00:00:00,540 --> 00:00:06,000

Hello this is Martez awkward and it is actually all we're going to actually work on this clear about



2

00:00:06,000 --> 00:00:06,460

it.



3

00:00:06,720 --> 00:00:12,600

So let's go inside our country a little class and before you incur the price of this calculator class



4

00:00:12,600 --> 00:00:14,070

we're going to create a method.



5

00:00:14,070 --> 00:00:22,520

So private voyde and the name of that effort is going to be clear tacts.



6

00:00:22,590 --> 00:00:27,720

So I want to put apart apprentices here and I want to open and close this method by using these curly



7

00:00:27,720 --> 00:00:28,560

braces.



8

00:00:28,920 --> 00:00:36,660

So here first of all we said that this number at liff assignment operator an interesting value is Thring



9

00:00:36,660 --> 00:00:38,490

number and right.



10

00:00:38,640 --> 00:00:46,620

Assignment operator two coats empty string where you get ready to assign a number to zero to the calculations



11

00:00:46,620 --> 00:00:47,950

result variable.



12

00:00:49,620 --> 00:00:56,370

And then semicolon for the current number we are going to also assign an interesting value.



13

00:00:56,570 --> 00:01:07,210

And for the current OPERATOR You're going to assign the value to this variable for that it still results



14

00:01:07,540 --> 00:01:08,430

takes you.



15

00:01:08,490 --> 00:01:10,900

You are going to set a value number zero.



16

00:01:11,910 --> 00:01:13,450

As the initial value.



17

00:01:14,090 --> 00:01:22,140

And for the calculations valuable for the calculations string variable you're likely to assign an empty



18

00:01:22,140 --> 00:01:23,140

string value.



19

00:01:23,380 --> 00:01:29,500

And for that use the calculations takes you are going to assigned an empty string that you all for example



20

00:01:29,510 --> 00:01:32,400

as we can just put number 0 here.



21

00:01:32,400 --> 00:01:33,390

That's it.



22

00:01:33,390 --> 00:01:41,550

So now of we can actually call the Smurfette from the PTEN clear case statement inside our switch statement.



23

00:01:41,580 --> 00:01:43,250

So let's scroll to the top.



24

00:01:44,480 --> 00:01:46,750

And here we have a number.



25

00:01:46,910 --> 00:01:48,600

So let's scroll down here.



26

00:01:49,770 --> 00:01:55,110

We have this pretty clear case became clear so we can see a clear path.



27

00:01:55,260 --> 00:01:56,010

That's it.



28

00:01:56,190 --> 00:01:58,190

Let's run the app.



29

00:01:58,320 --> 00:01:59,910

Let me show you the emulator.



30

00:01:59,910 --> 00:02:10,660

So for example Number five multiplied by two equal to number 10 plus six equal to 16.



31

00:02:10,910 --> 00:02:13,520

So I want to for example clear everything.



32

00:02:13,520 --> 00:02:23,610

Now everything is cleared and here we can see for example Number five multiplied by two equal number



33

00:02:23,610 --> 00:02:24,290

10.



34

00:02:24,450 --> 00:02:25,020

Right.



35

00:02:25,020 --> 00:02:29,610

So now you can see that the clear button is actually executed.



36

00:02:29,910 --> 00:02:38,100

But here when I clicked on the XTi clear you can see that inside this takes the calculations there is



37

00:02:38,130 --> 00:02:42,500

no actually number zero here.



38

00:02:42,510 --> 00:02:42,980

Right.



39

00:02:43,140 --> 00:02:48,970

And that's because of this on my face here because let's take a look at this ugly method here.



40

00:02:49,080 --> 00:02:52,580

At the end of this Arncliffe effort after this statement is executed.



41

00:02:52,780 --> 00:02:57,550

We're saying he makes the calculations that said text calculations 3.



42

00:02:57,960 --> 00:03:05,720

So before we actually assign a number to zero as the value of this takes you here we are actually the



43

00:03:06,020 --> 00:03:08,090

MT-NW the value of the calculation is stunning.



44

00:03:08,090 --> 00:03:09,690

So let me show you my friend.



45

00:03:09,930 --> 00:03:12,720

You can see that we assigned an empty string value to this value.



46

00:03:12,760 --> 00:03:15,540

So that's why you can see this number zero here.



47

00:03:15,690 --> 00:03:18,790

So let me actually did it this number zero here as the value of the set.



48

00:03:18,810 --> 00:03:25,950

And that's just a sign an empty string value as the value of this text takes you here.



49

00:03:26,250 --> 00:03:33,520

And if you want to you can just delete this line of code because we just set the value of the calculation



50

00:03:33,520 --> 00:03:36,960

string as the value of the ticks the calculations are in.



51

00:03:36,990 --> 00:03:42,740

Inside the unclear method regardless of the switch statement so we can just delete this line of code.



52

00:03:42,960 --> 00:03:48,330

And if you want to put number 0 as the value of that is the calculations we can just assign the value



53

00:03:48,330 --> 00:03:52,050

number zero inside the two codes to these valuable calculations.



54

00:03:52,320 --> 00:03:54,610

So let me show you the applicant.



55

00:03:54,700 --> 00:03:57,750

Let's run the at now.



56

00:03:58,280 --> 00:04:07,370

For example you can see number zero he has a five multiplied by free equal and plus two equals.



57

00:04:07,370 --> 00:04:08,700

So let's get the clear.



58

00:04:08,720 --> 00:04:10,130

Now you can see this clear within here.



59

00:04:10,130 --> 00:04:23,210

So again eight multiplied by two equals Sixteen plus four equal to any divided by two equal or ten minus



60

00:04:23,360 --> 00:04:29,390

five equal five multiplied by four equal to any.



61

00:04:29,390 --> 00:04:34,280

So you can see that our calculator application works perfectly.



62

00:04:34,280 --> 00:04:36,790

So that's it that's enough for this application.



63

00:04:36,800 --> 00:04:44,060

And I think this was the last application that I actually uploaded to this course because of we cannot



64

00:04:44,090 --> 00:04:50,550

add more than five hundred and fifty lectures to the course and we already reached that limitation.



65

00:04:50,960 --> 00:04:58,910

So if you have any questions about actually creating Android applications about anything in Android



66

00:04:59,030 --> 00:05:05,870

regarding creating Android applications or Java please post the discussion in the course and then I



67

00:05:05,870 --> 00:05:08,370

will do my best to answer all of your questions.



68

00:05:08,540 --> 00:05:14,160

Thanks very much for watching again and hope to see you again bye.
