --> 00:01:37,830
All right, now our dealership object can call set car and when called set car is going to receive a

19
00:01:37,830 --> 00:01:38,670
car object.

20
00:01:39,480 --> 00:01:45,540
But which index in the car, Zoraida, we add it to we need to add another parameter that takes an index

21
00:01:45,540 --> 00:01:47,220
value int index.

22
00:01:52,050 --> 00:01:56,940
And at the index chosen by the user, we're going to set that element in the car's array.

23
00:01:59,720 --> 00:02:01,790
Equal to a new car object.

24
00:02:04,940 --> 00:02:08,570
And we're going to call the copy constructor by passing in a source object.

25
00:02:10,710 --> 00:02:15,420
Also, notice that I'm setting the area equal to a copy of the car object, and I'm not just setting

26
00:02:15,420 --> 00:02:16,410
them equal to each other.

27
00:02:16,830 --> 00:02:19,460
You don't want your field to get caught in the reference trap.

28
00:02:19,500 --> 00:02:24,000
Get in the habit of creating a new object and using the copy constructor to copy every value from a

29
00:02:24,000 --> 00:02:24,540
source.

30
00:02:25,050 --> 00:02:30,300
Right after we're creating a new car object, we're passing in a source object down the nose to run

31
00:02:30,300 --> 00:02:32,730
the copy constructor that receives one as a parameter.

32
00:02:33,030 --> 00:02:37,440
And then it's going to copy every field value from the source object into the one we just created.

33
00:02:38,070 --> 00:02:42,720
And remember that this refers to the current object that's called the A constructor or method.

34
00:02:45,480 --> 00:02:50,100
All right, now we can update the cars right in Maine, we're going to update the first index in the

35
00:02:50,100 --> 00:02:54,120
cars field with the Nissan Object dealership that said car.

36
00:02:55,410 --> 00:02:56,150
Nissan.

37
00:02:58,640 --> 00:02:59,750
At Index zero.

38
00:03:03,650 --> 00:03:06,350
And now update index one with the Dodge object.

39
00:03:12,040 --> 00:03:14,200
And indexed to what, the second Nissan?

40
00:03:26,830 --> 00:03:29,350
And they're now your dealership has three cars.

41
00:03:35,840 --> 00:03:41,030
First, you're setting the element at index zero equal to a new car object, and after creating the

42
00:03:41,030 --> 00:03:43,030
new object, you're passing in a source.

43
00:03:43,400 --> 00:03:48,260
So have a nose to run the copy constructor, which copies every field from the source object into the

44
00:03:48,260 --> 00:03:49,160
current object.

45
00:03:50,450 --> 00:03:52,300
You did the same thing for index one and two.

46
00:04:07,870 --> 00:04:09,760
And now your dealership is full of cars.

47
00:04:11,430 --> 00:04:16,410
Now, before we wrap up, you can clean up our code a little, instead of defining three separate car

48
00:04:16,410 --> 00:04:18,990
variables, we can define an array of cars.

49
00:04:21,040 --> 00:04:21,700
Currys.

50
00:04:23,610 --> 00:04:26,220
Is equal to a new array of car objects.

51
00:04:32,370 --> 00:04:36,300
The first element in the array is a car object with fields that describe a Nissan.

52
00:04:46,300 --> 00:04:51,130
The second element in the array is going to be another car object with fields that describe a dodge.

53
00:04:52,650 --> 00:04:57,210
And the third element of the car object is also going to be a Nissan, but with a color of yellow.

54
00:05:05,500 --> 00:05:07,000
And a new set of parts.

55
00:05:20,630 --> 00:05:22,310
Also, by the way, this.

56
00:05:24,510 --> 00:05:26,190
Is the same thing, is this.

57
00:05:27,780 --> 00:05:31,020
And you know what, we can also pass this array directly.

58
00:05:52,320 --> 00:05:55,050
And now we can pass in the car object at index zero.

59
00:06:00,040 --> 00:06:01,090
Index one.

60
00:06:01,950 --> 00:06:02,880
An index to.

61
00:06:03,880 --> 00:06:08,560
And now you might be wondering, isn't there a better way to do this and you would be right to assume

62
00:06:08,560 --> 00:06:14,260
so instead of writing the same code three times a week can create a far loop that runs through the length

63
00:06:14,260 --> 00:06:15,100
of the car's array.

64
00:06:15,880 --> 00:06:20,650
By the way, since you're familiar with loops at this point, I don't mind showing you a trick to autocomplete

65
00:06:20,650 --> 00:06:21,150
A for loop.

66
00:06:21,550 --> 00:06:22,960
Just click on Fawry.

67
00:06:26,810 --> 00:06:31,940
And what this does is it creates a loop that runs through the length of the nearest Thouret, pretty

68
00:06:31,940 --> 00:06:32,600
convenient.

69
00:06:33,170 --> 00:06:36,620
I didn't want to show it to you before just because I wanted you to practice creating loops.

70
00:06:36,620 --> 00:06:38,480
But right now, I know you're an expert.

71
00:06:39,610 --> 00:06:42,730
Anyways, during each run, we're going to call a set car.

72
00:06:44,190 --> 00:06:50,010
And we're going to index a car object and pass it in as the first argument and in the second argument

73
00:06:50,010 --> 00:06:52,500
pass in the index, that's it.

74
00:06:59,550 --> 00:07:04,170
Ultimately, the Sloup is going to update the cars filled with car objects, that index is zero one

75
00:07:04,170 --> 00:07:04,590
and two.

76
00:07:07,250 --> 00:07:08,880
In this lesson, you added a Seder.

77
00:07:08,930 --> 00:07:15,170
The Seder set car receives two values, an object and an index, and then it updates the array at an

78
00:07:15,170 --> 00:07:16,460
index of your choice.

79
00:07:18,730 --> 00:07:22,390
You updated index zero of the cars field with the Nissan object.

80
00:07:26,150 --> 00:07:27,530
One would dodge.

81
00:07:33,570 --> 00:07:35,700
And indexed to what, the second Nissan?
