1

00:00:00,750 --> 00:00:01,680

OK everyone.



2

00:00:01,710 --> 00:00:05,060

Now we want to actually create some text you objects.



3

00:00:05,100 --> 00:00:05,570

OK.



4

00:00:05,730 --> 00:00:09,780

So I'll just paste in some lines of code here and then I'll explain to you what's going on here.



5

00:00:09,780 --> 00:00:10,530

OK.



6

00:00:11,010 --> 00:00:16,390

So as you can see here these are actually the lines of code that actually are pasted here.



7

00:00:16,470 --> 00:00:21,780

And as you can see here first of all we created a text object OK and that and the name of this text



8

00:00:21,930 --> 00:00:25,230

object is to the original values of arii.



9

00:00:25,350 --> 00:00:27,820

And here we are referring to this ID.



10

00:00:27,930 --> 00:00:30,440

OK ATX the original values of.



11

00:00:30,690 --> 00:00:35,640

Again we created another text view object to the values of modified at a.



12

00:00:35,820 --> 00:00:40,850

And here you are referring to the ID TXI the values of modified at a.



13

00:00:41,220 --> 00:00:48,510

And here again we created another takes object takes the modified element and here he referred to this



14

00:00:48,510 --> 00:00:51,900

to this ID TXI the modified element.



15

00:00:51,900 --> 00:00:52,410

OK.



16

00:00:52,650 --> 00:00:58,650

And again we created another takes you object to the original Irais element.



17

00:00:58,770 --> 00:01:04,130

And here we refer to this dx the origin an added element and again we created.



18

00:01:04,140 --> 00:01:10,090

And that takes object to the array element value after Amadi modification.



19

00:01:10,260 --> 00:01:15,570

And here we referred to this ID takes the element value after the modification.



20

00:01:15,570 --> 00:01:16,130

OK.



21

00:01:16,440 --> 00:01:20,290

Now I even try to recreate an array of string values.



22

00:01:20,300 --> 00:01:23,040

Ok so I'm just pasting this at a here.



23

00:01:23,040 --> 00:01:28,360

So as you can see here first of all I specified the data type of my array and then I specify that I



24

00:01:28,450 --> 00:01:34,920

want to actually creating an array by actually putting these brackets here and then I actually gave



25

00:01:35,010 --> 00:01:37,060

a name to my add a string array.



26

00:01:37,170 --> 00:01:40,670

And as you can see here these are the values of my Aure here.



27

00:01:40,680 --> 00:01:41,180

OK.



28

00:01:41,310 --> 00:01:50,100

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z.



29

00:01:50,220 --> 00:01:51,000

OK.



30

00:01:51,330 --> 00:01:57,840

And then I notice that they actually put in a new line character after each value as you can see instead



31

00:01:57,840 --> 00:02:02,400

of double quotes here so that the user can see the values better.



32

00:02:02,400 --> 00:02:02,870

OK.



33

00:02:03,030 --> 00:02:06,030

So now I want to actually create a string object.



34

00:02:06,030 --> 00:02:06,640

OK.



35

00:02:06,810 --> 00:02:14,280

So here as you can see this is my string object and the data type of My object is of type string as



36

00:02:14,280 --> 00:02:15,130

you can see here.



37

00:02:15,390 --> 00:02:18,790

And the name of my object is total original values.



38

00:02:18,960 --> 00:02:23,520

Ok here I actually assigned an empty value to this object here.



39

00:02:23,530 --> 00:02:25,340

Ok to this variable.



40

00:02:25,500 --> 00:02:31,920

And now I want to actually create an enhanced for loop in order to either get over it.



41

00:02:31,920 --> 00:02:35,230

These are values that are actually inside this string array.



42

00:02:35,250 --> 00:02:36,170

Here as you can see.



43

00:02:36,210 --> 00:02:41,130

So here I just pasting these enhanced for loop here and here first about inside the Prentice's of this



44

00:02:41,220 --> 00:02:42,470

enhanced for loop.



45

00:02:42,660 --> 00:02:46,840

I created a string valuable as you can see the type of my value.



46

00:02:46,850 --> 00:02:50,420

But is strange and the name of my variable is value.



47

00:02:50,430 --> 00:02:51,050

OK.



48

00:02:51,240 --> 00:02:57,300

And here I want to actually iterate over the values that are actually inside of this three and three



49

00:02:57,720 --> 00:02:59,400

here as you can see.



50

00:02:59,700 --> 00:03:03,510

And then and then I want to actually do something with those values.



51

00:03:03,510 --> 00:03:08,820

So as you can see here I am I to either iterating over the values that are actually inside of this string



52

00:03:08,850 --> 00:03:09,380

array.



53

00:03:09,630 --> 00:03:13,740

And then here is going to actually assign every one of each values.



54

00:03:13,740 --> 00:03:19,830

For example does the value that is inside of this index 0 of this agree to this value valuable here



55

00:03:19,830 --> 00:03:21,240

to this object the value.



56

00:03:21,510 --> 00:03:27,180

And then here inside of this full loop here if you want to actually first of all we referred to this



57

00:03:27,180 --> 00:03:28,980

total region values.



58

00:03:28,980 --> 00:03:31,070

Object to this really valuable.



59

00:03:31,190 --> 00:03:31,700

OK.



60

00:03:31,920 --> 00:03:33,010

Plus equal.



61

00:03:33,070 --> 00:03:38,070

This line of code is actually the same as this line of code that I am about to write.



62

00:03:38,070 --> 00:03:38,460

OK.



63

00:03:38,460 --> 00:03:41,550

Total all original values OK.



64

00:03:41,610 --> 00:03:42,820

Assignment operator.



65

00:03:42,890 --> 00:03:46,370

Total original values plus value.



66

00:03:46,410 --> 00:03:47,040

OK.



67

00:03:47,040 --> 00:03:53,070

And here in this way as you can see it's going to actually assign the value as you can see for example



68

00:03:53,070 --> 00:03:58,020

at this value that is actually inside of these double quotes and then assign that value to this total



69

00:03:58,020 --> 00:04:01,930

original values variable here that we actually created in line 29.



70

00:04:02,100 --> 00:04:07,290

So after each execution of this for loop after each execution of this enhanced for loop.



71

00:04:07,410 --> 00:04:07,850

OK.



72

00:04:07,950 --> 00:04:15,000

It's going actually to assign the value that is for this specific index of this Aure to this total original



73

00:04:15,000 --> 00:04:18,710

values object that we actually created in line 29.



74

00:04:18,800 --> 00:04:26,060

OK so now we can actually output the value of this total origin and values to the screen.



75

00:04:26,160 --> 00:04:35,210

So I can't just type in the X the original values of a dot set text total original values.



76

00:04:35,430 --> 00:04:38,490

So now let's actually run our project and see what happens.



77

00:04:38,520 --> 00:04:43,160

So as you can see here now we can see these values on this screen here.



78

00:04:43,170 --> 00:04:44,030

OK.



79

00:04:44,040 --> 00:04:46,550

A B C D through that.



80

00:04:46,620 --> 00:04:47,470

OK.



81

00:04:47,880 --> 00:04:51,500

And as you can see here these are the original values of the array.



82

00:04:51,700 --> 00:04:58,800

OK so now let's actually to go back and say this main activity that a file here and after this line



83

00:04:58,800 --> 00:04:59,760

of code here.



84

00:04:59,780 --> 00:05:02,830

Now let's actually add some more lines of code here.



85

00:05:02,990 --> 00:05:07,760

So here I want to actually modify the break.



86

00:05:07,790 --> 00:05:08,360

OK.



87

00:05:08,360 --> 00:05:12,440

You want to modify the values that are actually inside of this houri.



88

00:05:12,440 --> 00:05:15,010

So first of all this actually create a method.



89

00:05:15,200 --> 00:05:15,890

OK.



90

00:05:16,040 --> 00:05:22,860

So just type in here public as you can see here the access modifier of our method is public.



91

00:05:23,520 --> 00:05:29,090

Voyt And again as you can see the return type of Our method is void.



92

00:05:29,090 --> 00:05:30,990

So this method is going to return nothing.



93

00:05:31,070 --> 00:05:35,580

And the name of our method is let's modify the array.



94

00:05:35,720 --> 00:05:36,290

OK.



95

00:05:36,530 --> 00:05:40,760

So here I want to actually specify that this Meffert is going to accept an argument.



96

00:05:40,960 --> 00:05:44,290

OK this is going to accept an argument of type.



97

00:05:44,280 --> 00:05:45,230

Strange.



98

00:05:45,590 --> 00:05:47,700

Actually it is actually an array.



99

00:05:48,020 --> 00:05:53,100

OK an array of string values and the name of this array is for example arey.



100

00:05:53,290 --> 00:05:53,830

OK.



101

00:05:53,960 --> 00:06:00,190

And then we can actually open and close this fit by using these curly braces and inside of the Smurfette



102

00:06:00,200 --> 00:06:03,410

we can actually put our own implementations.



103

00:06:03,410 --> 00:06:07,880

So as you can see here now inside of this Nefert I want to actually put a for loop.



104

00:06:08,200 --> 00:06:08,700

OK.



105

00:06:08,990 --> 00:06:15,470

So this is my full loop here and here as you can see inside of the practices of this for loop.



106

00:06:15,470 --> 00:06:21,610

First of all I created a variable of type integer and the name of this variable is index.



107

00:06:21,800 --> 00:06:25,510

And then I actually assign the values zero to this value.



108

00:06:25,760 --> 00:06:31,490

And here I actually specify the condition OK which determines how many times this group is going to



109

00:06:31,490 --> 00:06:32,270

be executed.



110

00:06:32,300 --> 00:06:35,800

First of all we referred to the name of this variable index.



111

00:06:35,990 --> 00:06:37,780

OK less than Redland.



112

00:06:37,850 --> 00:06:44,270

So this loop is going to be executed until the value of this index variable is less than the value of



113

00:06:44,270 --> 00:06:46,170

the length of this.



114

00:06:46,270 --> 00:06:46,980

OK.



115

00:06:47,240 --> 00:06:54,350

And here as you can see we specified that after each execution of this for a loop the value of this



116

00:06:54,410 --> 00:06:57,490

index variable is going to be incremented by 1.



117

00:06:57,590 --> 00:06:58,240

OK.



118

00:06:58,520 --> 00:07:02,330

So here as you can see inside of these for loop in line 53.



119

00:07:02,330 --> 00:07:05,360

So first of all I referred to the name of this argument array.



120

00:07:05,480 --> 00:07:05,930

OK.



121

00:07:06,070 --> 00:07:07,200

Sup index.



122

00:07:07,400 --> 00:07:10,910

So inside the brackets I referred to the name of this index.



123

00:07:10,910 --> 00:07:11,530

Sorry about that.



124

00:07:11,540 --> 00:07:13,070

As you can see here.



125

00:07:13,070 --> 00:07:16,200

Assignment operator and inside it up quotes.



126

00:07:16,230 --> 00:07:18,660

I just putting a dollar sign.



127

00:07:18,710 --> 00:07:19,010

OK.



128

00:07:19,010 --> 00:07:25,740

Plus So here I want to concatenate disvalue this string value up with another value OK.



129

00:07:25,760 --> 00:07:28,440

Plus Arey sub index.



130

00:07:28,460 --> 00:07:29,080

OK.



131

00:07:29,390 --> 00:07:35,660

So it's going to concatenate this value that is inside of this double quotes with another value that



132

00:07:35,660 --> 00:07:39,080

would be in sight of the specific index of this Aure.



133

00:07:39,230 --> 00:07:44,470

OK so now here let's actually refer to the name of this method here.



134

00:07:44,540 --> 00:07:52,460

Let's modify the Arey So as you know this method is going to actually accept one argument of type String



135

00:07:52,560 --> 00:07:53,180

Theory.



136

00:07:53,210 --> 00:07:58,410

So when you actually give an array of type string to this method.



137

00:07:58,430 --> 00:07:58,890

OK.



138

00:07:59,060 --> 00:08:02,890

So here we have an array of type string called string theory.



139

00:08:02,990 --> 00:08:06,250

So if you can just put it here Strange R.A..



140

00:08:06,980 --> 00:08:11,160

And now let's actually create a string variable.



141

00:08:11,180 --> 00:08:12,710

Ok a string object.



142

00:08:12,740 --> 00:08:14,700

So I just need to put it here.



143

00:08:14,900 --> 00:08:21,890

So as you can see here the Data Type of my variable is strange the name of my variable is total modified



144

00:08:21,890 --> 00:08:23,100

values.



145

00:08:23,110 --> 00:08:28,310

Assignment operator and then I assigned an empty value to this variable OK.



146

00:08:28,490 --> 00:08:30,750

In order to just instantiate this object.



147

00:08:30,770 --> 00:08:31,340

OK.



148

00:08:31,490 --> 00:08:35,810

So now let's actually create an enhanced for loop here.



149

00:08:36,220 --> 00:08:36,810

OK.



150

00:08:37,010 --> 00:08:42,380

And again I can just create a string variable and the name of this value it is value.



151

00:08:42,550 --> 00:08:43,300

OK.



152

00:08:43,920 --> 00:08:44,880

Colon.



153

00:08:45,290 --> 00:08:50,680

And here I can actually iterate over the values that are that are actually inside of these three Aure



154

00:08:51,080 --> 00:08:51,510

here.



155

00:08:51,530 --> 00:08:52,120

OK.



156

00:08:52,580 --> 00:08:57,270

And then I can actually open and close this for a loop by using these curly braces.



157

00:08:57,290 --> 00:09:04,600

So inside of this for loop I can just refer to the name of this valuable total modified values.



158

00:09:04,690 --> 00:09:05,410

OK.



159

00:09:05,870 --> 00:09:10,440

Plus equal value.



160

00:09:11,070 --> 00:09:11,710

OK.



161

00:09:12,730 --> 00:09:18,570

So this line of quote is the same as this line of code that I had to actually write here.



162

00:09:18,790 --> 00:09:25,810

Total multifaith values assignment operator total modified values plus value.



163

00:09:26,190 --> 00:09:26,650

OK.



164

00:09:26,740 --> 00:09:29,430

And then I need to put in a semicolon at the end of my statement.



165

00:09:29,530 --> 00:09:35,580

And now I want to output the value that is inside of this total my default values to the screen.



166

00:09:35,580 --> 00:09:43,720

OK so I can't just take 20 x the values of modified Aure that set text and then I need to refer to the



167

00:09:43,720 --> 00:09:47,060

name of this object total modified values.



168

00:09:47,080 --> 00:09:50,710

And now let's actually run our project and see what happens.



169

00:09:50,710 --> 00:09:57,130

So as you can see here now our application is actually running on this emulator and these are the original



170

00:09:57,130 --> 00:09:58,380

values of the array.



171

00:09:58,440 --> 00:09:58,650

OK.



172

00:09:58,660 --> 00:09:59,410
