1

00:00:01,020 --> 00:00:03,180

So hopefully that makes sense.



2

00:00:03,210 --> 00:00:05,820

Now let's actually create another method here.



3

00:00:06,120 --> 00:00:06,780

OK.



4

00:00:06,780 --> 00:00:09,650

So here I'm going to paste this method here.



5

00:00:09,840 --> 00:00:12,860

And then I'm going to actually explain to you what's going on here.



6

00:00:12,870 --> 00:00:13,620

OK.



7

00:00:13,740 --> 00:00:15,720

So as you can see here this is my method.



8

00:00:15,820 --> 00:00:17,670

They are actually pasted here.



9

00:00:18,120 --> 00:00:21,650

And the access modifier of this method is public.



10

00:00:21,810 --> 00:00:24,690

The return type of this method is in integer.



11

00:00:24,690 --> 00:00:31,680

So this method is going to return a value of type integer and the name of this method is calculate the



12

00:00:31,680 --> 00:00:34,140

overall power of animal.



13

00:00:34,190 --> 00:00:34,830

OK.



14

00:00:34,980 --> 00:00:39,450

And here you can see inside of this method I am returning an integer value.



15

00:00:39,550 --> 00:00:44,650

OK so here I am referring to the name of this good animal power method.



16

00:00:44,700 --> 00:00:50,010

So as you can see here this is our Get Alamein our power and foot here and this method actually returns



17

00:00:50,010 --> 00:00:51,800

the value of the animal power.



18

00:00:51,920 --> 00:00:52,540

OK.



19

00:00:52,920 --> 00:01:01,320

Here I notice that I didn't actually directly referred to the name of these animal power instance variable



20

00:01:01,560 --> 00:01:05,460

because in this way my codes are actually more professional.



21

00:01:05,610 --> 00:01:11,990

And this is the most this is actually the best way to write your code so we always refer to your guitars



22

00:01:12,270 --> 00:01:15,960

in order to access the value of those instance variables.



23

00:01:15,960 --> 00:01:16,880

OK.



24

00:01:17,010 --> 00:01:23,730

And here I am referring to the name of this get my power effect multiplied by the value of this or get



25

00:01:23,810 --> 00:01:27,450

any more speed or method as you can see this is the case any more speed.



26

00:01:27,450 --> 00:01:28,290

OK.



27

00:01:28,950 --> 00:01:37,470

And now let's actually overwrite the twisting method that we actually implicitly inherit from the Object



28

00:01:37,470 --> 00:01:37,810

class.



29

00:01:37,830 --> 00:01:38,030

OK.



30

00:01:38,040 --> 00:01:46,590

So remember all all of the classes in Java actually implicitly or explicitly inherit all of the features



31

00:01:46,650 --> 00:01:49,560

and behaviors that are inside of the Object class.



32

00:01:49,580 --> 00:01:54,770

OK so now we can actually override the two string method.



33

00:01:54,860 --> 00:01:55,200

OK.



34

00:01:55,200 --> 00:02:01,920

So I just need to take to and press ENTER key here as you can see I am overwriting the twisting method



35

00:02:02,220 --> 00:02:04,340

that is actually inside of the Object class.



36

00:02:04,340 --> 00:02:04,790

OK.



37

00:02:04,890 --> 00:02:07,400

And here as you can see it says Return superior.



38

00:02:07,440 --> 00:02:12,630

The two string it's going to actually executes the implementation instead of these two string may fit



39

00:02:12,650 --> 00:02:15,670

inside the inside of the superclass.



40

00:02:15,690 --> 00:02:16,150

OK.



41

00:02:16,290 --> 00:02:17,130

Object class.



42

00:02:17,310 --> 00:02:19,410

So I don't need this implementation.



43

00:02:19,410 --> 00:02:23,940

I want to actually put in my own implementations inside of these two string Meffert.



44

00:02:24,060 --> 00:02:30,030

So I can't just delete this line of code here and inside of this method I can actually put in my own



45

00:02:30,030 --> 00:02:30,990

implementations.



46

00:02:31,000 --> 00:02:37,020

OK so here inside of this Peppard I want to actually paste in some lines of code and then I'll explain



47

00:02:37,020 --> 00:02:38,400

to you what's going on here.



48

00:02:38,550 --> 00:02:39,170

OK.



49

00:02:39,750 --> 00:02:44,100

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



50

00:02:44,550 --> 00:02:47,360

And here you can see I am actually returning right here.



51

00:02:47,610 --> 00:02:48,890

String format.



52

00:02:48,940 --> 00:02:49,270

OK.



53

00:02:49,280 --> 00:02:52,980

It's actually this effort as you can see this format may fit that.



54

00:02:52,980 --> 00:02:58,710

I am actually calling on the string class is going to return up stream object.



55

00:02:58,710 --> 00:03:00,330

OK a string value.



56

00:03:00,330 --> 00:03:04,620

So return string format here instead of these double quotes.



57

00:03:04,620 --> 00:03:08,240

I am actually specifying the format of my string value.



58

00:03:08,240 --> 00:03:08,550

OK.



59

00:03:08,540 --> 00:03:09,050

Percent.



60

00:03:09,050 --> 00:03:19,860

As Kallen percent as percent and our percent is Colan space person as person and person as colon as



61

00:03:19,860 --> 00:03:25,400

you can see here spaced person D is for actually integer values integer arguments.



62

00:03:25,500 --> 00:03:29,140

Percent and is actually up a newline character.



63

00:03:29,240 --> 00:03:29,880

OK.



64

00:03:29,930 --> 00:03:32,540

Percent as call and space percent.



65

00:03:32,640 --> 00:03:38,340

So this person here is actually referring to the name which is actually the argument animal name calling



66

00:03:38,430 --> 00:03:43,850

and this person as here is actually referring to this argument.



67

00:03:43,920 --> 00:03:47,710

Ok this token is for this argument to get any money here.



68

00:03:47,730 --> 00:03:51,920

I actually created a new line character and again a person is here.



69

00:03:51,990 --> 00:03:57,050

So this person is for this argument animal color in space.



70

00:03:57,060 --> 00:03:58,520

And another person is here.



71

00:03:58,530 --> 00:03:59,830

Get any more color here.



72

00:03:59,880 --> 00:04:00,360

OK.



73

00:04:00,510 --> 00:04:01,600

Person X.



74

00:04:01,650 --> 00:04:07,020

And here we have a person and here as you can see this is a new character.



75

00:04:07,050 --> 00:04:13,840

And here I have another at person here and this person is for this animal power colon.



76

00:04:14,070 --> 00:04:16,150

And here I have a person D.



77

00:04:16,380 --> 00:04:17,640

This what this is for.



78

00:04:17,710 --> 00:04:23,700

This gets animal power here as you can see it is good get animal power and if it returns a value of



79

00:04:23,700 --> 00:04:24,500

type integer.



80

00:04:24,600 --> 00:04:28,330

So these folks talking is for this method here.



81

00:04:28,530 --> 00:04:33,130

And we have a new line character again percent as this is animal speed.



82

00:04:33,200 --> 00:04:33,950

OK.



83

00:04:34,320 --> 00:04:42,700

This is for this value colon and present the dispersant the actually is for this get speech here.



84

00:04:42,780 --> 00:04:43,560

OK.



85

00:04:44,040 --> 00:04:46,290

So hopefully that makes sense.



86

00:04:46,290 --> 00:04:50,380

Now let's actually let's actually go inside of these chats class here.



87

00:04:50,520 --> 00:04:54,480

And now it's actually putting some more lines of code here.



88

00:04:54,480 --> 00:05:01,740

So here inside of this cat class A first of all I want to actually are it the animal class from this



89

00:05:01,740 --> 00:05:02,590

cat class.



90

00:05:02,640 --> 00:05:08,800

So I want to inherit all of the features and behaviors that are inside of this animal class here.



91

00:05:09,150 --> 00:05:13,750

So I can't just type in here extends animal.



92

00:05:14,110 --> 00:05:14,410

OK.



93

00:05:14,420 --> 00:05:21,180

In this way I am inheriting all of the features all of the behaviors and instance variables that are



94

00:05:21,180 --> 00:05:22,800

actually inside of this animal class.



95

00:05:22,860 --> 00:05:23,280

OK.



96

00:05:23,430 --> 00:05:29,350

But I cannot see that the instance variables inside of these animal class here.



97

00:05:29,400 --> 00:05:29,980

OK.



98

00:05:30,180 --> 00:05:31,500

So here I can just.



99

00:05:31,740 --> 00:05:37,370

First of all I don't want to create any instance variable inside of this cat class.



100

00:05:37,470 --> 00:05:47,580

So I just need to create a constructor so public chat and inside of the practices of this class constructor



101

00:05:47,580 --> 00:05:50,270

here I need to specify some arguments.



102

00:05:50,340 --> 00:05:53,700

Strange animal name.



103

00:05:54,440 --> 00:05:55,750

OK come on.



104

00:05:55,860 --> 00:06:06,940

Strange Animal color comma in power comma and speed.



105

00:06:07,110 --> 00:06:07,690

OK.



106

00:06:07,950 --> 00:06:13,310

And then I need to open and close this constructor by using these curly braces.



107

00:06:13,400 --> 00:06:15,370

Here and just typing super.



108

00:06:15,470 --> 00:06:17,540

So super refers to the superclass.



109

00:06:17,560 --> 00:06:18,890

OK Animal class.



110

00:06:18,900 --> 00:06:23,910

And now I need to actually initialize a constructor that is inside of the superclass.



111

00:06:24,050 --> 00:06:24,680

OK.



112

00:06:24,840 --> 00:06:30,990

So first of all I need to actually as you can see inside of this animal class these are constructed



113

00:06:31,020 --> 00:06:33,680

and this constructor accepts these arguments.



114

00:06:33,720 --> 00:06:36,760

Animal named animal collect color power speed.



115

00:06:36,900 --> 00:06:40,390

So I need to assign those values to this superhero.



116

00:06:40,480 --> 00:06:43,350

OK animal name come up.



117

00:06:43,650 --> 00:06:49,300

Animal color come on power come our speed.



118

00:06:49,900 --> 00:06:50,600

OK.



119

00:06:51,090 --> 00:06:54,740

And now let's actually create another method here.



120

00:06:54,750 --> 00:06:59,220

So after this constructed as you can see I can actually create another Meffert you want to actually



121

00:06:59,250 --> 00:07:02,800

override the Mefford that is inside of this Animal class.



122

00:07:02,820 --> 00:07:06,760

So this is the method that you actually created inside of this Animal class.



123

00:07:06,840 --> 00:07:09,700

Calculate the power of Alamein.



124

00:07:09,800 --> 00:07:10,280

OK.



125

00:07:10,400 --> 00:07:16,380

In the sake of this math class because I am actually inheriting all of the features and behaviors that



126

00:07:16,380 --> 00:07:19,700

are inside of this animal class I can override that method.



127

00:07:19,770 --> 00:07:28,230

So I need to just refer to the name of that method calculate OK the overall power and then press enter



128

00:07:28,230 --> 00:07:29,360

key on your keyboard.



129

00:07:29,490 --> 00:07:36,630

So this is RMF it outside overload as you can see here publish it calculate the overall power of animal



130

00:07:36,930 --> 00:07:44,150

and inside of this Meffert as you can see it says Return super that calculate the overall power of animal.



131

00:07:44,310 --> 00:07:46,100

So it's two at least two pair here.



132

00:07:46,110 --> 00:07:49,700

As you can see the first through the superclass So the superclass is animal.



133

00:07:49,740 --> 00:07:50,660

OK.



134

00:07:50,700 --> 00:07:56,960

And as you can see here this is our superclass and it says that calculate the overall power of any one.



135

00:07:57,090 --> 00:08:01,770

So it's going to actually execute the implementations that are inside of the superclass.



136

00:08:01,770 --> 00:08:07,080

As you can see the implementation that is inside of this method that is inside of the superclass here



137

00:08:07,200 --> 00:08:07,900

as you can see.



138

00:08:08,010 --> 00:08:13,110

So it's going to actually execute this line of code here to get any more power multiplied by the value



139

00:08:13,110 --> 00:08:14,900

of the good animal speed.



140

00:08:15,030 --> 00:08:15,600

OK.



141

00:08:15,780 --> 00:08:18,300

So I think that's enough for this class here.



142

00:08:18,330 --> 00:08:19,770

This is enough.



143

00:08:20,310 --> 00:08:26,180

And now I want to actually create a two string method here.



144

00:08:26,460 --> 00:08:32,450

So in order to overwrite that method as you can see I guess I can just type in two strings.



145

00:08:33,060 --> 00:08:35,810

And as you can see here these are two string method.



146

00:08:36,090 --> 00:08:42,510

And because this Catulus actually inherits all of the features and behaviors that are inside of this



147

00:08:42,570 --> 00:08:49,240

animal class you are inheriting this two string method that is inside of these animal class.



148

00:08:49,260 --> 00:08:56,080

So this is the string method and we are inheriting this implementation as you can see it says Return



149

00:08:56,220 --> 00:08:58,100

super the string.



150

00:08:58,140 --> 00:09:03,180

So here is going to execute these lines of code that are actually inside of these two string nymphet



151

00:09:03,510 --> 00:09:06,420

that is inside of this superclass OK.



152

00:09:06,540 --> 00:09:10,860

And animal name animal color animal power and animal speed.



153

00:09:10,920 --> 00:09:11,950

As you can see here.



154

00:09:12,180 --> 00:09:12,540

OK.



155

00:09:12,540 --> 00:09:15,360

So hopefully that makes sense.



156

00:09:15,480 --> 00:09:18,660

And now it's actually adding a piece of code here.



157

00:09:18,660 --> 00:09:24,780

So after this return here as you can see I can just typing I can't just put into double quotes and I



158

00:09:24,780 --> 00:09:34,850

can just typing Chad's colon and then I can just put in a plus operator here here and chat's colon as



159

00:09:34,860 --> 00:09:36,990

you can see plus superb that two strings.



160

00:09:37,020 --> 00:09:38,160

So in this way.



161

00:09:38,280 --> 00:09:43,050

Well you want to actually output the value of these two string Meffert to the screen.



162

00:09:43,140 --> 00:09:46,930

We can see that if it is actually called from this cat class.



163

00:09:46,980 --> 00:09:54,050

OK so now let's actually go back inside this lion class here and inside of this class there's actually



164

00:09:54,050 --> 00:09:56,180

are putting some more lines of code here.



165

00:09:56,250 --> 00:10:01,380

So here inside this animal class I went to actually create something send somebody about this.



166

00:10:01,430 --> 00:10:01,910

OK.



167

00:10:01,990 --> 00:10:04,600

That is actually related only to this class.



168

00:10:04,600 --> 00:10:07,090

So these are my instance variables here.
