00:00:00,620 --> 00:00:01,870
Hi this is really at the heart.

2
00:00:01,880 --> 00:00:05,560
Once again welcome to the next beauty of object oriented programming.

3
00:00:05,570 --> 00:00:07,430
In case of Cartland.

4
00:00:07,430 --> 00:00:12,440
Now in this video we will learn about Vaughters inheritance is all about.

5
00:00:12,800 --> 00:00:17,750
But before that let us first understand the properties of the class in case of Codlin.

6
00:00:17,840 --> 00:00:22,190
Now Bideford all the classes in Cartland are public in nature.

7
00:00:22,460 --> 00:00:25,200
And also they are final in nature.

8
00:00:25,430 --> 00:00:26,620
That is Bideford.

9
00:00:26,620 --> 00:00:31,650
You cannot inherit from a particular class to derived class or their suppliers.

10
00:00:31,790 --> 00:00:37,910
So for that the Gore-Clinton provides a special keyword of open keyword to inherit all the properties

11
00:00:37,910 --> 00:00:45,230
of a particular because you have to use the keyboard of open and now for those who are beginners who

12
00:00:45,230 --> 00:00:47,060
don't know what is inheritance.

13
00:00:47,060 --> 00:00:48,720
Please continue with this video.

14
00:00:48,890 --> 00:00:54,410
And for those who know what is inheritance quite well you may skip this review and continue watching

15
00:00:54,410 --> 00:00:56,780
the next video which is there the movie deal.

16
00:00:57,180 --> 00:01:00,530
So let us proceed and check out what is actually inheritance.

17
00:01:00,560 --> 00:01:02,140
In case of Cartland.

18
00:01:02,600 --> 00:01:04,570
So suppose I have here.

19
00:01:04,640 --> 00:01:06,090
Class of dog.

20
00:01:06,320 --> 00:01:08,810
And here I have a class of cat.

21
00:01:08,990 --> 00:01:16,880
Now in case of Class Dog I have some properties such as Gelert breed and some methods such as Bodek

22
00:01:16,890 --> 00:01:17,770
and eat.

23
00:01:18,110 --> 00:01:25,390
Now similarly here in case of glass scared I have the properties of color and age and also some metrics

24
00:01:25,400 --> 00:01:27,530
of meat and eat.

25
00:01:27,590 --> 00:01:34,250
If you compare boot class dog and A-class scared you will find there are some common properties such

26
00:01:34,250 --> 00:01:34,780
as here.

27
00:01:34,790 --> 00:01:36,250
I have color here.

28
00:01:36,260 --> 00:01:37,610
I have color too.

29
00:01:37,720 --> 00:01:39,290
Here I have a function.

30
00:01:39,530 --> 00:01:41,570
And here I have function.

31
00:01:42,140 --> 00:01:45,750
So there is obviously some court repetition in both the classes.

32
00:01:45,800 --> 00:01:48,660
So can we optimize both these classes.

33
00:01:48,860 --> 00:01:52,450
Yes we can with the help of inheritance.

34
00:01:52,490 --> 00:02:00,020
We can simply create a class of animal from which the class carrot and class dog will inherit all the

35
00:02:00,020 --> 00:02:01,070
properties.

36
00:02:01,340 --> 00:02:07,610
So inside the class animal vort will have is I really clear the property of color and also a method

37
00:02:07,610 --> 00:02:08,990
of it.

38
00:02:09,020 --> 00:02:16,970
Now this color and this method is actually present inside the dark plus and also inside the green glass.

39
00:02:16,970 --> 00:02:23,150
So with the help of inheritance we can simply inherit all the properties of animals plus into dog class

40
00:02:23,450 --> 00:02:25,640
and also scared.

41
00:02:25,760 --> 00:02:31,880
So Inglesa Plus dog I will simply modify my code and inherit all the properties from the Animal class

42
00:02:32,000 --> 00:02:35,120
like this class dog clone animal.

43
00:02:35,120 --> 00:02:41,750
Now this is the syntax to inherit all the properties from the class of animal in case of Cartland galloon

44
00:02:41,840 --> 00:02:43,300
followed by animal.

45
00:02:43,400 --> 00:02:46,660
And this is their default primary constructor discoid.

46
00:02:46,770 --> 00:02:47,450
Right.

47
00:02:47,720 --> 00:02:54,440
And in case of it as well we can again use the concept of inheritance galloon space animal.

48
00:02:54,450 --> 00:02:55,040
Right.

49
00:02:55,340 --> 00:03:02,270
And if you notice in case of cat and dog we have simply removed the properties of color and eat function

50
00:03:02,660 --> 00:03:09,620
and now we are only left with the age and myu and here breed and but just because these two properties

51
00:03:09,650 --> 00:03:15,340
are actually present in case of animal that these two pluses are getting indirectly.

52
00:03:15,800 --> 00:03:19,790
So this concept in case of cartilage is known as inheritance.

53
00:03:19,790 --> 00:03:20,460
Right.

54
00:03:20,840 --> 00:03:27,910
And now proceeding forward the classic dog and Glasscock is actually known as the subclass the child

55
00:03:27,920 --> 00:03:30,280
class or their derived class.

56
00:03:30,290 --> 00:03:37,400
Similarly this animal class and this animal class is actually known as the superclass base class or

57
00:03:37,450 --> 00:03:38,680
building blocks.

58
00:03:38,770 --> 00:03:46,440
Right like this and over all we have this animal class which is actually known as the superclass base

59
00:03:46,440 --> 00:03:49,340
class or the parent class right now.

60
00:03:49,620 --> 00:03:54,980
And middle class Bideford inherit from a class of any.

61
00:03:55,010 --> 00:04:00,120
Now this is actually the name of the class that contains few functions.

62
00:04:00,140 --> 00:04:06,380
So in Gotland always remembered every class you would define inside your project has a superclass of

63
00:04:06,620 --> 00:04:14,180
any and this any contains few functions that direct talk about it shortly and now proceeding forward

64
00:04:14,270 --> 00:04:18,490
let us know check out the type of inheritance supported in case of Cartland.

65
00:04:18,680 --> 00:04:24,830
So their type of inheritance is same as the art of Java we have the single inheritance my deliberate

66
00:04:24,860 --> 00:04:28,370
inheritance and also hierarchial inheritance.

67
00:04:28,580 --> 00:04:30,270
So in case of single inheritance.

68
00:04:30,320 --> 00:04:36,340
Suppose I have class B that simply inherits from class.

69
00:04:36,980 --> 00:04:45,200
And in case of midlevel inheritance I have multi-level inheritance such as class C inherits from class

70
00:04:45,230 --> 00:04:49,340
B inherits from class B like this.

71
00:04:49,340 --> 00:04:55,640
Now in case of hierarchial inheritance I have some structure that appears to be like this.

72
00:04:55,640 --> 00:05:02,150
Class B and class the inheritance from plasty and this is the same example that we saw in the previous

73
00:05:02,150 --> 00:05:06,590
slide of dog Gackt an animal and not at the top.

74
00:05:06,590 --> 00:05:11,050
In each of the case we have plasty Plus a and class.

75
00:05:11,300 --> 00:05:17,760
So all these Blassie actually inherit from the any class are the end.

76
00:05:18,120 --> 00:05:24,730
But I so always remember in case of Cartland we have a superclass of any dog.

77
00:05:24,920 --> 00:05:33,260
And now this class B see and here this class B and class C are actually known as their derived class

78
00:05:33,950 --> 00:05:38,360
and this class C which is present here is actually known as the superclass.

79
00:05:38,360 --> 00:05:45,050
Always remember this and now in case my level inheritance we have this Glasby present in between the

80
00:05:45,050 --> 00:05:46,650
class A and class seat.

81
00:05:46,880 --> 00:05:51,300
So for this class C this B is actually acting as a superclass.

82
00:05:51,440 --> 00:06:01,790
But for this class B This B is actually acting as a plus or the child class always remember this again.

83
00:06:01,940 --> 00:06:09,580
Now Varda work class C here we have class B and class A as a superclass for this class C.

84
00:06:09,860 --> 00:06:16,930
So indirectly we are getting all the properties of class B and class C inside plus the.

85
00:06:17,090 --> 00:06:19,930
Because we are having here to make the level inheritance.

86
00:06:20,000 --> 00:06:26,240
So the class present are at the bottom will get all the properties of the classes present ever Big such

87
00:06:26,240 --> 00:06:28,710
as Class B and class C as well.

88
00:06:28,880 --> 00:06:34,840
And along with class any Bideford now word this class and it stands for.

89
00:06:34,910 --> 00:06:42,380
Now this class ne simply contains some before it functions such as equals method hash called mattered

90
00:06:42,730 --> 00:06:44,270
to string method.

91
00:06:44,270 --> 00:06:48,630
Now these methods simply return some value which is boolean in nature.

92
00:06:48,770 --> 00:06:51,230
Integer and string respectively.

93
00:06:51,410 --> 00:06:53,840
And what are the usage of these methods.

94
00:06:53,940 --> 00:07:00,890
We talk about that shortly in our day more video but before that let us define our inheritance in case

95
00:07:00,890 --> 00:07:01,890
of Cartland.

96
00:07:02,150 --> 00:07:09,650
So in case of Gharlane we can define inheritance as it is a mechanism in which an object class acquires

97
00:07:09,800 --> 00:07:12,650
all the properties from experience class.

98
00:07:12,760 --> 00:07:15,640
Right now what does the purpose of inheritance.

99
00:07:15,830 --> 00:07:24,170
So the inheritance simply increases the called re-usability which we saw in this video and it also promotes

100
00:07:24,380 --> 00:07:26,580
dumbwaiter overriding functionality.

101
00:07:26,620 --> 00:07:29,470
Now we have not seen varnas method or writing.

102
00:07:29,470 --> 00:07:33,110
In case of Cartland So we will check it out shortly.
