1
00:00:01,280 --> 00:00:02,360
This is getting started.

2
00:00:02,370 --> 00:00:06,710
And welcome to the next video of this object oriented programming.

3
00:00:06,810 --> 00:00:11,950
Now so far we have covered almost all topics related to the classes and objects.

4
00:00:12,060 --> 00:00:17,880
Now let us talk about the visibility modifiers in case of Cartland in case of Cartland.

5
00:00:17,970 --> 00:00:25,260
We have the visibility more defiance of public protected internal and private and now in the previous

6
00:00:25,260 --> 00:00:32,960
videos we saw that Bideford all the classes and functions are actually Bideford public in nature.

7
00:00:33,180 --> 00:00:37,000
So in Cortland everything is public in nature by default.

8
00:00:37,020 --> 00:00:38,960
Always remember this.

9
00:00:39,390 --> 00:00:44,370
So here inside the intelligent Id let us explore the visibility more.

10
00:00:44,430 --> 00:00:48,270
Now here I am working under my first daughter Katie file.

11
00:00:48,390 --> 00:00:54,570
So as our top level work classes and functions that I really define here will be by default public in

12
00:00:54,570 --> 00:00:55,320
nature.

13
00:00:55,530 --> 00:01:01,230
As for example here latest example of function trend class person.

14
00:01:01,380 --> 00:01:05,340
So Bideford this function is actually public in nature.

15
00:01:05,430 --> 00:01:05,780
Right.

16
00:01:05,850 --> 00:01:13,340
As we all know from the previous videos and now here this class is again public in nature by default.

17
00:01:13,530 --> 00:01:18,960
Now if you specify here let's see private and also private.

18
00:01:18,960 --> 00:01:25,990
Here then this method and this class person is only visible inside my first dark gate.

19
00:01:26,130 --> 00:01:34,220
Now I suppose if you create one more plus such as let's see new Gorlin file.

20
00:01:34,300 --> 00:01:39,610
See my second so here inside my second Dorte guilty.

21
00:01:39,750 --> 00:01:46,590
These two functions and classes will not be visible just because we have simply declared a private right.

22
00:01:46,710 --> 00:01:48,370
And earlier it was public.

23
00:01:48,390 --> 00:01:55,320
So these two metrics and class can be accessed inside my class Dorte guilty of us public and now in

24
00:01:55,320 --> 00:02:02,970
gardening we have one more mortified of late in doing so if you declared it internal And also this will

25
00:02:03,090 --> 00:02:08,560
as internal then this method and this class will be visible.

26
00:02:08,620 --> 00:02:13,020
Didn't see more do you know what does a Mordy will in case of Coquelin programming.

27
00:02:13,220 --> 00:02:19,040
So if you what is inside the project this Gorlin programming is actually even more D-Will so Amandi

28
00:02:19,040 --> 00:02:25,030
will in case of Cartland programming can be a bunch of Koechlin files or some other files such as a

29
00:02:25,040 --> 00:02:31,940
Mordy will can be intelligent ID Mordy will groovey more D-Will maybe in more detail and so on like

30
00:02:31,940 --> 00:02:32,440
that.

31
00:02:32,630 --> 00:02:38,960
So here if your declared internal So this function and this class will only be visible rigidness seem

32
00:02:38,960 --> 00:02:40,480
more do it right.

33
00:02:40,490 --> 00:02:47,450
So my second thought Guti will have access to this method and also this clus similar to public and now.

34
00:02:47,450 --> 00:02:55,040
Next we have at the end protected and this protected is not applicable for the high level functions

35
00:02:55,070 --> 00:02:56,120
and classes.

36
00:02:56,120 --> 00:03:02,280
So if you declare a function right inside the K-T file then this verdict is not applicable.

37
00:03:02,300 --> 00:03:03,840
So here it shows some error.

38
00:03:03,980 --> 00:03:08,090
The mortified predictor is not applicable at top level function.

39
00:03:08,100 --> 00:03:10,570
Now the same thing applies to the class as well.

40
00:03:10,580 --> 00:03:13,570
This for is not applicable here as well.

41
00:03:13,610 --> 00:03:15,920
So here let us remove it.

42
00:03:15,920 --> 00:03:18,970
And by default we are back to again public.

43
00:03:19,070 --> 00:03:25,280
Now this was all about their top level functions and classes no Valter both inside the class person.

44
00:03:25,280 --> 00:03:32,170
Suppose if I define some variables and functions and also define our derived class then what will happen.

45
00:03:32,180 --> 00:03:38,750
So here I have an open class of person which is actually acting as a superclass for this class of Indian

46
00:03:38,870 --> 00:03:39,800
right here.

47
00:03:39,890 --> 00:03:45,410
Now I suppose if I define private value equal to one inside the class of FERSEN.

48
00:03:45,560 --> 00:03:48,290
So what will happen inside the class of Indian.

49
00:03:48,380 --> 00:03:56,040
So you can not access this variable inside the class of Indian Just because this is private in nature.

50
00:03:56,240 --> 00:03:56,980
So here.

51
00:03:57,080 --> 00:04:04,350
This variable is not visible inside the class of Indian Just because we have marked it as private.

52
00:04:04,550 --> 00:04:08,930
And now let us define predicted value be equal to.

53
00:04:08,930 --> 00:04:12,840
Now here we are using the predicted keyword or the mortified.

54
00:04:12,920 --> 00:04:20,000
So this value of b is actually visible or can be accessed inside the class of Indian just because it

55
00:04:20,000 --> 00:04:21,710
is predicted in nature.

56
00:04:21,920 --> 00:04:26,610
And now next we have internal values C equal to 3.

57
00:04:26,630 --> 00:04:33,940
So since this is internal so again B along with C will be not visible inside the class of Indian.

58
00:04:34,220 --> 00:04:36,930
And now let us go in for the public.

59
00:04:36,930 --> 00:04:41,060
Val be equal to let's see then an asset.

60
00:04:41,100 --> 00:04:46,750
By default all the classes and functions and also the properties are actually public in nature.

61
00:04:46,910 --> 00:04:53,390
So here we don't have to specify this value will be as public explicitly because by default it is public

62
00:04:53,390 --> 00:04:54,140
in nature.

63
00:04:54,260 --> 00:05:02,960
So this value of the is again visible inside the class of Indian doctors we can access it here right

64
00:05:03,530 --> 00:05:03,820
now.

65
00:05:03,830 --> 00:05:08,360
Or do we mean by exactly by visibility of the functions and classes.

66
00:05:08,360 --> 00:05:10,750
Now suppose inside this class Indian.

67
00:05:10,790 --> 00:05:16,310
Suppose if I create a function of let's see test and now insert that test.

68
00:05:16,310 --> 00:05:19,020
Suppose I want to print these values.

69
00:05:19,160 --> 00:05:22,400
So here I would simply use the print function.

70
00:05:22,460 --> 00:05:24,590
Right now inside the print method.

71
00:05:24,590 --> 00:05:26,230
Suppose if I type here.

72
00:05:26,450 --> 00:05:28,850
Let's see the latest beat.

73
00:05:29,240 --> 00:05:36,010
So here the compiler will not show some error because this D can be accessed inside the class of Indian

74
00:05:36,380 --> 00:05:41,990
as it is by default probably known to destroy this value of c latest type.

75
00:05:41,990 --> 00:05:43,690
See no gain.

76
00:05:43,700 --> 00:05:49,820
C is also visible inside the class of Indian because it is internal in nature.

77
00:05:50,740 --> 00:05:55,830
And now let's just talk about this protected be ledes state B.

78
00:05:56,110 --> 00:05:58,480
And here again began to be accessed.

79
00:05:58,480 --> 00:06:06,730
Since it is declared in nature not it has come to the library value of the latest type it here but here

80
00:06:06,730 --> 00:06:10,440
the compiler is not happy because it cannot access a.

81
00:06:10,540 --> 00:06:15,410
It is invisible just because we have MMOG it private in nature.

82
00:06:15,600 --> 00:06:19,900
Right now this was about the superclass and the derived class.

83
00:06:19,990 --> 00:06:27,500
Now what about some other class where we actually define let's say remove this function best and now

84
00:06:27,500 --> 00:06:36,830
he had ordered all let us create one more class of let's see first class and now insert this last it

85
00:06:36,890 --> 00:06:38,260
started to create a method.

86
00:06:38,400 --> 00:06:39,060
Let's see.

87
00:06:39,060 --> 00:06:44,410
Pasting again to test all the visibility of these variables.

88
00:06:44,540 --> 00:06:52,940
Inside this testing method if I created the object of this person let's say value person equal to person

89
00:06:53,270 --> 00:06:56,110
right now inside their testing method that is.

90
00:06:56,130 --> 00:07:00,020
Insert the class that has nothing to do with this class of person.

91
00:07:00,110 --> 00:07:03,440
Let's see how these mortifies plays their key role.

92
00:07:03,620 --> 00:07:05,930
So here inside this let us print.

93
00:07:06,040 --> 00:07:11,200
Let's see if print flares and Dorte the.

94
00:07:11,400 --> 00:07:15,570
So here is now again visible because it is public in nature.

95
00:07:15,570 --> 00:07:17,390
Right now let us try.

96
00:07:17,670 --> 00:07:18,240
Let's see.

97
00:07:18,240 --> 00:07:26,170
See and hear see is also visible because it is internal in nature and the internal variables are always

98
00:07:26,170 --> 00:07:28,170
visible within the same model.

99
00:07:28,360 --> 00:07:31,760
And now let us try B.

100
00:07:31,760 --> 00:07:34,590
Now B is actually predicted in nature.

101
00:07:34,750 --> 00:07:42,970
Now the protected keyword is only applicable to make value visible inside the subclass not in some other

102
00:07:42,970 --> 00:07:43,470
class.

103
00:07:43,500 --> 00:07:43,840
Right.

104
00:07:43,860 --> 00:07:45,780
So always remember this.

105
00:07:45,820 --> 00:07:52,730
The protected keyword will not make your value visible in some other class that has nothing to do with

106
00:07:52,740 --> 00:07:53,360
it.

107
00:07:53,440 --> 00:07:56,420
Now similarly if I use Burreson door.

108
00:07:56,520 --> 00:08:02,790
Then again it is going to show some error that it is favored in nature and we cannot have this value

109
00:08:02,910 --> 00:08:03,950
inside that test.

110
00:08:03,960 --> 00:08:06,120
Plus what I.

111
00:08:06,250 --> 00:08:13,700
So here lately I have some comments for you so here person Doherty and person D'Arby are not visible

112
00:08:13,760 --> 00:08:21,170
because they are private and protected in nature by person C and person or D are actually visible because

113
00:08:21,230 --> 00:08:24,550
they are internal and public in nature.

114
00:08:25,100 --> 00:08:32,000
So I guess no you know what our visibility mortifies in case of Codlin and how it Vashti's in comparison

115
00:08:32,090 --> 00:08:35,290
to some other programming language such as Java.

116
00:08:35,350 --> 00:08:38,670
But I so this is all for this video.

117
00:08:38,780 --> 00:08:40,240
Thank you and have a good day.
