00:00:00,730 --> 00:00:05,930
Hiding the strings in the heart and welcome to the next video of the concept of inheritance in this

2
00:00:05,930 --> 00:00:10,910
video we will check out their demo for the concept of inheritance in Cartland.

3
00:00:10,910 --> 00:00:13,210
So here insert the intelligent ID.

4
00:00:13,240 --> 00:00:16,680
I've simply defined some code just to save time.

5
00:00:16,730 --> 00:00:20,370
So here I have class or dog inside the class dog.

6
00:00:20,450 --> 00:00:23,010
I have some properties of color and breed.

7
00:00:23,180 --> 00:00:25,150
Both are of their type of string.

8
00:00:25,510 --> 00:00:28,610
And I have some function of bark and eat.

9
00:00:28,610 --> 00:00:36,080
Now down the side I have another class of Gackt that contains the properties of color and age and also

10
00:00:36,080 --> 00:00:39,450
the functions of meal and eat right.

11
00:00:39,800 --> 00:00:48,890
Now if you compare both the class here we have variable color and function eat and here as well I have

12
00:00:49,190 --> 00:00:51,700
variable color and function.

13
00:00:51,950 --> 00:00:56,350
So don't you think the courts are redundant and they need to be optimized.

14
00:00:56,360 --> 00:01:00,490
The answer is yes we can optimize the code here as well.

15
00:01:00,590 --> 00:01:01,870
So how to do it.

16
00:01:01,910 --> 00:01:05,350
So here comes the concept of inheritance in the picture.

17
00:01:05,720 --> 00:01:10,640
So both cat and dog are actually animal like we all humans are.

18
00:01:10,790 --> 00:01:18,290
So here I would simply create a class of let's say animal and now inside this I would simply define

19
00:01:18,650 --> 00:01:22,120
this variable colored simply.

20
00:01:23,550 --> 00:01:29,720
And pasted inside the class of animal and then simply go the function of it from here.

21
00:01:30,480 --> 00:01:38,160
And then we stayed inside the class of animal and now simply removed the white space he had as well.

22
00:01:38,310 --> 00:01:44,980
And now inside the guard let us remove the VAT colored and also remove this function.

23
00:01:45,010 --> 00:01:47,260
Eat.

24
00:01:47,370 --> 00:01:51,360
So here we will apply the concept of inheritance in case of dog.

25
00:01:51,590 --> 00:01:53,890
So fair play inheritance in Gears of Cartland.

26
00:01:54,080 --> 00:01:59,380
We will use galloon space animal right now here.

27
00:01:59,400 --> 00:02:00,710
It will show some error.

28
00:02:00,740 --> 00:02:02,200
Let me tell you about Izard.

29
00:02:02,210 --> 00:02:10,280
Similarly in case of cat as well I will simply use Golon space animal now in the previous video we talked

30
00:02:10,280 --> 00:02:13,420
about the property of a class such as Bideford.

31
00:02:13,420 --> 00:02:16,020
The classes are public and final.

32
00:02:16,100 --> 00:02:21,860
So by default you can not inherit the properties of a class and to apply the concept of inheritance.

33
00:02:21,950 --> 00:02:25,010
You have to use the keyboard of open.

34
00:02:25,090 --> 00:02:30,700
So here Bideford Vortiger class and functions are variables that you would define in case of Cartland

35
00:02:31,180 --> 00:02:35,050
are actually public and final in nature.

36
00:02:35,110 --> 00:02:35,800
Right.

37
00:02:35,860 --> 00:02:42,790
So here it shows that these two are actually redundant because Bideford every class is public and every

38
00:02:42,790 --> 00:02:44,300
class is final.

39
00:02:44,320 --> 00:02:51,280
Now the same applies to this very well as well which is again public in nature by Bideford and also

40
00:02:51,280 --> 00:02:53,350
final in nature by default.

41
00:02:53,410 --> 00:02:59,740
So you need not to specify it explicitly because this is their default behavior in Gotland.

42
00:02:59,800 --> 00:03:02,470
So let us remove it here now.

43
00:03:02,560 --> 00:03:08,930
Same thing applies to this class animal as well where this class is actually public and final.

44
00:03:09,010 --> 00:03:16,000
So that is why the compiler will simply throw an error that this animal is actually public and final

45
00:03:16,000 --> 00:03:17,650
and cannot be inherited.

46
00:03:17,890 --> 00:03:23,500
So by default when you want to inherit some properties in case of Cartland you have to make a class

47
00:03:23,590 --> 00:03:26,460
open by using the open keyword.

48
00:03:26,470 --> 00:03:32,370
Now as soon as you declare open so this class is now no longer final in nature.

49
00:03:33,220 --> 00:03:36,100
And this class can be inherited in case of dog.

50
00:03:36,100 --> 00:03:40,900
And also in case of cat and now Lexi what is it again.

51
00:03:40,930 --> 00:03:45,140
So here it says that the animal has to be a type of constructor.

52
00:03:45,340 --> 00:03:48,450
So here I would simply use a constructor sign.

53
00:03:48,640 --> 00:03:50,500
And now the error has gone.

54
00:03:50,500 --> 00:03:54,740
And similarly in case of ladies use a constructor sign.

55
00:03:55,030 --> 00:03:57,220
And now again the error has gone.

56
00:03:57,220 --> 00:04:05,180
So let us move inside the main method and here I will simply declare that dog equal to Lerche C dog.

57
00:04:05,410 --> 00:04:08,050
So this was simply clear the object of their dog.

58
00:04:08,350 --> 00:04:18,000
Now I can simply use dog dog breed equal to let's see Lambro and similarly dog.

59
00:04:18,120 --> 00:04:26,870
Let's see color equal to let's say black and now Similarly I can simply call the method such as dog

60
00:04:26,920 --> 00:04:36,280
Darbar and also dog dog eat but I now notice here that this dog dark color is actually the part of class

61
00:04:36,370 --> 00:04:40,620
animal that we have inherited inside the class of dog.

62
00:04:40,690 --> 00:04:46,810
And similarly then we call these dog dog eat method then it is simply calling the method present inside

63
00:04:46,810 --> 00:04:47,700
the animal.

64
00:04:47,720 --> 00:04:51,580
Plus now the same thing will apply for the cat object.

65
00:04:51,610 --> 00:04:53,960
So let us define the cat object.

66
00:04:54,100 --> 00:05:00,970
So here as well we are calling God dark colored dark simply points to this color very well present inside

67
00:05:00,970 --> 00:05:02,290
the Animal class.

68
00:05:02,500 --> 00:05:04,060
And similarly Gagg dog.

69
00:05:04,090 --> 00:05:10,130
It simply triggers this method in the Animal class and now at the end Cephalus.

70
00:05:10,150 --> 00:05:17,130
If I create that espies animal equal to animal Let's see what happens.

71
00:05:17,860 --> 00:05:21,150
And then if I use animal dot operator.

72
00:05:21,250 --> 00:05:28,270
So here you will find only two options color equal to let's see white by different animals.

73
00:05:28,290 --> 00:05:28,730
Right.

74
00:05:28,780 --> 00:05:29,450
Let's see.

75
00:05:29,530 --> 00:05:35,600
Let's call it white animal or dog let's see eat and now apart from colored and eat.

76
00:05:35,680 --> 00:05:41,890
You don't have any properties inside the animal class because this animal is actually their top level

77
00:05:41,890 --> 00:05:45,290
class that does not inherit from any other class.

78
00:05:45,310 --> 00:05:46,320
Right.

79
00:05:46,360 --> 00:05:51,940
So in this video we learn the basics of how do we apply inheritance in case of Cartland.

80
00:05:52,330 --> 00:05:57,800
And now if you run the code then these methods will be called and you will get some output in the output

81
00:05:57,860 --> 00:06:02,430
console such as eat bark and meal something like that.

82
00:06:02,440 --> 00:06:07,870
So in this video we learn the basics of how do we apply the inheritance in case of Cartland.

83
00:06:08,050 --> 00:06:13,410
And now there are a lot more things that need to be discussed from the next video onwards.

84
00:06:13,570 --> 00:06:15,640
So let's check it out in the next review.
