1
00:00:00,180 --> 00:00:04,019
We need to take a break from applying the big three steps and fix the copy constructor.

2
00:00:07,650 --> 00:00:12,690
So far, we fixed the constructor and we added a geter, the next step should be data center, but there's

3
00:00:12,690 --> 00:00:14,520
something missing in the copy constructor.

4
00:00:14,910 --> 00:00:16,590
So in this lesson, we're going to fix it.

5
00:00:18,840 --> 00:00:21,420
The copy constructor is missing a field update.

6
00:00:23,930 --> 00:00:29,520
We certainly stand to equal to a new object and passed in Nissan as an argument jarvis's the argument

7
00:00:29,540 --> 00:00:31,250
and Nossiter on the copy constructor.

8
00:00:32,400 --> 00:00:38,700
The parameter source story is a reference that points to the Nissan object, this refers to the current

9
00:00:38,700 --> 00:00:43,770
object, the one that's calling the constructor and the copy constructor copies every field from the

10
00:00:43,770 --> 00:00:46,080
source object into the current object.

11
00:00:49,880 --> 00:00:54,830
But wait, it doesn't copy the parts away from the source so that field stays null.

12
00:00:57,720 --> 00:01:02,700
All right, using a raised copy of we're going to set the parts field of the current object being created.

13
00:01:05,560 --> 00:01:07,150
Equal to a copy of the.

14
00:01:08,540 --> 00:01:10,460
Parts away from the source object.

15
00:01:18,240 --> 00:01:20,460
And we're going to copy the full length of the array.

16
00:01:27,140 --> 00:01:30,410
And they're now everything should work, you run your code and test it.

17
00:01:43,810 --> 00:01:48,190
And it works as expected, Nissan 2s parts field, is it not anymore?

18
00:01:50,220 --> 00:01:54,330
The copy constructor copies every value from the source object into the current object.

19
00:02:07,440 --> 00:02:13,890
And now I'm fully confident that every object defines fields and all of these fields have been provided

20
00:02:13,890 --> 00:02:21,090
a value one way or another and finally noticed that both constructors are identical in the first constructor,

21
00:02:21,100 --> 00:02:26,400
we're using parameters to update each field and in the second one, we're updating each field from another

22
00:02:26,400 --> 00:02:27,010
object.

23
00:02:27,360 --> 00:02:29,070
The differences are very minor.

24
00:02:31,660 --> 00:02:37,120
In this lesson, you fixed the copy constructor, each car object has Fifield's, but the copy constructor

25
00:02:37,120 --> 00:02:40,990
was only updating four of them, so we added the extra field updates.
