1
00:00:01,420 --> 00:00:06,370
High this is ranked higher than welcome to the next video of this Cartland programming cities.

2
00:00:06,400 --> 00:00:12,300
Now in this video we will learn about Varda do we mean by default functions in case of Cartland.

3
00:00:12,310 --> 00:00:16,930
Now we learn this concept along with the concept of interoperability.

4
00:00:16,960 --> 00:00:23,020
So make sure you have voiced my previous videos then only this video will make sense.

5
00:00:23,020 --> 00:00:27,640
So first of all what do we mean by default arguments in case of functions.

6
00:00:27,640 --> 00:00:33,790
Now suppose I have this Metford name find volume that takes a bit of land and breadth and height and

7
00:00:33,790 --> 00:00:38,020
simply returns the value of the volume of an object.

8
00:00:38,050 --> 00:00:44,630
Right now if you notice here here I have that third bit mean that as height equal to 10.

9
00:00:44,680 --> 00:00:48,650
Now this is actually their default argument in case of Cartland.

10
00:00:48,790 --> 00:00:54,640
So here even if you don't pass the value of height equal to something then also by default the HYGD

11
00:00:54,640 --> 00:00:56,580
will have the value of 10.

12
00:00:57,070 --> 00:00:58,660
So let us take some example.

13
00:00:58,800 --> 00:01:05,890
So here from the main method if all find value method and simply pass the entry as a pyramid that is

14
00:01:06,170 --> 00:01:07,300
Lendell become become.

15
00:01:07,490 --> 00:01:11,560
But it will become three and hide which is by default then right.

16
00:01:11,590 --> 00:01:13,260
So this will simply return.

17
00:01:13,320 --> 00:01:16,140
That is the end of let's say 60.

18
00:01:16,150 --> 00:01:20,710
So in the output we will have to do three into 10 equal to 60.

19
00:01:20,760 --> 00:01:21,610
Right.

20
00:01:22,000 --> 00:01:23,710
And now proceeding forward.

21
00:01:23,740 --> 00:01:29,170
Suppose if I use this method find Vol. 2 3 and 20.

22
00:01:29,170 --> 00:01:32,910
Now if you notice here we are also passing that told it to.

23
00:01:33,220 --> 00:01:35,660
So here Lent will become two.

24
00:01:35,770 --> 00:01:37,190
But it will become three.

25
00:01:37,330 --> 00:01:40,860
And in case of height the value will be overridden.

26
00:01:41,050 --> 00:01:43,650
And this then will now become 20.

27
00:01:43,810 --> 00:01:49,660
So in the output we are going to get two into three into 20 equal to 120.

28
00:01:49,660 --> 00:01:50,470
Right.

29
00:01:50,500 --> 00:01:57,110
So by passing some value here we have simply overridden the void value that is present here.

30
00:01:57,160 --> 00:01:59,270
Then right.

31
00:01:59,380 --> 00:02:03,340
So here inside the intelligent ID this is the same application.

32
00:02:03,370 --> 00:02:07,750
On top of which VVA of working in the previous videos as well.

33
00:02:07,750 --> 00:02:11,320
So here inside the Cartland file I simply create a function.

34
00:02:11,620 --> 00:02:16,620
So here this find volume method simply returns the volume of a particular object.

35
00:02:16,630 --> 00:02:23,170
So inside the main method I would simply use variable reserved equally to find a volume and simply pass.

36
00:02:23,200 --> 00:02:31,600
Let's see two three as Update media now and then simply put in the value of the result.

37
00:02:31,750 --> 00:02:35,470
And now here if you notice here we have to compulsorily bars.

38
00:02:35,510 --> 00:02:37,490
They're told we did no work.

39
00:02:37,500 --> 00:02:42,460
If you don't have the value of the height to pause in their total it metre here.

40
00:02:42,550 --> 00:02:43,060
Right.

41
00:02:43,210 --> 00:02:46,860
So that is why we have their default functions in case of quarterly.

42
00:02:46,990 --> 00:02:53,450
So here Bideford you can give it you can give this height some value let's see 10.

43
00:02:53,590 --> 00:02:56,140
And now here the error will be rectified.

44
00:02:56,590 --> 00:03:03,310
And by passing just two meters we can get the volume of the object right here just because we have their

45
00:03:03,310 --> 00:03:10,030
default value of height as then and then simply then the called by simply clicking on this icon of this

46
00:03:10,030 --> 00:03:13,920
one and simply and then simply run the called.

47
00:03:13,940 --> 00:03:17,220
So here in the output we get 60 right.

48
00:03:17,470 --> 00:03:24,590
And now here suppose if I pause let's say 30 now then we're passing the value of the height then this

49
00:03:24,680 --> 00:03:31,790
value of the height will be older then and this then will be replaced by 30 because the compiler will

50
00:03:31,790 --> 00:03:34,370
give more priority to this value.

51
00:03:34,550 --> 00:03:36,950
And now again let us from the code.

52
00:03:37,310 --> 00:03:40,190
So here we get it in the output.

53
00:03:40,190 --> 00:03:45,650
So this is the advantage of using their default rate meters in case of Cartland.

54
00:03:45,730 --> 00:03:47,860
And now what about the Giago file.

55
00:03:47,980 --> 00:03:51,460
Can we call their default function from our Javal file.

56
00:03:51,460 --> 00:03:53,820
The answer is yes and no boot.

57
00:03:53,980 --> 00:03:55,590
Let's check it out.

58
00:03:55,610 --> 00:04:01,570
Now Java doesn't support their default function if you are a Jaguar developer then you must be aware

59
00:04:01,570 --> 00:04:02,280
of this.

60
00:04:02,290 --> 00:04:06,140
We did not have any concept of default functions in case of Java.

61
00:04:06,370 --> 00:04:12,290
So how can we call their default functions present inside the Cartland file from the job will fail.

62
00:04:12,430 --> 00:04:18,680
So far that we have the A.P. ition of Adoree JVM overlord's.

63
00:04:18,780 --> 00:04:24,450
So this will simply give rise to the interoperability of the java and the Koechlin files.

64
00:04:24,480 --> 00:04:28,230
So inside the indelicacy 80 samples from the java file.

65
00:04:28,350 --> 00:04:35,070
If I tried to call the find value method by simply using this last name my custom girdling filename

66
00:04:36,470 --> 00:04:41,190
my custom girdling finally Dorte find volume and simply buzz.

67
00:04:41,210 --> 00:04:48,430
Let's see food and let's say seven as up if we could so it will simply show some added because the required

68
00:04:48,440 --> 00:04:49,780
argument is three.

69
00:04:49,820 --> 00:04:53,100
And we are only passing the two arguments right.

70
00:04:53,500 --> 00:04:58,280
Just because in Java we don't have any concept of their default function.

71
00:04:58,670 --> 00:05:02,700
So what we can do here is insert my first not guilty.

72
00:05:02,710 --> 00:05:08,720
We can simply use the notation right above defined volume method by using the enervation of our direct

73
00:05:09,200 --> 00:05:11,560
JVM overlords.

74
00:05:11,600 --> 00:05:12,390
Right.

75
00:05:12,590 --> 00:05:17,010
So this will simply make this function compatible with my java file.

76
00:05:17,210 --> 00:05:19,020
Now here the error has gone.

77
00:05:19,130 --> 00:05:23,650
So now you can simply pass to beat meters and simply get that is added.

78
00:05:23,750 --> 00:05:29,070
So I would simply use an that is equal to this one.

79
00:05:29,200 --> 00:05:37,270
And now down the side I will simply print out the value of what is inside our Jabo failed and now to

80
00:05:37,270 --> 00:05:38,120
run the code.

81
00:05:38,170 --> 00:05:47,550
You can simply click on here and then simply then my job will find or mean.

82
00:05:47,740 --> 00:05:53,830
So in the outward record the volume of the object as to it by simply passing two prime readers.

83
00:05:54,050 --> 00:05:57,570
And of course you can pass Treebeard meters as but you will wish.

84
00:05:57,570 --> 00:06:00,730
Let's see what the height is for the bread.

85
00:06:00,770 --> 00:06:03,660
And lent is 7 and 4 respectively.

86
00:06:03,950 --> 00:06:07,520
And now again I read the code by clicking on this icon here.

87
00:06:10,250 --> 00:06:13,690
So here we get some other output of 1 1 2 0.

88
00:06:13,730 --> 00:06:14,760
As it is.

89
00:06:15,050 --> 00:06:17,320
So this was all about their default functions.

90
00:06:17,360 --> 00:06:18,800
And in this video itself.

91
00:06:18,890 --> 00:06:26,450
We also saw how can we call their default function from a particular java file by using the annotation

92
00:06:26,480 --> 00:06:28,980
of our direct JVM overlords.

93
00:06:29,240 --> 00:06:31,010
So see you guys in the next video.

94
00:06:31,010 --> 00:06:31,950
Thanks for watching.

95
00:06:31,970 --> 00:06:33,680
This is considered signing off.
