1

00:00:00,330 --> 00:00:06,720

And when it reaches to these are and curly brace of the Smurfit this variable is no longer a life OK.



2

00:00:06,750 --> 00:00:09,700

And that's the end of this valuable life.



3

00:00:09,740 --> 00:00:10,850

This local radio.



4

00:00:10,990 --> 00:00:11,400

OK.



5

00:00:11,520 --> 00:00:16,940

But when you create a valuable insight of this class inside of the class itself that's valuable.



6

00:00:16,950 --> 00:00:20,830

It's going to be alive for the lifetime of your application.



7

00:00:20,940 --> 00:00:25,800

So hopefully that makes sense and if you have any questions about this concept please post the discussion



8

00:00:25,800 --> 00:00:29,100

in the course and then I do my best to answer your questions.



9

00:00:29,370 --> 00:00:34,830

And another important point that I wanted to talk about as you can see here as I said before in the



10

00:00:34,830 --> 00:00:41,280

previous sections we actually start counting from number zero again not number one.



11

00:00:41,310 --> 00:00:41,860

OK.



12

00:00:41,870 --> 00:00:49,920

So when he I actually specified that if the length of this value this string value is greater than or



13

00:00:49,950 --> 00:00:56,670

equal to number nine this means if the characters if the number of characters of this value is 10.



14

00:00:56,790 --> 00:00:58,410

So if you start from number zero.



15

00:00:58,500 --> 00:01:03,100

So as you can see here now our application is actually running on this emulator here.



16

00:01:03,150 --> 00:01:06,450

And let's actually create some random numbers OK.



17

00:01:06,780 --> 00:01:11,640

And as you can see here now our button is invisible and it actually generated some random random numbers



18

00:01:11,640 --> 00:01:12,110

here.



19

00:01:12,120 --> 00:01:14,280

So let's actually count the random numbers here.



20

00:01:14,370 --> 00:01:22,140

0 1 2 3 4 5 6 7 8 9.



21

00:01:22,370 --> 00:01:22,810

OK.



22

00:01:22,920 --> 00:01:29,640

So that's the result of this if statement here that I actually created and I said that if the length



23

00:01:29,670 --> 00:01:32,860

of this string value is greater than or equal to number 9.



24

00:01:33,030 --> 00:01:38,560

So it is of value the length of this value is actually equal to number 9.



25

00:01:38,700 --> 00:01:41,400

So it is going to actually make this button invisible.



26

00:01:41,700 --> 00:01:46,450

So always remember in programming we always count from numbers zero.



27

00:01:46,710 --> 00:01:48,200

OK this is really important.



28

00:01:48,210 --> 00:01:49,620

Hopefully that makes sense.



29

00:01:49,980 --> 00:01:52,980

And if you have any questions please post the discussion in the course.



30

00:01:53,000 --> 00:01:54,900

I'll do my best to answer your questions.



31

00:01:54,900 --> 00:01:59,160

Aaron thank you very much for watching and I'll see you in the next tutorial.
