1

00:00:00,810 --> 00:00:05,040

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



2

00:00:05,250 --> 00:00:11,740

So first of all in line 60 the I created a variable of type integer called Aure element.



3

00:00:11,760 --> 00:00:12,610

OK.



4

00:00:13,050 --> 00:00:16,940

And here I actually put in an assignment operator here.



5

00:00:17,160 --> 00:00:20,400

And then I referred to the name of this class.



6

00:00:20,580 --> 00:00:24,960

And here I called this method to this class had on this race class here.



7

00:00:24,960 --> 00:00:25,430

OK.



8

00:00:25,440 --> 00:00:27,810

So ARA is that binary search.



9

00:00:27,900 --> 00:00:30,060

So this river is going to actually return.



10

00:00:30,230 --> 00:00:30,780

OK.



11

00:00:31,000 --> 00:00:37,240

Are specific actually element for that value that we actually specify for this method.



12

00:00:37,260 --> 00:00:38,050

OK.



13

00:00:38,400 --> 00:00:44,270

So this it is going to return a specific element inside of the array that we specify for this method.



14

00:00:44,400 --> 00:00:47,870

So here we refers to the name of these double values array.



15

00:00:47,990 --> 00:00:48,490

OK.



16

00:00:48,660 --> 00:00:54,030

And we want this specific element that actually this value refers to.



17

00:00:54,030 --> 00:00:54,630

OK.



18

00:00:54,930 --> 00:01:00,270

So for example we have and we have these global values right here as you can see.



19

00:01:00,540 --> 00:01:03,960

And this number two point seven as you can see is here.



20

00:01:04,020 --> 00:01:04,540

OK.



21

00:01:04,710 --> 00:01:09,860

We want the specific element the specific index that this value actually first.



22

00:01:09,900 --> 00:01:16,340

OK so now let's actually as you can see here is in line 61.



23

00:01:16,470 --> 00:01:19,640

I actually created an if statement here.



24

00:01:19,730 --> 00:01:20,210

OK.



25

00:01:20,220 --> 00:01:29,430

If the value of this every element is equal is actually greater than or equal to number 0 then the location



26

00:01:29,520 --> 00:01:36,970

of every element that set text and here actually referred to the name of this string class data format.



27

00:01:37,200 --> 00:01:42,580

OK string data formats we've found 2.7 at element.



28

00:01:42,600 --> 00:01:42,990

OK.



29

00:01:43,050 --> 00:01:45,010

Or add index percent.



30

00:01:45,030 --> 00:01:49,860

So this token actually refers to this argument as you can see here.



31

00:01:49,920 --> 00:01:56,310

And this token is actually related to this argument and here as you can see I put a plus operator here



32

00:01:56,310 --> 00:02:00,580

in order to concatenate this value with this value in double values array.



33

00:02:00,990 --> 00:02:03,050

And here I put in a comma here and here.



34

00:02:03,060 --> 00:02:06,950

As you can see I actually put in an argument of type integer OK.



35

00:02:07,170 --> 00:02:11,180

So this token is actually related to this element argument here.



36

00:02:11,270 --> 00:02:12,180

OK.



37

00:02:12,480 --> 00:02:15,990

And then I put in an else statement here else.



38

00:02:16,080 --> 00:02:23,250

So this means if the value of this element is actually less than the value of this zero here else takes



39

00:02:23,250 --> 00:02:28,770

the location of the element that text that said text couldn't find the value in that element.



40

00:02:28,770 --> 00:02:32,710

I think this is Runk couldn't find the value in that houri.



41

00:02:32,790 --> 00:02:37,170

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



42

00:02:37,170 --> 00:02:42,310

So now as you can see our application is running on this emulator here.



43

00:02:42,750 --> 00:02:45,930

And it says the location of our every element here.



44

00:02:45,990 --> 00:02:53,150

We found a number 2.7 at 12:49 one cannot see the other values here.



45

00:02:53,220 --> 00:02:55,620

We can see these are in double values.



46

00:02:55,980 --> 00:02:59,990

So here let's actually go back inside these content underline minute example.



47

00:03:00,000 --> 00:03:08,220

So now here inside of this content underline mean exam and let's actually select our vertical scroll



48

00:03:08,220 --> 00:03:13,720

view here as you can see inside of these containers folder we have a vertical scroll view here.



49

00:03:13,740 --> 00:03:18,730

OK just select this and put it inside this linearly as vertical here.



50

00:03:18,810 --> 00:03:19,610

OK.



51

00:03:20,040 --> 00:03:26,780

And let's actually just select the location element takes view as you can see here and put it's OK to



52

00:03:26,800 --> 00:03:29,980

select it and put it inside this scroll view here.



53

00:03:30,090 --> 00:03:31,360

OK.



54

00:03:31,400 --> 00:03:35,130

Well actually this is a vertical scroll view.



55

00:03:35,140 --> 00:03:39,540

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



56

00:03:39,540 --> 00:03:46,740

So as you can see our application is running on this emulator here and here as you can see it says we



57

00:03:46,740 --> 00:03:51,350

found the number two point seven element 1 in.



58

00:03:51,360 --> 00:03:58,080

So let's actually scroll down here scroll down to scroll view here as you can see I can scroll Now scroll



59

00:03:58,080 --> 00:03:58,720

here.



60

00:03:58,830 --> 00:04:00,210

Now we can see the other values.



61

00:04:00,210 --> 00:04:00,710

OK.



62

00:04:00,900 --> 00:04:06,470

So we found number 2.7 at element 1 in double values.



63

00:04:06,500 --> 00:04:08,370

Ari OK.



64

00:04:08,580 --> 00:04:12,990

So now you may wonder why this value is actually an index.



65

00:04:12,990 --> 00:04:14,870

One of these r.e.



66

00:04:14,940 --> 00:04:15,430

OK.



67

00:04:15,540 --> 00:04:20,320

So as you can see here let's actually go back inside these main activity the Ajo of phi here.



68

00:04:20,340 --> 00:04:23,890

As you can see this number is actually an index.



69

00:04:23,930 --> 00:04:27,920

This is index 0 index one index to inexpertly.



70

00:04:27,990 --> 00:04:30,860

OK so this value is actually an index free.



71

00:04:30,920 --> 00:04:31,910

OK why.



72

00:04:31,920 --> 00:04:36,620

Here it says we found our number 2.7 at element 1.



73

00:04:36,690 --> 00:04:37,000

OK.



74

00:04:37,000 --> 00:04:38,240

Why why this happened.



75

00:04:38,310 --> 00:04:47,970

Because here as you can see in line in line 41 we actually arranged our double values in an ascending



76

00:04:48,000 --> 00:04:48,630

order.



77

00:04:48,630 --> 00:04:49,120

OK.



78

00:04:49,350 --> 00:04:55,110

So here if we actually show you that this is an array of double values here you can see that these values



79

00:04:55,440 --> 00:04:58,300

are arranged in an actually ascending order.



80

00:04:58,350 --> 00:04:58,810

OK.



81

00:04:58,920 --> 00:05:06,150

So here you can see this while you are these numbers 2.7 is actually at index one of these at.



82

00:05:06,190 --> 00:05:15,070

So here as you can see that's why it actually says we found number 2.7 at element 1 in double values



83

00:05:15,090 --> 00:05:15,420

at a.



84

00:05:15,460 --> 00:05:16,690

Ok this is index one.



85

00:05:16,720 --> 00:05:19,090

So hopefully that makes sense.



86

00:05:19,090 --> 00:05:24,070

And I think that's enough for this tutorial.



87

00:05:24,310 --> 00:05:30,580

And if you have any questions please post the discussion in the course and then I'll do my best to answer



88

00:05:30,610 --> 00:05:32,330

all of your questions.



89

00:05:32,320 --> 00:05:36,550

And thank you very much for watching and I'll see you in the next tutorial.
