1
00:00:01,020 --> 00:00:04,110
A child class can use the constructor of its parent class.

2
00:00:06,480 --> 00:00:10,320
The child class uses its constructor to update its unique fields.

3
00:00:12,080 --> 00:00:16,610
And the child class uses the parent constructor to update inherited fields.

4
00:00:19,550 --> 00:00:23,690
In this lesson, each child class is going to call the parent copy constructor.

5
00:00:27,400 --> 00:00:34,510
So just a quick revision, super refers to the super class, which also means the parent class and super

6
00:00:34,510 --> 00:00:39,790
rich brackets refers to the constructor of the super class, the constructor of the parent class.

7
00:00:40,870 --> 00:00:46,690
If you want to call the the constructor of a parent class, you super an inside person, the object

8
00:00:46,690 --> 00:00:48,220
you want to copy Fields' from.

9
00:00:49,880 --> 00:00:51,750
So inside main, remove the array.

10
00:00:51,800 --> 00:00:54,800
This was just to show you the flexibility of polymorphism.

11
00:01:10,390 --> 00:01:14,410
And now set another object short to equal to a new copy of shirt.

12
00:01:22,610 --> 00:01:26,690
But that's not going to work yet because we're calling it can't be constructive, it doesn't exist.

13
00:01:27,080 --> 00:01:29,960
So here, copy the first instructor, as always.

14
00:01:32,540 --> 00:01:36,410
And instead of getting values from a bunch of different parameters, we're going to get the values from

15
00:01:36,410 --> 00:01:37,550
a source object.

16
00:01:41,770 --> 00:01:44,770
And inside supercapacitor the source object.

17
00:01:51,610 --> 00:01:54,850
Remember, super with brackets means we're calling a constructor.

18
00:01:55,060 --> 00:02:00,550
So this means we're calling the copy constructor of the parent class parent class doesn't have a copy

19
00:02:00,550 --> 00:02:02,560
constructor yet, so we're to have to create one.

20
00:02:03,190 --> 00:02:04,900
So copy the first one, as always.

21
00:02:04,900 --> 00:02:08,770
And instead of getting values from a bunch of different parameters, we're going to get the values from

22
00:02:08,770 --> 00:02:10,810
a source, object, product source.

23
00:02:21,380 --> 00:02:27,710
And once again, notice the polymorphism, the product copy constructor, expect a product object.

24
00:02:28,720 --> 00:02:30,250
But we're passing in a shirt.

25
00:02:33,840 --> 00:02:38,250
Remember that a class can take its own form or it can take the form of the class it's inheriting from,

26
00:02:38,520 --> 00:02:42,000
in this case, the shirt object is taking the form of a product.

27
00:02:46,420 --> 00:02:49,510
All right, put a break point, let's debugged there in time.

28
00:02:50,760 --> 00:02:52,660
Creates a new object of the short class.

29
00:02:52,680 --> 00:02:56,460
OK, this points to the current object that's being created.

30
00:02:57,840 --> 00:03:00,510
Soares points to the object being passed in.

31
00:03:01,720 --> 00:03:05,350
Here are passing the source object into the parent copy constructor.

32
00:03:10,210 --> 00:03:14,800
There it copies the three fields from the source object into the current one.

33
00:03:22,840 --> 00:03:28,570
And once the parent constructor is done, the child constructor copies the last field from the source

34
00:03:28,570 --> 00:03:31,300
object into the current one, beautiful.

35
00:03:38,070 --> 00:03:40,800
And now what if I want to create a copy of Pentz?

36
00:03:42,580 --> 00:03:45,820
So Serpens to equal to a new copy of the pants object.

37
00:03:52,530 --> 00:03:56,500
But that isn't going to work yet because we're calling a copy constructor that doesn't exist.

38
00:03:56,520 --> 00:04:02,910
So here, copy the first constructor and instead of getting values from a bunch of different parameters,

39
00:04:02,910 --> 00:04:05,160
it's going to get the values from a source object.

40
00:04:08,600 --> 00:04:11,510
So inside, superbrain, a person, the source object.

41
00:04:15,060 --> 00:04:15,840
And that's all.

42
00:04:17,620 --> 00:04:18,459
Run the debugger.

43
00:04:25,570 --> 00:04:29,860
It creates a new object of the pants class, the instructor receives a source object.

44
00:04:33,930 --> 00:04:39,750
Here we're passing the source objecting to the parent copy constructor there, it copies three fields

45
00:04:39,750 --> 00:04:41,790
from the source object into the current one.

46
00:04:47,940 --> 00:04:53,550
And once the parent constructor is done, the child constructor copies of the last field from the source

47
00:04:53,550 --> 00:04:55,080
object into the current one.

48
00:05:04,930 --> 00:05:08,710
Let's recap a child class, can you do the copy constructor of its parent class?

49
00:05:09,960 --> 00:05:15,960
The child uses the parent copy constructor to update inherited fields, and it can use its copy constructor

50
00:05:15,960 --> 00:05:17,580
to update its unique fields.
