1

00:00:00,440 --> 00:00:05,620

Hire everyone in this theater here I'm going to talk about comparisons OK.



2

00:00:05,880 --> 00:00:08,650

So first we need to create a Java project.



3

00:00:08,790 --> 00:00:13,740

So just click on this find new and then click on Java project.



4

00:00:13,740 --> 00:00:14,580

OK.



5

00:00:14,640 --> 00:00:17,450

So for the project name just type in here.



6

00:00:17,730 --> 00:00:18,600

Comparison's



7

00:00:21,410 --> 00:00:22,160

OK.



8

00:00:22,420 --> 00:00:24,050

And click on finish.



9

00:00:24,250 --> 00:00:27,560

So as you can see here our project is now created.



10

00:00:27,790 --> 00:00:30,520

So we need a class for our project.



11

00:00:30,550 --> 00:00:38,720

So just click on this as our See folder and then click on File new and click on class.



12

00:00:38,740 --> 00:00:39,700

OK.



13

00:00:40,300 --> 00:00:44,780

So for the class name just type in here comparison.



14

00:00:46,560 --> 00:00:49,230

And for the package name we need it.



15

00:00:49,240 --> 00:00:54,160

The worst domain here you just type in here com dot your name.



16

00:00:54,340 --> 00:00:54,960

OK.



17

00:00:55,150 --> 00:00:59,670

And at the end of your package name just put that project name.



18

00:00:59,680 --> 00:01:00,790

OK comparison's



19

00:01:05,330 --> 00:01:06,610

for the modifiers.



20

00:01:06,740 --> 00:01:07,680

Choose public.



21

00:01:07,730 --> 00:01:12,940

And make sure that you take the check box here that says public static void main effort.



22

00:01:12,950 --> 00:01:13,620

OK.



23

00:01:13,790 --> 00:01:17,880

This is going to be our starting point for running our Java code.



24

00:01:17,900 --> 00:01:18,540

OK.



25

00:01:18,710 --> 00:01:20,200

And then click on finish.



26

00:01:20,450 --> 00:01:23,400

So as you can see here our class is now created.



27

00:01:23,570 --> 00:01:26,250

So first let me actually it's this comment here.



28

00:01:26,450 --> 00:01:32,340

So in order to make this a little area of Vider you need to actually double click on this comparison



29

00:01:32,360 --> 00:01:33,550

Dutch over top here.



30

00:01:33,620 --> 00:01:36,860

And as you can see this entire area is now much wider.



31

00:01:36,860 --> 00:01:37,810

OK.



32

00:01:37,880 --> 00:01:44,570

And in order to make this a little area smaller You just need to actually double click and these are



33

00:01:44,570 --> 00:01:46,190

comparisons that Jobar had here.



34

00:01:46,190 --> 00:01:47,030

OK.



35

00:01:47,300 --> 00:01:50,940

So now I want to actually write some code here.



36

00:01:51,020 --> 00:01:51,560

OK.



37

00:01:51,590 --> 00:01:55,130

So as you know I want to talk about comparisons.



38

00:01:55,160 --> 00:02:03,740

Java has several operators for making any comparisons and variables variables and literals or other



39

00:02:03,740 --> 00:02:05,950

types of information in a program.



40

00:02:06,000 --> 00:02:13,570

OK these operators are used in expressions that return boolean values of true or false.



41

00:02:13,610 --> 00:02:19,180

Ok so now let me actually show you some real examples in order to make this concept more clear for you.



42

00:02:19,190 --> 00:02:19,640

OK.



43

00:02:19,700 --> 00:02:25,740

Now I want to create some variables here the data type of my variable is boolean.



44

00:02:26,120 --> 00:02:28,360

The name of my variable is.



45

00:02:28,370 --> 00:02:31,790

For example if you want.



46

00:02:32,900 --> 00:02:35,390

And then I assign a value to my variable.



47

00:02:35,480 --> 00:02:36,330

False.



48

00:02:36,580 --> 00:02:37,090

OK.



49

00:02:37,190 --> 00:02:40,410

So at the end of your statement you need to put in a semi-colon.



50

00:02:40,440 --> 00:02:41,010

OK.



51

00:02:41,240 --> 00:02:48,710

And I want to create another variable here in the name of my value is 8 and I want to assign a value



52

00:02:48,710 --> 00:02:49,320

to my.



53

00:02:49,400 --> 00:02:51,090

For example 25.



54

00:02:51,170 --> 00:02:53,940

So now I want to actually make a comparison here.



55

00:02:53,990 --> 00:02:58,420

So I just need to refer to the name of my boolean variable.



56

00:02:58,610 --> 00:02:59,610

Is.



57

00:03:00,130 --> 00:03:01,110

OK.



58

00:03:01,490 --> 00:03:09,200

And then I just type in here h less than 50 and then at the end of my statement I need to put in a semi-colon



59

00:03:09,200 --> 00:03:09,860

OK.



60

00:03:10,250 --> 00:03:19,450

So first let me actually output the value of these variables to the console system that out that princeling.



61

00:03:19,940 --> 00:03:25,550

And then inside Apprentice's I just need to refer to the name of my variable is young and at the end



62

00:03:25,550 --> 00:03:28,190

of my statement I need to put in a semicolon.



63

00:03:28,460 --> 00:03:36,890

And here again I want to actually output the value of this h variable to the console system that's out



64

00:03:37,040 --> 00:03:39,200

that princeling.



65

00:03:39,890 --> 00:03:44,660

And then inside Apprentice's I need to refer to the name of my valuable which is age.



66

00:03:44,660 --> 00:03:45,190

OK.



67

00:03:45,320 --> 00:03:50,290

And here I want to output the value of this easy and variable to the console.



68

00:03:50,290 --> 00:03:50,690

OK.



69

00:03:50,810 --> 00:03:59,600

So a system that out that print to learn and then inside Apprentice's I just need to refer to the name



70

00:03:59,600 --> 00:04:01,370

of my Yahn qualia.



71

00:04:01,400 --> 00:04:02,700

OK.



72

00:04:03,650 --> 00:04:06,740

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



73

00:04:07,130 --> 00:04:15,190

So if you are on my project now as you can see it's going to actually output these values to the console



74

00:04:15,190 --> 00:04:15,800

OK.



75

00:04:16,040 --> 00:04:17,990

So the first value is false.



76

00:04:18,080 --> 00:04:18,360

OK.



77

00:04:18,380 --> 00:04:23,080

As you can see I assigned the false value to my boolean variable here.



78

00:04:23,090 --> 00:04:23,700

OK.



79

00:04:23,900 --> 00:04:31,690

And in line 14 I decided to output the value of this variable to the concert which is false OK in line



80

00:04:31,700 --> 00:04:32,640

16.



81

00:04:32,650 --> 00:04:40,850

Are you declared the age variable and I assigned the value 25 to my variable and in line 17 I decided



82

00:04:40,850 --> 00:04:44,570

to output the value of this age variable to the cops.



83

00:04:44,600 --> 00:04:45,120

OK.



84

00:04:45,290 --> 00:04:47,610

As you can see here which is 25.



85

00:04:47,630 --> 00:04:48,260

OK.



86

00:04:48,470 --> 00:04:54,810

As you can see I assigned another value to my is the variable here.



87

00:04:54,980 --> 00:04:55,420

OK.



88

00:04:55,460 --> 00:05:03,140

So the value of this variable here is and comparison expression and this expression produces a result



89

00:05:03,230 --> 00:05:08,120

of either true or false depending on the value of the integer h.



90

00:05:08,140 --> 00:05:13,730

OK because age is 25 OK and age is less than 50.



91

00:05:13,730 --> 00:05:14,280

OK.



92

00:05:14,450 --> 00:05:21,440

And this expression evaluates to true and that true value is assigned to this isn't valuable.



93

00:05:21,560 --> 00:05:28,850

So if I run on my project as you can see this is the value of this is the variable that is out to the



94

00:05:28,850 --> 00:05:29,810

console OK.



95

00:05:29,840 --> 00:05:32,540

So that they actually show you some other examples.



96

00:05:32,870 --> 00:05:35,620

So let me comment out these lines of code here.



97

00:05:35,630 --> 00:05:38,370

So now let me actually create some other variables here.



98

00:05:38,420 --> 00:05:46,390

For example the Data Type of my variable is Boullion and the name of my variable is is powerful.



99

00:05:46,730 --> 00:05:49,730

And then I assign a value to my variable here.



100

00:05:49,820 --> 00:05:50,980

For example fart's.



101

00:05:51,000 --> 00:05:51,590

OK.



102

00:05:51,800 --> 00:05:55,600

And then at the end of my statement I need to put in a semi-colon OK.



103

00:05:55,790 --> 00:06:02,500

So if I output the value of this variable to the console system that out that line and then inside the



104

00:06:02,670 --> 00:06:08,940

prentices refer to the name of my valuable so here I want to put some text here.



105

00:06:09,120 --> 00:06:17,750

This is the value of the is powerful valuable.



106

00:06:17,820 --> 00:06:18,660

OK.



107

00:06:19,020 --> 00:06:22,710

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



108

00:06:23,070 --> 00:06:29,230

So if I run my project now as you can see it's going to actually output this value to the consumer.



109

00:06:29,370 --> 00:06:35,850

So I forgot to actually put the variable name inside it practices so I use that plus operator here in



110

00:06:35,850 --> 00:06:39,190

order to concatenate this text with my variable name.



111

00:06:39,380 --> 00:06:39,980

OK.



112

00:06:40,070 --> 00:06:41,490

Is powerful.



113

00:06:41,640 --> 00:06:42,180

OK.



114

00:06:42,360 --> 00:06:47,920

And here I actually create a space here in order to make this readable.



115

00:06:48,360 --> 00:06:53,490

So if I run my project as you can see it outputs this value to the console.



116

00:06:53,490 --> 00:06:57,250

This is the value of that is powerful variable fots.



117

00:06:57,380 --> 00:06:58,030

OK.



118

00:06:58,200 --> 00:07:03,320

So I assigned the false value to my is powerful value.



119

00:07:03,330 --> 00:07:06,320

OK so now you want to create another variable.



120

00:07:06,480 --> 00:07:12,310

So for example the data type of my variable is it and the name of my variable is energy



121

00:07:15,180 --> 00:07:15,780

OK.



122

00:07:16,050 --> 00:07:18,150

And then I assign a value to my variable.



123

00:07:18,150 --> 00:07:24,110

For example 57 and then at the end of my statement I need to put in a semicolon.



124

00:07:24,420 --> 00:07:30,750

So here I want to output the value of this variable to the console system that out of that peninsula.



125

00:07:31,920 --> 00:07:37,530

And then inside Apprentice's I just need to refer to the name of my variable and at the end of my statement



126

00:07:37,590 --> 00:07:39,560

I need to put an assembly code on OK.



127

00:07:39,870 --> 00:07:44,520

So if I run my project as you can see it's going to output this value to the console.



128

00:07:44,520 --> 00:07:52,620

OK so let me actually put the text here just put into double quotes and inside the double quotes just



129

00:07:52,770 --> 00:07:53,700

type in your text.



130

00:07:53,700 --> 00:08:01,770

For example this is the value of the energy variable



131

00:08:06,900 --> 00:08:07,520

OK.



132

00:08:07,940 --> 00:08:12,410

And create a space here in order to make this value more readable.



133

00:08:12,460 --> 00:08:18,160

OK so if I run my project now as you can see it's now showing an error.



134

00:08:18,170 --> 00:08:19,520

OK.



135

00:08:19,520 --> 00:08:26,420

So as you can see here I forgot to actually put the plus operator in between these two values.



136

00:08:26,450 --> 00:08:26,980

OK.



137

00:08:27,050 --> 00:08:33,680

If you don't put this A-plus OPERATOR You cannot concatenate text and variables together.



138

00:08:33,680 --> 00:08:34,430

OK.



139

00:08:34,670 --> 00:08:40,850

So if you are on my project now as you can see it outputs this value to the console.



140

00:08:40,890 --> 00:08:43,860

OK this is the value of the energy value of it.



141

00:08:43,880 --> 00:08:44,390

OK.



142

00:08:44,450 --> 00:08:45,970

Which is 57.



143

00:08:46,100 --> 00:08:46,680

OK.



144

00:08:47,120 --> 00:08:50,650

So now I want to actually make a comparison here.



145

00:08:50,720 --> 00:08:53,340

So I need to refer to the name of the boolean value.



146

00:08:53,360 --> 00:08:55,750

Here is powerful.



147

00:08:55,900 --> 00:08:56,300

OK.



148

00:08:56,330 --> 00:08:58,960

And then I assign a value to my variable.



149

00:08:59,030 --> 00:09:01,890

And so I want to actually create an expression here.



150

00:09:02,030 --> 00:09:06,360

So energy greater than 80.



151

00:09:06,790 --> 00:09:07,270

OK.



152

00:09:07,340 --> 00:09:10,790

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



153

00:09:11,060 --> 00:09:13,630

So as you can see here it's now showing me an error here.



154

00:09:13,640 --> 00:09:17,990

Let's actually how there are mouse pointer over the error area.



155

00:09:17,990 --> 00:09:23,240

So let's actually hover our mouse pointer over the error area and see what's this error.



156

00:09:23,240 --> 00:09:28,040

So as you can see I didn't write my variable name correctly.



157

00:09:28,040 --> 00:09:28,680

OK.



158

00:09:28,950 --> 00:09:33,380

And I need to actually put the letter E here.



159

00:09:33,590 --> 00:09:35,180

So now the error is gone.



160

00:09:35,300 --> 00:09:38,330

OK so now I want to output the value of.



161

00:09:38,330 --> 00:09:41,410

This is powerful variable to the console.



162

00:09:41,540 --> 00:09:49,130

So I just need to type in here system that out that printed on and then inside the prentices I just



163

00:09:49,130 --> 00:09:52,770

need to refer to the name of my variable is powerful.



164

00:09:52,880 --> 00:09:56,050

And then at the end of my statement I need to put in a semi-colon.



165

00:09:56,060 --> 00:09:56,380

OK.
