1

00:00:00,960 --> 00:00:03,810

And then you have another person s here.



2

00:00:03,930 --> 00:00:10,590

So he had this person as this token is for this punching power required call and Space Person D just



3

00:00:10,620 --> 00:00:12,380

punching power required.



4

00:00:12,510 --> 00:00:19,800

And if you have a person and hear new line character person as punching spit required to call him space



5

00:00:19,980 --> 00:00:25,840

gets a punch in space speed required as you can see this token this person these four these are get



6

00:00:25,880 --> 00:00:27,730

punching speeds require required hit.



7

00:00:27,870 --> 00:00:28,660

OK.



8

00:00:29,130 --> 00:00:31,470

So hopefully that makes sense.



9

00:00:31,470 --> 00:00:38,320

And now let's actually go back and go inside of these are kick boxing that of a fight here and now.



10

00:00:38,340 --> 00:00:45,510

So here after the name of this kickboxing class here as you can see just a pin here extends boxing.



11

00:00:45,960 --> 00:00:52,290

So here if you are actually inheriting all of the features and behaviors that are actually inside of



12

00:00:52,290 --> 00:00:53,830

these boxing class.



13

00:00:53,970 --> 00:00:54,790

OK.



14

00:00:55,290 --> 00:01:00,540

And as you can see inside of this boxing class this boxing class actually inherits all of the features



15

00:01:00,570 --> 00:01:03,620

and behaviors that are actually inside of this sport class.



16

00:01:03,690 --> 00:01:04,120

OK.



17

00:01:04,260 --> 00:01:09,090

And this sports class actually implements this life insurance interface.



18

00:01:09,090 --> 00:01:16,890

So because inside of this boxing class we actually are provided an implementation for this evaluate



19

00:01:16,890 --> 00:01:21,280

cost of insurance Smurfit that is inside of this life insurance interface.



20

00:01:21,390 --> 00:01:22,070

OK.



21

00:01:22,240 --> 00:01:28,410

Our inside of this kickboxing class we do not need to actually provide another implementation for that



22

00:01:28,470 --> 00:01:34,710

abstract benefit for that effort that is inside of this life insurance interface because this boxing



23

00:01:34,710 --> 00:01:37,440

class actually did this job for us.



24

00:01:37,450 --> 00:01:37,920

OK.



25

00:01:38,040 --> 00:01:43,350

This boxing class actually provided an implementation for the Smurfit and this kickboxing class can



26

00:01:43,410 --> 00:01:45,610

inherit that implementation.



27

00:01:45,820 --> 00:01:46,300

OK.



28

00:01:46,530 --> 00:01:47,640

So here.



29

00:01:47,700 --> 00:01:52,050

Let's actually create some instance variables for this kickboxing class here.



30

00:01:52,140 --> 00:01:52,550

OK.



31

00:01:52,620 --> 00:01:59,780

So as you can see here I actually declared two instance variables here ain't Keech power required to



32

00:02:00,030 --> 00:02:01,510

teach speed required.



33

00:02:01,530 --> 00:02:04,840

So let's actually declare this instance variables as private.



34

00:02:04,970 --> 00:02:05,580

OK.



35

00:02:06,040 --> 00:02:08,300

And here private's.



36

00:02:08,520 --> 00:02:13,190

So now let's actually create a constructor for these kickboxing class.



37

00:02:13,200 --> 00:02:18,150

Ok now I'm going to actually pasting this constructor here and then I'm going to try to explain to you



38

00:02:18,150 --> 00:02:19,440

what's going on here.



39

00:02:19,770 --> 00:02:24,180

So as you can see here this is my constructor for this kickboxing class here.



40

00:02:24,240 --> 00:02:24,840

OK.



41

00:02:25,140 --> 00:02:31,080

And as you can see the access modifier of my constructor is Puplick the name of my our constructor is



42

00:02:31,080 --> 00:02:31,800

kickboxing.



43

00:02:31,800 --> 00:02:35,250

So this name must be the same as the name of this class.



44

00:02:35,310 --> 00:02:35,830

OK.



45

00:02:36,000 --> 00:02:39,320

And this a constructor actually accepts some arguments.



46

00:02:39,360 --> 00:02:44,810

So the first argument that this kickboxing constructor accepts is types think name.



47

00:02:44,940 --> 00:02:46,950

The second argument is of type again.



48

00:02:46,970 --> 00:02:56,940

Strange rules in uniform int speed required in power required in punching power required int punching



49

00:02:56,940 --> 00:03:01,890

Spizz required in cheek power required an int like Keech.



50

00:03:01,920 --> 00:03:02,970

Speed required.



51

00:03:03,090 --> 00:03:10,140

And we have this this ain't custom insurance here and here I'm going to the inside of this constructive



52

00:03:10,310 --> 00:03:10,760

here.



53

00:03:10,830 --> 00:03:13,380

I need to actually initialize.



54

00:03:13,570 --> 00:03:17,400

OK I need to initialize the constructor of the superclass.



55

00:03:17,400 --> 00:03:19,400

So what is the superclass the superclass.



56

00:03:19,400 --> 00:03:20,940

Is this boxing class.



57

00:03:21,780 --> 00:03:30,360

So here super name rule is uniform speed required the power required punching power required punching



58

00:03:30,360 --> 00:03:33,450

speeds required and this cost of insurance here.



59

00:03:33,550 --> 00:03:39,690

OK so if you go back inside this boxing class as you can see this class actually accepts some arguments



60

00:03:39,880 --> 00:03:45,720

as against it is a constructor that is inside of this class accepts some arguments as you can see name



61

00:03:45,990 --> 00:03:52,830

rules uniform speed required the power required punching power required punching speeds required and



62

00:03:52,830 --> 00:03:53,880

this cost.



63

00:03:53,940 --> 00:03:55,410

Cost of insurance.



64

00:03:55,470 --> 00:04:01,640

So inside of a kickboxing class we need to initialize the are actually the constructor of the superclass.



65

00:04:01,800 --> 00:04:06,910

OK because we are inheriting all of the features and behaviors that are inside of this muxing class



66

00:04:06,990 --> 00:04:14,010

OK and then we can actually initialize the instance variables that are actually specific only to this



67

00:04:14,170 --> 00:04:15,240

sheet boxing class.



68

00:04:15,390 --> 00:04:23,610

Is that a Keech power required assignment operator Keech power requires these dots Keech Spizz required



69

00:04:23,970 --> 00:04:27,270

assignments operator Keech Spizz requires.



70

00:04:27,300 --> 00:04:33,200

So now this actually creates some getters and setters for these instance variables.



71

00:04:33,210 --> 00:04:34,580

So here just right click here.



72

00:04:34,580 --> 00:04:40,370

Inside this class generate get here and set here and select.



73

00:04:40,560 --> 00:04:44,280

These these these two instance variables and then click on OK.



74

00:04:44,490 --> 00:04:48,230

So as you can see here the ID are automatically generated.



75

00:04:48,450 --> 00:04:50,520

These are get hills and settles for us.



76

00:04:50,530 --> 00:04:56,670

OK so now inside of this class this actually overwrite the twisting method that we actually inherit



77

00:04:56,910 --> 00:04:58,410

from the superclass.



78

00:04:58,410 --> 00:05:03,730

So what is the superclass the superclass is this boxing class and we can actually inherit these two



79

00:05:03,750 --> 00:05:04,960

string Meffert here.



80

00:05:05,000 --> 00:05:05,530

OK.



81

00:05:05,680 --> 00:05:09,440

So inside of this kickboxing class that's actually just typing to stream.



82

00:05:09,530 --> 00:05:10,070

OK.



83

00:05:10,280 --> 00:05:13,760

And here in say the policeman for let's actually read this line of code here.



84

00:05:14,060 --> 00:05:18,940

And that's actually putting our own implementations that are actually in specific.



85

00:05:19,010 --> 00:05:21,170

Only two Ds these kickboxing class.



86

00:05:21,170 --> 00:05:24,250

So here I can just type in return OK.



87

00:05:24,430 --> 00:05:29,380

Stream data formats and inside the.



88

00:05:29,460 --> 00:05:33,740

I'm going to actually actually are pasting a piece of code and then I'm going to explain to you what's



89

00:05:33,740 --> 00:05:34,760

going on here.



90

00:05:34,790 --> 00:05:42,460

So here as you can see inside it up of course I actually specified the formatting of my string value.



91

00:05:42,470 --> 00:05:43,460

OK.



92

00:05:43,470 --> 00:05:44,190

Percent.



93

00:05:44,240 --> 00:05:49,550

So this person is for these superb that string Meffert here as you can see I am calling the twisting



94

00:05:49,550 --> 00:05:54,360

method that is inside of the superclass boxing on the super here.



95

00:05:54,410 --> 00:05:55,110

OK.



96

00:05:55,340 --> 00:05:58,370

So it's going actually to execute these lines of code.



97

00:05:58,370 --> 00:06:02,690

This piece of code as you can see here inside of these two string if it is going I should return a string



98

00:06:02,690 --> 00:06:03,250

value.



99

00:06:03,320 --> 00:06:03,950

OK.



100

00:06:04,370 --> 00:06:09,860

That has actually this throughput that was strange I guess punching power required and get punching



101

00:06:09,860 --> 00:06:10,820

Spizz require you.



102

00:06:10,900 --> 00:06:11,680

OK.



103

00:06:12,200 --> 00:06:17,100

And here as you can see we have a per cent and a new character.



104

00:06:17,120 --> 00:06:19,400

A percent is here as you can see it is this.



105

00:06:19,460 --> 00:06:23,660

This is for this Keech power required Colan person deep.



106

00:06:23,690 --> 00:06:31,150

This is for a good power the quiet person as person person and person as hard as you can see Keech speeds



107

00:06:31,160 --> 00:06:35,000

requires a colon and we have a person here.



108

00:06:35,030 --> 00:06:37,980

And this is for get Keech speed required.



109

00:06:38,120 --> 00:06:41,920

And here we need to put a semicolon at the end of our statement.



110

00:06:42,110 --> 00:06:46,340

And now let's actually go inside of these students class.



111

00:06:46,340 --> 00:06:47,100

OK.



112

00:06:47,140 --> 00:06:53,470

And as you know a student cannot be actually a sport or K as a student is actually.



113

00:06:53,480 --> 00:06:54,950

And other concepts are key.



114

00:06:55,070 --> 00:07:01,040

So if the student can actually implement it can actually implement this life insurance interface life



115

00:07:01,040 --> 00:07:01,810

insurance.



116

00:07:01,910 --> 00:07:08,360

So here we need to actually pro-white as you can see it says the class student must either be declared



117

00:07:08,420 --> 00:07:14,860

as abstract as an abstract class or implement abstract method evaluate cost of insurance.



118

00:07:15,020 --> 00:07:22,040

OK so here because student is not an abstract concept we need to actually provide an implementation



119

00:07:22,490 --> 00:07:27,280

for the abstract method that is inside of this life insurance interface.



120

00:07:27,410 --> 00:07:27,830

OK.



121

00:07:27,860 --> 00:07:32,830

So first of all let's actually provide some instance variables for this student's class.



122

00:07:32,950 --> 00:07:33,440

OK.



123

00:07:33,680 --> 00:07:39,140

So now we're going to actually paste in some instance variables for these students class.



124

00:07:39,140 --> 00:07:44,410

So as you can see here these are my instance value bets for this student class.



125

00:07:44,450 --> 00:07:48,610

String name string course name into custom insurance.



126

00:07:48,650 --> 00:07:52,540

So he had actually declare this instance variables as private.



127

00:07:52,790 --> 00:07:53,480

OK.



128

00:07:53,490 --> 00:07:56,830

Here private and private here.



129

00:07:56,870 --> 00:08:02,850

OK so now let's actually create a structure for these student class.



130

00:08:02,870 --> 00:08:07,550

Now I'm going to paste in this constructor here and then I'm going to explain to you what's going on



131

00:08:07,550 --> 00:08:08,830

here OK.



132

00:08:08,990 --> 00:08:12,960

So as you can see here this is my constructor for these students class.



133

00:08:13,010 --> 00:08:20,600

So publish student and this constructor actually accepts some arguments here as you can see string name



134

00:08:20,870 --> 00:08:22,360

string course name end.



135

00:08:22,370 --> 00:08:23,620

Cost of insurance.



136

00:08:23,750 --> 00:08:29,870

And here as you can see inside of this constructor I am actually instantiating the instance variables



137

00:08:30,140 --> 00:08:33,210

that are actually created inside of this student class.



138

00:08:33,230 --> 00:08:41,930

OK so does that a name assignment operator name does that call same assignment operator course name.



139

00:08:42,000 --> 00:08:45,330

That are cost of insurance assignments operator.



140

00:08:45,410 --> 00:08:46,480

Cost of insurance.



141

00:08:46,520 --> 00:08:54,710

OK so now let's create some getters and setters for these instance variables that are inside of this



142

00:08:54,890 --> 00:08:56,210

student class.



143

00:08:56,210 --> 00:08:58,590

So here inside this class just right click here.



144

00:08:58,640 --> 00:08:59,240

OK.



145

00:08:59,420 --> 00:09:00,050

Generate.



146

00:09:00,170 --> 00:09:00,800

OK.



147

00:09:01,070 --> 00:09:07,190

And then I click on get here and setter here and here select all of these instance variables and then



148

00:09:07,190 --> 00:09:08,280

click OK.



149

00:09:08,500 --> 00:09:13,680

So as you can see here the Android studio ID generated these are instance.



150

00:09:13,730 --> 00:09:16,160

These are getters and setters automatically for us.



151

00:09:16,160 --> 00:09:17,190

OK.



152

00:09:17,360 --> 00:09:18,940

So hopefully that makes sense.



153

00:09:19,190 --> 00:09:26,960

And now as you can see the compiler is complaining and it says the classes students must either be declared



154

00:09:27,020 --> 00:09:31,540

abstract or implement abstract method evaluate costs of insurance.



155

00:09:31,610 --> 00:09:37,010

So here we need to actually implement the method evaluate cost of insurance.



156

00:09:37,020 --> 00:09:43,440

OK so evaluate cost of insurance and as you can see your overriding Ismir for the fee.



157

00:09:43,460 --> 00:09:48,350

So let's actually get into this implementation in say that this evaluate costs of insurance Smurfette



158

00:09:48,660 --> 00:09:52,490

and now inside of this measure they can actually be putting our own implementations.



159

00:09:52,490 --> 00:09:58,760

So now I can I should return the value of the cost of insurance instance variable and that I need to



160

00:09:58,760 --> 00:10:01,610

put in a semi-colon at the end of my statement.



161

00:10:01,760 --> 00:10:02,190

OK.



162

00:10:02,260 --> 00:10:04,430

As you can see here I have a good term for it.



163

00:10:04,450 --> 00:10:07,430

And I have a sitter in my faith for this cost of insurance.



164

00:10:07,510 --> 00:10:12,370

OK so here I could just refer to the name of this get her if it gets cost of insurance.



165

00:10:12,430 --> 00:10:12,910

OK.
