1

00:00:00,420 --> 00:00:05,940

So as you can see here dismembered actually returns a printable representation of this object.



2

00:00:05,940 --> 00:00:06,540

OK.



3

00:00:06,810 --> 00:00:09,570

So this next class refers to that specific class.



4

00:00:09,570 --> 00:00:11,760

For example our Animal class.



5

00:00:11,820 --> 00:00:12,380

OK.



6

00:00:12,540 --> 00:00:18,840

So if inside the Animal class this is our Animal class and that's our class here refers to that.



7

00:00:18,860 --> 00:00:24,520

And in my class for example if you want to actually override this method from another class.



8

00:00:24,540 --> 00:00:27,290

So inside the Animal class you are actually 18.



9

00:00:27,310 --> 00:00:28,430

Dismiss it.



10

00:00:28,440 --> 00:00:29,020

OK.



11

00:00:29,400 --> 00:00:35,320

So I get class that gets named Plus at slanged plus integer plus integers that are two hex string.



12

00:00:35,340 --> 00:00:39,880

Ok so I don't want this code to be executed in my own code.



13

00:00:39,930 --> 00:00:44,310

Ok so I just need to delete this return that to a strange method here.



14

00:00:44,310 --> 00:00:44,800

OK.



15

00:00:44,880 --> 00:00:52,080

As you can see here this super key word here actually fares to the superclass to the class that we are



16

00:00:52,080 --> 00:00:54,960

actually inheriting this method from.



17

00:00:54,960 --> 00:00:57,650

So this super refers to the Object class.



18

00:00:57,770 --> 00:00:58,570

OK.



19

00:00:59,070 --> 00:01:03,070

And here as you can see it says Return superstar to history.



20

00:01:03,240 --> 00:01:09,850

And it means that return the value of the execution of this line of code here.



21

00:01:09,870 --> 00:01:10,520

OK.



22

00:01:10,710 --> 00:01:13,970

So when you say return superhet that was thrilling.



23

00:01:14,340 --> 00:01:18,350

It means that it's going actually only execute this line of code here.



24

00:01:18,360 --> 00:01:24,800

OK return gets class that gets named plus signed plus integer that to heggs string has scored.



25

00:01:24,840 --> 00:01:28,820

So I don't want this code here to be executed.



26

00:01:28,830 --> 00:01:29,270

OK.



27

00:01:29,340 --> 00:01:34,360

Return get class that gets name plus sign plus integer that will heggs stream.



28

00:01:34,390 --> 00:01:39,010

OK so then you say return super that start to strange.



29

00:01:39,030 --> 00:01:44,230

It means that this super refers to the superclass.



30

00:01:44,230 --> 00:01:51,210

This object class datastream refers to the implementation of these MFL.



31

00:01:51,210 --> 00:01:53,680

OK so this is the implementation of this method.



32

00:01:53,700 --> 00:01:57,110

Ok this line of code is the implementation of that method.



33

00:01:57,210 --> 00:02:03,450

So I don't want this code to be executed so I just need to delete this line of code here and here.



34

00:02:03,480 --> 00:02:10,000

I can actually put in my own instruction as my own implementations inside these two string Meffert.



35

00:02:10,040 --> 00:02:20,630

OK so I just want to type in return as strange Dadds format and an inside Apprentice's.



36

00:02:20,670 --> 00:02:37,460

I need to put into double quotes percent as Colan percent as space percent as Colan percent as space



37

00:02:37,730 --> 00:02:42,170

person the space per cent the OK.



38

00:02:42,560 --> 00:02:49,160

And then I need to put in a comma here and now I want to actually specify the values that is going to



39

00:02:49,160 --> 00:02:51,070

be related to these tokens here.



40

00:02:51,080 --> 00:02:51,850

OK.



41

00:02:52,040 --> 00:02:59,750

So for the first argument as you can see this person is to put in a value of type A strange name.



42

00:03:00,430 --> 00:03:01,630

OK come on.



43

00:03:01,730 --> 00:03:08,150

And for the second token as you can see here I need to put in another argument of type A strange name



44

00:03:08,250 --> 00:03:12,580

or refer to the name of this name instance variable comma.



45

00:03:12,850 --> 00:03:16,760

And my first argument again is going to be of type as strange.



46

00:03:16,930 --> 00:03:20,920

So as you can see here it is Fred Torchin as you can see is present as.



47

00:03:20,960 --> 00:03:24,710

So I need to actually put in an argument of type as strange.



48

00:03:24,880 --> 00:03:27,950

OK so I just need to put it into double quotes here.



49

00:03:28,240 --> 00:03:30,390

Caller.



50

00:03:31,100 --> 00:03:34,830

And then comma color.



51

00:03:35,380 --> 00:03:36,120

OK.



52

00:03:36,550 --> 00:03:41,300

So again I'm putting a comma here and here I need to actually put in.



53

00:03:41,350 --> 00:03:43,870

So as you can see here this color here is four.



54

00:03:43,880 --> 00:03:47,310

These are token here percent as OK.



55

00:03:47,410 --> 00:03:52,810

So because I actually put a colon here I don't need to actually put a colon here and here.



56

00:03:52,850 --> 00:03:59,250

And for this token here percent the I need to actually put in an argument of type integer.



57

00:03:59,410 --> 00:04:03,800

So amount of speed comma.



58

00:04:04,090 --> 00:04:10,700

And for this token here again I need to put in an argument of type integer amount of power.



59

00:04:10,720 --> 00:04:11,510

OK.



60

00:04:12,100 --> 00:04:14,830

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



61

00:04:14,890 --> 00:04:15,440

OK.



62

00:04:15,630 --> 00:04:21,970

OK whenever I call this Smurfette it's going to actually give me a human readable is 3 and about those



63

00:04:22,060 --> 00:04:24,680

are valuable or objects.



64

00:04:24,840 --> 00:04:25,460

OK.



65

00:04:25,720 --> 00:04:32,050

So this is the job of this two string method and this effect is from the from this object class and



66

00:04:32,080 --> 00:04:34,810

we are inheriting this method from the Object class.



67

00:04:34,990 --> 00:04:39,540

And that's why we actually put this house at sign over right.



68

00:04:39,550 --> 00:04:40,560

Key word here.



69

00:04:40,570 --> 00:04:41,020

OK.



70

00:04:41,110 --> 00:04:46,200

We are redefining or overwriting the Smurfette inside our own class.



71

00:04:46,240 --> 00:04:50,080

You are actually putting our own implementations inside this method.



72

00:04:50,230 --> 00:04:50,900

OK.



73

00:04:51,070 --> 00:04:53,010

So hopefully that makes sense.



74

00:04:53,290 --> 00:04:56,840

So let's actually go inside the main activity that java file.



75

00:04:57,160 --> 00:05:03,940

And here I want to actually access the Animal class and create an object from this animal class and



76

00:05:03,940 --> 00:05:07,160

then output those values to the screen.



77

00:05:07,290 --> 00:05:12,160

OK so now let's actually create an object from this animal class.



78

00:05:12,160 --> 00:05:12,970

OK.



79

00:05:13,000 --> 00:05:19,240

So inside the main activity that Javal and inside the inside the uncreate method here I need to refer



80

00:05:19,240 --> 00:05:21,720

to the name of this animal class animal.



81

00:05:22,000 --> 00:05:25,510

And here I need to actually give a name to this object.



82

00:05:25,510 --> 00:05:32,740

For example animal one and I need to put in an assignment operator here and then I need to actually



83

00:05:32,740 --> 00:05:34,600

put in the new key word here.



84

00:05:34,720 --> 00:05:38,130

And again I need to actually defer to the name of this Animal class.



85

00:05:38,140 --> 00:05:43,780

Ok so I need to actually putting up a semi-colon at the end of my statement.



86

00:05:43,840 --> 00:05:47,790

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



87

00:05:47,890 --> 00:05:50,150

The Android studio is now complaining.



88

00:05:50,170 --> 00:05:50,840

Why.



89

00:05:51,040 --> 00:05:56,590

Because inside the animal class I've actually created a constructor that is going to actually accept



90

00:05:56,620 --> 00:05:57,740

for arguments.



91

00:05:57,760 --> 00:05:58,500

OK.



92

00:05:58,720 --> 00:06:06,100

And when ever that we want to actually create an object from this animal class this constructor is going



93

00:06:06,100 --> 00:06:06,970

to be called.



94

00:06:07,000 --> 00:06:10,580

So we need to actually putting those arguments here.



95

00:06:10,690 --> 00:06:11,190

OK.



96

00:06:11,380 --> 00:06:14,830

So the first argument must be of type as string.



97

00:06:14,860 --> 00:06:15,550

OK.



98

00:06:15,880 --> 00:06:19,720

And here I need to specify the name of this animal.



99

00:06:20,110 --> 00:06:26,000

So I just need to put in two double quotes here and the name of this animal is for example Tiger.



100

00:06:26,110 --> 00:06:28,270

And then I need to put in a comma here.



101

00:06:28,270 --> 00:06:32,820

The second argument I must specify the color of this target tiger.



102

00:06:32,830 --> 00:06:33,430

OK.



103

00:06:33,760 --> 00:06:42,410

So I just need to put into double calls here so excited about cotes I can just type in orange for example.



104

00:06:42,860 --> 00:06:45,450

And that again I need to put in a comma here.



105

00:06:45,590 --> 00:06:52,230

And my first argument must specify the amount of speed of this object.



106

00:06:52,250 --> 00:06:52,760

OK.



107

00:06:52,880 --> 00:06:59,180

As you can see here in amount of speed of type and so I need to put in a value of type int here.



108

00:06:59,450 --> 00:07:01,490

For example number 60.



109

00:07:01,700 --> 00:07:02,250

OK.



110

00:07:02,390 --> 00:07:09,470

And then I need to put in a comma here and here again I need to actually put in another argument here



111

00:07:09,500 --> 00:07:16,160

of type int and here I need to actually specify the amount of power of this object here.



112

00:07:16,310 --> 00:07:19,080

As you can see this argument is of type int.



113

00:07:19,220 --> 00:07:24,400

So I need to actually passing a value of type for example number 80.



114

00:07:24,680 --> 00:07:33,680

OK so now let's actually create some objects from the text view class and then refer to these components



115

00:07:33,950 --> 00:07:35,500

inside this screen here.



116

00:07:35,540 --> 00:07:39,640

Ok for example this animal takes the view here.



117

00:07:40,010 --> 00:07:45,940

So in so the main activity that you are here I need to actually create some text view objects so I can



118

00:07:45,940 --> 00:07:53,230

need to actually first to the name of the text your class and the name of my object is TXI the animal



119

00:07:53,920 --> 00:07:58,150

and assignment operator here an assignment operator here.



120

00:07:58,400 --> 00:08:01,050

And then I need to actually put in a pair of round brackets.



121

00:08:01,070 --> 00:08:07,370

So inside and out brackets I need to actually cast this object to a text you object.



122

00:08:07,370 --> 00:08:11,140

I talked more about casting objects later in this tutorial.



123

00:08:11,210 --> 00:08:13,590

But for now just typing text view.



124

00:08:13,810 --> 00:08:14,780

OK everyone.



125

00:08:14,780 --> 00:08:17,830

Now let's actually create some text you objects.



126

00:08:18,050 --> 00:08:22,880

So first of all we need to refer to the name of the text you class and then we need to actually give



127

00:08:22,940 --> 00:08:25,770

a name to this object to the animal.



128

00:08:26,630 --> 00:08:33,460

And then we put in an assignment operator here and then mean to cast this object to a text you object.



129

00:08:33,510 --> 00:08:38,000

Talk more about casting objects in this tutorial.



130

00:08:38,270 --> 00:08:42,550

But for now know that you need to actually cast this object to a test you object.



131

00:08:42,560 --> 00:08:43,260

OK.



132

00:08:43,730 --> 00:08:51,270

And then when you type in here find view by id r that ID that is the animal.



133

00:08:51,570 --> 00:08:52,180

OK.



134

00:08:52,400 --> 00:08:55,930

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



135

00:08:56,690 --> 00:09:00,790

And again I need to refer to the name of the text your class.



136

00:09:02,080 --> 00:09:03,890

OK.



137

00:09:05,170 --> 00:09:21,200

The and my second component is Chat chat and then I put in an assignment operator here takes to find



138

00:09:21,680 --> 00:09:26,570

the ID are that Id dot the chats.



139

00:09:26,660 --> 00:09:28,020

OK.



140

00:09:28,970 --> 00:09:35,930

Again I want to create another text you object to the TXI the lion.



141

00:09:36,470 --> 00:09:45,440

And then I put in an assignment operator here and then I cast this object to a text you object find



142

00:09:45,560 --> 00:09:52,220

view by id artist Id dot the line.



143

00:09:52,530 --> 00:09:53,650

OK.



144

00:09:54,280 --> 00:09:54,980

Takes you



145

00:09:57,720 --> 00:09:59,330

DHT.



146

00:09:59,910 --> 00:10:01,020

Let's see our.



147

00:10:01,290 --> 00:10:01,620

OK.



148

00:10:01,620 --> 00:10:08,190

This is our Lepard takes you here to the leopard.



149

00:10:09,270 --> 00:10:15,830

And then I put an assignment operator here and then I cast this object to a text you object.



150

00:10:16,090 --> 00:10:25,510

Find by ID or that idea that takes the Leppert.



151

00:10:25,730 --> 00:10:26,380

OK.
