1

00:00:00,150 --> 00:00:03,030

So let's actually output this value to the like.



2

00:00:03,030 --> 00:00:06,830

So here I can just type in luck that are.



3

00:00:07,020 --> 00:00:15,420

And here I need to actually put into double quotes l o g v the capital letters comma integer numbers



4

00:00:15,750 --> 00:00:22,500

index zero plus two double quotes in order to actually convert this value to our strong values as you



5

00:00:22,500 --> 00:00:28,630

can see here this value here integer numbers index 0 is going to give me of an integer number.



6

00:00:28,710 --> 00:00:32,790

OK so I need to convert that value to a string value.



7

00:00:32,910 --> 00:00:37,840

And here we are saying that give me the value that is inside of the index 0.



8

00:00:37,980 --> 00:00:40,500

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



9

00:00:40,500 --> 00:00:43,910

So as you can see here now our application is actually running.



10

00:00:44,100 --> 00:00:50,520

And here inside is our luck level section choose info and inside of the search bar just type in here



11

00:00:50,580 --> 00:00:52,530

L O G capital letters.



12

00:00:52,530 --> 00:00:52,960

OK.



13

00:00:53,070 --> 00:00:57,870

So as you can see here we have this number 24 here.



14

00:00:57,870 --> 00:01:03,910

So let me actually make this like area wider as you can see this is our number 24.



15

00:01:04,120 --> 00:01:04,540

OK.



16

00:01:04,560 --> 00:01:10,980

So this is the value that is inside of the index zero of these Arey of these integer numbers.



17

00:01:11,010 --> 00:01:12,460

So let me actually.



18

00:01:12,600 --> 00:01:16,280

So then you actually out with the value that is inside of the index one.



19

00:01:16,370 --> 00:01:16,960

OK.



20

00:01:17,100 --> 00:01:19,460

So I just need to type in here like that.



21

00:01:20,320 --> 00:01:27,250

And then to double quotes at O.G. comma integer numbers index for example 1.



22

00:01:27,330 --> 00:01:32,490

Let's let's actually run our project again and here instead of this lark we can't see the values.



23

00:01:32,520 --> 00:01:36,710

So as you can see here it outputted number 0 to the log.



24

00:01:36,750 --> 00:01:37,250

OK.



25

00:01:37,470 --> 00:01:44,320

So now we can understand that the indexes of array by default has half the value zero within them.



26

00:01:44,540 --> 00:01:51,030

OK because we didn't assign any value to the index number of one of these integer numbers it is your



27

00:01:51,030 --> 00:01:51,890

numbers are a.



28

00:01:51,900 --> 00:01:55,890

This index has actually of default value which is zero here.



29

00:01:55,890 --> 00:01:56,830

As you can see here.



30

00:01:56,940 --> 00:01:57,460

OK.



31

00:01:57,720 --> 00:02:03,730

Here let's actually assign a number of value to the index number of one of these are the integer numbers.



32

00:02:03,730 --> 00:02:09,940

Number one assignment operator and here I can actually assign For example number 50.



33

00:02:10,250 --> 00:02:11,040

OK.



34

00:02:11,550 --> 00:02:17,280

And let's actually output this value to the lock lock that i l o g.



35

00:02:17,460 --> 00:02:18,080

Come on.



36

00:02:18,140 --> 00:02:20,820

And it's actually 14 a string value.



37

00:02:20,820 --> 00:02:30,020

This is the value that is inside of the index one of integer numbers.



38

00:02:31,180 --> 00:02:31,720

OK.



39

00:02:31,740 --> 00:02:38,310

So let's actually put a plus operator here and then it's actually fair to the name of this array index



40

00:02:38,310 --> 00:02:39,030

number 1.



41

00:02:39,030 --> 00:02:41,620

So let's actually do it on our project again and see what happens.



42

00:02:41,730 --> 00:02:48,360

So as you can see here in the luck it says this is the value that is inside of the index zero of integer



43

00:02:48,360 --> 00:02:49,850

numbers at a 50.



44

00:02:50,050 --> 00:02:50,930

OK.



45

00:02:50,970 --> 00:02:56,720

So here in line twenty six we assign the number 50 to the index.



46

00:02:56,760 --> 00:03:03,840

One of these aere here of these integer numbers Airey and in line 28 we decided to output that value



47

00:03:03,840 --> 00:03:04,590

to the log.



48

00:03:04,890 --> 00:03:13,050

But in line twenty four when we actually decided to output the value of the index zero of these integer



49

00:03:13,050 --> 00:03:19,650

numbers array here because we didn't actually assign any value to the index of one of these integer



50

00:03:19,650 --> 00:03:23,090

numbers array the default value was 0 0.



51

00:03:23,190 --> 00:03:23,640

OK.



52

00:03:23,760 --> 00:03:31,170

But in 9:26 We assigned to number 52 the index one of these initial numbers array and in line 28 we



53

00:03:31,170 --> 00:03:32,980

can see that by the number 50.



54

00:03:33,110 --> 00:03:33,620

OK.



55

00:03:33,690 --> 00:03:35,010

So hopefully that makes sense.



56

00:03:35,010 --> 00:03:40,590

Let me actually comment out these lines of code here because I want to show you another way of actually



57

00:03:40,590 --> 00:03:45,820

creating arrays in Java at this time it's actually creates an array of strange values.



58

00:03:45,990 --> 00:03:49,820

So first I need to actually refer to the name of this string class.



59

00:03:49,890 --> 00:03:50,320

OK.



60

00:03:50,340 --> 00:03:53,120

First we need to specify the type of R R.



61

00:03:53,130 --> 00:03:53,750

OK.



62

00:03:53,910 --> 00:03:57,160

So we're going to actually have an array of type string.



63

00:03:57,240 --> 00:04:00,240

And then we need to actually flatten a pair of brackets.



64

00:04:00,360 --> 00:04:01,100

OK.



65

00:04:01,590 --> 00:04:06,000

And here we need to actually specify a name for our array.



66

00:04:06,120 --> 00:04:09,560

So for example strange values.



67

00:04:09,930 --> 00:04:10,400

OK.



68

00:04:10,440 --> 00:04:16,400

And here let me actually point out you can actually put these brackets here after this array name.



69

00:04:16,590 --> 00:04:17,120

OK.



70

00:04:17,130 --> 00:04:20,980

It doesn't make any difference if you want to create arrays.



71

00:04:21,420 --> 00:04:25,970

It depends on you if you want to put their brackets after the array name or after.



72

00:04:26,040 --> 00:04:30,150

I personally prefer to put the brackets after the after the type.



73

00:04:30,240 --> 00:04:30,830

OK.



74

00:04:30,990 --> 00:04:35,030

And this is also a preferred way to actually create an array.



75

00:04:35,070 --> 00:04:35,550

OK.



76

00:04:35,610 --> 00:04:42,240

And then it's actually putting an assignment operator after our array name and here instead of just



77

00:04:42,240 --> 00:04:45,490

typing in new strange brackets.



78

00:04:45,510 --> 00:04:51,390

And here we can actually specify the size of what are they for example 20.



79

00:04:51,750 --> 00:04:59,010

OK we can actually write this array we can actually create this array in another way we can put up an



80

00:04:59,010 --> 00:05:05,780

opening brace followed by a closing curly brace and we can hear specific the values of our alley.



81

00:05:05,800 --> 00:05:13,660

Ok for example the value that is inside of the index 0 of this Arev would be for example animal and



82

00:05:13,810 --> 00:05:19,750

the value that is instead of the index of one of this at a would be for example home the value that



83

00:05:19,750 --> 00:05:25,420

is inside of the index number two of these Arev would be for example table.



84

00:05:25,480 --> 00:05:25,820

OK.



85

00:05:25,840 --> 00:05:29,330

And so on and we can actually assign unlimited values to this array.



86

00:05:29,380 --> 00:05:29,840

OK.



87

00:05:29,920 --> 00:05:34,370

In this way you you're actually specifying the values of this array.



88

00:05:34,390 --> 00:05:40,870

You can actually create your array in this way or you can actually create your arrays by using the new



89

00:05:40,870 --> 00:05:47,010

operator and then specify the size of your array and later you can actually assign values to your area.



90

00:05:47,110 --> 00:05:47,500

OK.



91

00:05:47,530 --> 00:05:49,570

As I actually demonstrated that here.



92

00:05:49,590 --> 00:05:53,330

OK here we actually created an array of integer numbers.



93

00:05:53,440 --> 00:05:56,140

And here we are specified the size r r a.



94

00:05:56,410 --> 00:06:01,240

And here we could actually assign some values to the indexes of that Ari.



95

00:06:01,270 --> 00:06:01,790

OK.



96

00:06:02,050 --> 00:06:09,370

But here we are saying that in index 0 puts the value and amount index number of one puts the value



97

00:06:09,370 --> 00:06:13,780

home and in the index number to put a value table.



98

00:06:13,780 --> 00:06:14,250

OK.



99

00:06:14,350 --> 00:06:22,210

And we could actually iterate over the values of this array by just creating a for loop for int.



100

00:06:22,480 --> 00:06:23,140

OK.



101

00:06:23,170 --> 00:06:25,400

Index assignment operator 0.



102

00:06:25,540 --> 00:06:32,710

So I actually created an integer number here an integer value here and I assigned the value 0 to this



103

00:06:33,070 --> 00:06:33,900

variable.



104

00:06:33,910 --> 00:06:34,190

OK.



105

00:06:34,190 --> 00:06:35,400

Index on here.



106

00:06:35,400 --> 00:06:42,400

I need to actually specify a condition until index is less than the values that are inside of this area.



107

00:06:42,610 --> 00:06:46,580

So remember every array in Java knows it's Len.



108

00:06:46,750 --> 00:06:47,160

OK.



109

00:06:47,200 --> 00:06:52,070

So this area as you can see here knows how many values are inside of this array.



110

00:06:52,090 --> 00:06:52,540

OK.



111

00:06:52,600 --> 00:06:58,540

So when you create an array in Java you are actually fairly in place in memory of which that array is



112

00:06:58,540 --> 00:06:59,190

stored.



113

00:06:59,260 --> 00:06:59,760

OK.



114

00:07:00,010 --> 00:07:02,160

So here these are string values.



115

00:07:02,180 --> 00:07:06,880

It is actually referring to a place in memory which these values are actually stored.



116

00:07:06,880 --> 00:07:11,780

So here I can actually refer to the name of this racing values that Len.



117

00:07:11,830 --> 00:07:19,480

So in this way you are actually getting the number of values that are inside of these array.



118

00:07:19,510 --> 00:07:19,970

OK.



119

00:07:20,050 --> 00:07:27,830

And here we can actually take an index plus plus OK and then they can ask you to open and close this



120

00:07:27,880 --> 00:07:32,120

for loop by using these curly braces and inside of this for loop.



121

00:07:32,190 --> 00:07:35,540

We can just type in log dots.



122

00:07:35,940 --> 00:07:37,560

Oh gee come on.



123

00:07:37,650 --> 00:07:42,810

And here first of all we can actually specify the index overlay.



124

00:07:42,810 --> 00:07:56,770

So index number Poulan plus index OK plus and now we can actually specify a value that is inside of



125

00:07:56,770 --> 00:07:57,630

that index.



126

00:07:57,640 --> 00:07:58,370

OK.



127

00:07:58,810 --> 00:08:09,370

So here we can actually typing to double quotes the value that is inside of colon that index colon plus



128

00:08:10,300 --> 00:08:13,040

index plus is plus.



129

00:08:13,060 --> 00:08:17,370

And here let's actually create an line so that you can actually see what's going on here.



130

00:08:17,380 --> 00:08:22,200

String values and it's actually putting a pair of brackets and inside the brackets.



131

00:08:22,200 --> 00:08:29,590

I can actually put it in the index here so I can actually get the value that is inside of that specific



132

00:08:29,620 --> 00:08:30,270

index.



133

00:08:30,310 --> 00:08:32,620

Let's actually run our project and see what happens.



134

00:08:32,620 --> 00:08:35,170

OK everyone as you can see here in the log.



135

00:08:35,470 --> 00:08:38,220

It says index number 0.



136

00:08:38,440 --> 00:08:39,190

Ok ok.



137

00:08:39,200 --> 00:08:43,610

The value that is inside of that index 0 is an amount.



138

00:08:43,750 --> 00:08:44,290

OK.



139

00:08:44,650 --> 00:08:51,240

So here as you can see the value that we put inside of the index zero of these string values array is



140

00:08:51,260 --> 00:08:51,870

Alamein.



141

00:08:51,940 --> 00:08:52,700

OK.



142

00:08:53,080 --> 00:09:00,880

And here it says our index number one the value that is inside of that index one is home.



143

00:09:00,910 --> 00:09:02,560

So this is that value.



144

00:09:02,650 --> 00:09:07,560

And here again it says index number to the value that is inside of that index.



145

00:09:07,570 --> 00:09:11,740

Number two is table and here you can see that's a value.



146

00:09:12,100 --> 00:09:12,790

OK.



147

00:09:13,090 --> 00:09:15,010

So hopefully that makes sense.



148

00:09:15,070 --> 00:09:17,380

And here let me actually show you another important point.



149

00:09:17,410 --> 00:09:21,350

So as you can see here this aere has feet of values inside it.



150

00:09:21,370 --> 00:09:21,840

OK.



151

00:09:21,850 --> 00:09:25,090

This means that the size of this area is free.



152

00:09:25,290 --> 00:09:25,710

OK.



153

00:09:25,750 --> 00:09:31,240

So here if we actually want to output the size of this array through the lock I can just type in luck



154

00:09:31,960 --> 00:09:39,370

that I O G comma and here I can just refer to the name of this area string values that lend plus to



155

00:09:39,370 --> 00:09:43,340

double quotes in order to actually convert this value to a string value.



156

00:09:43,660 --> 00:09:50,100

So now let's actually comment out this for loop so that we can see those values better.



157

00:09:50,140 --> 00:09:54,570

So as you can see here in the log it says LUGG colon free.



158

00:09:54,850 --> 00:09:59,390

And this means that the size of our string values array is free.



159

00:09:59,500 --> 00:09:59,990

OK.



160

00:10:00,160 --> 00:10:01,070

So this array.



161

00:10:01,120 --> 00:10:04,350

So the size of this array is free.



162

00:10:04,510 --> 00:10:08,830

So if we could actually assign only free values to this array.



163

00:10:08,830 --> 00:10:11,980

So let's actually output another value to the.
