1

00:00:00,750 --> 00:00:06,330

So now inside of these practices of this company and device first of all we need to actually specify



2

00:00:06,330 --> 00:00:07,330

the company name.



3

00:00:07,410 --> 00:00:07,940

OK.



4

00:00:08,010 --> 00:00:14,390

So now I actually paste a piece of code here and then I'll explain to you what's going on here.



5

00:00:15,300 --> 00:00:18,830

So as you can see here this is the company's Arey OK.



6

00:00:18,840 --> 00:00:24,000

Companies inside of the brackets I use specify that index divided by 12.



7

00:00:24,000 --> 00:00:24,610

OK.



8

00:00:24,960 --> 00:00:32,130

So first of all let me tell you that this array is going to be executed until the value of this index



9

00:00:32,130 --> 00:00:39,010

variable here as you can see is less than the value of the line of this company and devices Adli.



10

00:00:39,080 --> 00:00:39,850

OK.



11

00:00:40,140 --> 00:00:45,560

So as you can see here the land of this company and devices array is Sixthly.



12

00:00:45,660 --> 00:00:46,340

OK.



13

00:00:46,620 --> 00:00:54,330

So as you can see here in line 24 where we actually instantiated this array we specified that the size



14

00:00:54,360 --> 00:00:59,360

of this rate is 60 so that the value is the length of this Aure.



15

00:00:59,460 --> 00:01:00,290

OK.



16

00:01:00,600 --> 00:01:07,290

So now for example for the first time that this loop is going to be executed the value of the index



17

00:01:07,290 --> 00:01:08,180

variable is zero.



18

00:01:08,180 --> 00:01:08,770

Okay.



19

00:01:09,000 --> 00:01:12,920

So here we wrote that company and devices sub index.



20

00:01:12,930 --> 00:01:14,630

So the value of the index is zero.



21

00:01:14,790 --> 00:01:19,170

And this means go inside of the index zero of this company and the basis.



22

00:01:19,190 --> 00:01:20,340

Ari Okay.



23

00:01:20,790 --> 00:01:24,340

And now you want to assign a value to that index of that arii.



24

00:01:24,420 --> 00:01:25,010

OK.



25

00:01:25,260 --> 00:01:33,120

So here we just putting the new keyboard here because we want to create some objects of type company



26

00:01:33,120 --> 00:01:37,910

and device class and then we want to assign those objects to this area.



27

00:01:37,920 --> 00:01:38,310

OK.



28

00:01:38,400 --> 00:01:44,390

For example we want to create an object and then we want to assign that object to the index 0.



29

00:01:44,610 --> 00:01:46,110

As you can see here to this area.



30

00:01:46,140 --> 00:01:47,000

OK.



31

00:01:47,400 --> 00:01:54,080

And here in say the practices of this company and devise a class we need to actually specify two arguments.



32

00:01:54,090 --> 00:01:58,690

Ok for the constructor of this class because we are creating an object from this class OK.



33

00:01:58,860 --> 00:02:05,730

So the first argument that we should provide for this constructor is that we need to actually specify



34

00:02:05,730 --> 00:02:06,990

the name of the company.



35

00:02:07,030 --> 00:02:14,250

OK so first of all I referred to the name of these companies here as you can see if we create we created



36

00:02:14,250 --> 00:02:19,910

an array of strings here in line 20 and we assign somebody used to this.



37

00:02:19,970 --> 00:02:20,530

OK.



38

00:02:20,600 --> 00:02:22,890

One two three four five.



39

00:02:22,930 --> 00:02:28,380

We assigned five string values to these at a and b refers to that area.



40

00:02:28,400 --> 00:02:28,840

OK.



41

00:02:28,890 --> 00:02:33,900

And inside the brackets of this Auret I specify that index divided by 12.



42

00:02:33,900 --> 00:02:39,370

OK so the first then that this area is going to be executed the value of this index variable is 0 OK



43

00:02:39,600 --> 00:02:42,150

so zero divided by 12.



44

00:02:42,150 --> 00:02:48,390

So now that we actually opened the calculator app and then I'll show you the calculations that are actually



45

00:02:48,390 --> 00:02:49,890

being performed in this application.



46

00:02:49,890 --> 00:02:50,390

OK.



47

00:02:50,430 --> 00:02:53,500

So as you can see here this is our calculator OK.



48

00:02:53,730 --> 00:02:59,130

So for the first time that this loop is going to be executed the value of this index variable is zero.



49

00:02:59,250 --> 00:02:59,860

OK.



50

00:03:00,030 --> 00:03:06,700

And here inside the brackets of these companies are I to actually divide the value of this index variable.



51

00:03:06,730 --> 00:03:08,040

It is right the number 12.



52

00:03:08,040 --> 00:03:08,510

OK.



53

00:03:08,760 --> 00:03:15,500

So number is 0 divided by number 12 is equal to number 0.



54

00:03:15,500 --> 00:03:15,950

OK.



55

00:03:16,080 --> 00:03:20,460

And then it's going to go inside of the company's array and then it's going to actually go inside of



56

00:03:20,460 --> 00:03:22,110

the index number 0.



57

00:03:22,170 --> 00:03:24,880

OK so as you can see this is the index number 0.



58

00:03:24,880 --> 00:03:25,140

OK.



59

00:03:25,140 --> 00:03:29,630

So remember in proclaiming We always count from number zero.



60

00:03:29,640 --> 00:03:30,680

OK.



61

00:03:31,170 --> 00:03:38,290

So this value of this Apple value is the value that is actually inside of the index zero of these companies.



62

00:03:38,420 --> 00:03:38,970

OK.



63

00:03:39,150 --> 00:03:43,110

So it's going to go inside of these companies are in and then it's going to actually give me this value



64

00:03:43,120 --> 00:03:43,720

apple.



65

00:03:43,920 --> 00:03:44,410

OK.



66

00:03:44,490 --> 00:03:50,460

So this is the first arguments that we actually provided for this company and device constructor.



67

00:03:50,610 --> 00:03:56,310

And the second argument that we should actually provide for this company and the base constructor is



68

00:03:56,520 --> 00:03:58,630

that we need to specify the company device.



69

00:03:58,650 --> 00:03:59,370

Okay.



70

00:03:59,370 --> 00:04:01,280

So this is the company named Apple.



71

00:04:01,770 --> 00:04:04,530

And now I need to actually specify the company device.



72

00:04:04,530 --> 00:04:05,660

So these are the devices.



73

00:04:05,670 --> 00:04:06,270

Okay.



74

00:04:06,570 --> 00:04:13,500

So here I could just refer to the name of these devices are a devices.



75

00:04:13,700 --> 00:04:20,360

And then I could just put in a pair of brackets and this time I want to just type in index.



76

00:04:20,830 --> 00:04:21,360

OK.



77

00:04:21,540 --> 00:04:25,200

Module number 12.



78

00:04:25,610 --> 00:04:30,580

And then I need to actually put in a semicolon at the end of my statement this time I actually referred



79

00:04:30,590 --> 00:04:32,640

to the name of these devices.



80

00:04:32,720 --> 00:04:35,540

Because I want to actually specify the company device.



81

00:04:35,540 --> 00:04:36,170

OK.



82

00:04:36,470 --> 00:04:41,630

And then inside the brackets of these devices array I did a relatively something different.



83

00:04:41,780 --> 00:04:47,740

I actually referred to the name of this index variable module number 12.



84

00:04:47,780 --> 00:04:48,270

OK.



85

00:04:48,410 --> 00:04:55,030

So for the first time that this loop is going to be executed the value of this index variable is zero



86

00:04:55,040 --> 00:04:55,500

OK.



87

00:04:55,670 --> 00:04:59,520

So numbers 0 module number 12.



88

00:04:59,580 --> 00:05:00,050

OK.



89

00:05:00,140 --> 00:05:01,910

Is equal to number 0 OK.



90

00:05:02,030 --> 00:05:03,990

And then it's going to give me the value 0.



91

00:05:04,010 --> 00:05:04,430

OK.



92

00:05:04,520 --> 00:05:08,540

And then it's going to go inside of the index zero of these devices are a.



93

00:05:08,690 --> 00:05:14,800

So the value of this of the index is zero of these devices is experience as it's free.



94

00:05:14,800 --> 00:05:15,270

OK.



95

00:05:15,380 --> 00:05:20,630

And then it's going to return that value to me experience it free and then it's going to actually assign



96

00:05:20,660 --> 00:05:25,530

those values to the index zero of this company and devices at a.



97

00:05:25,680 --> 00:05:26,160

OK.



98

00:05:26,180 --> 00:05:31,910

And then it's going to actually execute this loop until the value of this index variable is actually



99

00:05:31,910 --> 00:05:33,880

less than 60 OK.



100

00:05:33,920 --> 00:05:37,300

Companies and devices that lend is 60.



101

00:05:37,310 --> 00:05:43,330

So for example for the second time that this group is going to be executed the value of the index variable



102

00:05:43,340 --> 00:05:44,120

is number one.



103

00:05:44,120 --> 00:05:44,360

OK.



104

00:05:44,360 --> 00:05:50,420

Because we just specified here that after each execution of this for loop increment the value of this



105

00:05:50,420 --> 00:05:52,270

index valuable by 1.



106

00:05:52,280 --> 00:05:55,600

So now the value of this index variable is number one.



107

00:05:55,610 --> 00:05:56,350

Okay.



108

00:05:56,720 --> 00:06:00,650

And then it's going to actually go inside of this for loop and then it's going to actually execute this



109

00:06:00,650 --> 00:06:02,140

piece of code here.



110

00:06:02,150 --> 00:06:06,300

So first of all we really failed to the name of this Arrey company and devices.



111

00:06:06,320 --> 00:06:07,010

Okay.



112

00:06:07,340 --> 00:06:11,600

And inside the brackets we specify the index of this Aure index.



113

00:06:11,630 --> 00:06:15,680

So now that the value of this index variable is number one.



114

00:06:15,740 --> 00:06:22,330

Now we want to actually assign a value to that specific index to the index number of one of these arii.



115

00:06:22,400 --> 00:06:22,930

OK.



116

00:06:23,030 --> 00:06:30,300

So here I want to actually create an object a new company and device and then first of all for the first



117

00:06:30,620 --> 00:06:35,620

argument of the constructor of this class I need to specify the company name.



118

00:06:35,750 --> 00:06:39,820

So first of all I referred to the name of these companies.



119

00:06:40,380 --> 00:06:40,660

OK.



120

00:06:40,670 --> 00:06:42,860

As you can see here index.



121

00:06:42,860 --> 00:06:48,190

So now as you can see inside the brackets I just referred to the name of this index variable.



122

00:06:48,260 --> 00:06:52,460

So the value of this index variable now is number one.



123

00:06:52,490 --> 00:06:53,140

OK.



124

00:06:53,420 --> 00:06:54,860

Divided by 12.



125

00:06:54,860 --> 00:07:00,260

So number one divided by 12 is number one divided by 12 is number 0.



126

00:07:00,260 --> 00:07:05,750

OK so remember because we are actually divided into two integer numbers it's going to only give us the



127

00:07:05,750 --> 00:07:06,850

value 0 0.



128

00:07:07,010 --> 00:07:09,850

It's going to actually keep this a decimal digits.



129

00:07:09,920 --> 00:07:15,350

And then it's going to only give us the values the 0 because we are actually divided in number an integer



130

00:07:15,350 --> 00:07:17,810

number by another integer number.



131

00:07:17,810 --> 00:07:18,250

OK.



132

00:07:18,290 --> 00:07:21,500

Index divided by 12 is 0.



133

00:07:21,560 --> 00:07:27,090

OK so then it's going to actually go inside of the index zero of these companies Auret.



134

00:07:27,110 --> 00:07:30,900

So the value that is inside of the index zero of these companies right is uphill.



135

00:07:31,010 --> 00:07:32,620

As you can see this value.



136

00:07:33,050 --> 00:07:39,980

And then again here we are actually specifying the company device here for the second argument and then



137

00:07:39,980 --> 00:07:46,200

we go inside of the devices Aure as you can see this is the devices array and then the value of this



138

00:07:46,220 --> 00:07:48,440

index value by now is number one.



139

00:07:48,440 --> 00:07:50,560

So number one module number 12.



140

00:07:50,660 --> 00:07:53,420

So number one module number 12.



141

00:07:54,040 --> 00:07:54,600

Okay.



142

00:07:54,860 --> 00:07:58,820

As you can see number one module number 12 is number 1.



143

00:07:59,150 --> 00:07:59,740

Okay.



144

00:07:59,930 --> 00:08:04,550

And then it's going to go inside of these devices great and then it's going I try to go inside of the



145

00:08:04,550 --> 00:08:07,180

index number of one of these arii.



146

00:08:07,220 --> 00:08:11,930

So the value that is inside of the index number of one of these devices Aure is iPhone 6.



147

00:08:11,930 --> 00:08:12,640

OK.



148

00:08:13,010 --> 00:08:16,320

So then it's going to actually give me this iPhone 6 to me.



149

00:08:16,370 --> 00:08:21,500

And then as you can see it is values the company name and and the company device is going to be assigned



150

00:08:21,680 --> 00:08:25,450

to the index number one of this company and devices arey.



151

00:08:25,490 --> 00:08:26,050

OK.



152

00:08:26,210 --> 00:08:32,240

And for the first time that this is going to be executed again the value of this index value is going



153

00:08:32,240 --> 00:08:33,560

to be incremented by Yvonne.



154

00:08:33,620 --> 00:08:36,410

And now the value of that is inside of the index.



155

00:08:36,440 --> 00:08:39,150

Valuable is actually the number two.



156

00:08:39,280 --> 00:08:41,640

Here instead of the for loop as you can see.



157

00:08:41,690 --> 00:08:44,660

And then it's going to actually check this condition here.



158

00:08:44,660 --> 00:08:47,170

Number two is less than company and devices that lead.



159

00:08:47,270 --> 00:08:51,710

So it is Trudy's condition evaluates to true and then it's going to go inside of this for loop.



160

00:08:51,740 --> 00:08:56,960

And then again it's again it can actually execute this piece of code that is inside of this for a loop.



161

00:08:56,960 --> 00:08:57,760

OK.



162

00:08:57,800 --> 00:09:01,280

So first of all I referred to the name of this company and devices.



163

00:09:01,610 --> 00:09:03,350

OK bracket's index.



164

00:09:03,350 --> 00:09:07,820

So here are now the value of this index value is number two.



165

00:09:07,970 --> 00:09:11,090

So it's going to go inside of the index number two of this array.



166

00:09:11,140 --> 00:09:11,970

OK assignments.



167

00:09:12,050 --> 00:09:16,850

Operator now you want to actually instead assign a value to the index number.



168

00:09:16,860 --> 00:09:18,470

Two of these are.



169

00:09:18,510 --> 00:09:19,380

OK.



170

00:09:19,690 --> 00:09:25,900

A new Ok companion device and now we want to actually create an object from this company and device



171

00:09:25,900 --> 00:09:30,980

class and I want to assign that object to this array through the index number two of that of this address.



172

00:09:31,000 --> 00:09:31,500

OK.



173

00:09:31,510 --> 00:09:36,190

Because we want to actually create an object from this company and device at the constructor of this



174

00:09:36,190 --> 00:09:37,420

class is going to be called.



175

00:09:37,420 --> 00:09:42,910

So if you need to actually specify to actually two values the arguments of this array.



176

00:09:43,000 --> 00:09:47,910

OK we need to actually specify two arguments for this company and device constructor.



177

00:09:47,920 --> 00:09:50,890

And for the first argument we need to specify the company name.



178

00:09:50,890 --> 00:09:51,510

OK.



179

00:09:51,520 --> 00:09:54,630

So as you can see I referred to the name of these companies arii.



180

00:09:54,700 --> 00:09:55,270

OK.



181

00:09:55,600 --> 00:09:56,860

And in brackets.



182

00:09:56,890 --> 00:09:59,050

I just put in brackets here.



183

00:09:59,050 --> 00:10:00,850

Index divided by 12.



184

00:10:00,850 --> 00:10:10,470

Now that the value of this index variable is number 2 so 2 divided by 12 is again number 0.



185

00:10:10,570 --> 00:10:11,060

OK.



186

00:10:11,230 --> 00:10:17,220

So as you can see here because we are actually dividing two integer values together it can actually



187

00:10:17,230 --> 00:10:23,610

only give us an integer number and it can actually skip the the decimal digits.



188

00:10:23,680 --> 00:10:27,910

It's going to only give us an integer numbers divided by 12 is number 0.



189

00:10:27,910 --> 00:10:28,380

OK.
