1
00:00:00,120 --> 00:00:07,620
In this part, we are going to talk about above us and stream in and stream is to let us using the data

2
00:00:07,620 --> 00:00:08,720
before fully to read.

3
00:00:09,150 --> 00:00:11,610
And there are two ways to read the files.

4
00:00:11,610 --> 00:00:18,390
And now you can see I already paste a large text file and there are a lot of parts here.

5
00:00:19,080 --> 00:00:26,190
And one way is to wait until it has been read and the other is to pass the piece of data halfway through.

6
00:00:26,190 --> 00:00:32,290
And a small chunk of data has picked up into a first and sent it on to the stream every time to for

7
00:00:32,460 --> 00:00:32,610
it.

8
00:00:33,030 --> 00:00:39,660
So now we back to the project and go to the app called Jazz, and we are going to delete this command

9
00:00:40,110 --> 00:00:44,060
and we are going to create a stream to read that file.

10
00:00:44,340 --> 00:00:53,130
So we are going to create a constant stream echo to create a stream.

11
00:00:53,970 --> 00:01:02,230
And we are going to post a file to this so that we are going to read this file to file an enemy's passport

12
00:01:02,400 --> 00:01:02,960
text.

13
00:01:03,390 --> 00:01:13,800
So next year we type we stream stored on data and then tunc and we're stream on data and been listening

14
00:01:13,800 --> 00:01:17,010
to the data everand on this stream.

15
00:01:17,010 --> 00:01:24,660
So every time we get a chunk of data and we will fire this Corbat and this callback is going to do a

16
00:01:24,730 --> 00:01:31,990
download, we indicate that this is a new chunk of data and then we also lock the chunk.

17
00:01:32,280 --> 00:01:40,830
Now, if we won the program by typing knocked up and you can see this before us pop up in the console

18
00:01:40,980 --> 00:01:46,920
in order to make this readable, we can go to here and at a two string method.

19
00:01:47,610 --> 00:01:53,730
So if we run the program again and you can see these are the words instead of the puffer, we can also

20
00:01:53,730 --> 00:01:56,520
has another method to make this readable.

21
00:01:56,640 --> 00:02:00,930
And this is to add and compare the method in the second argument.

22
00:02:00,940 --> 00:02:04,800
So we type and cocktailing and neuter it.

23
00:02:06,210 --> 00:02:13,670
Now we can skip the two string method because we already have the uncoupling method of using UTF.

24
00:02:14,190 --> 00:02:19,230
So if we run the program again, you can see these are also words instead of the.

25
00:02:20,040 --> 00:02:23,550
Next, we are going to create a right stream to write a file.

26
00:02:23,740 --> 00:02:32,760
So we at the constant of white screen is equal to stop create Lifestream and then we create a file name

27
00:02:32,760 --> 00:02:34,890
of white stream text.

28
00:02:35,130 --> 00:02:41,170
And then out here we can type white three dot right and back row slash.

29
00:02:41,720 --> 00:02:46,670
And at last we are going to write stream.

30
00:02:47,660 --> 00:02:48,000
Right.

31
00:02:48,000 --> 00:02:48,550
That's wrong.

32
00:02:49,230 --> 00:02:56,880
So now if we run the program by using looked at now you can see there is a white stream text here and

33
00:02:56,910 --> 00:03:00,530
a neutron and also the task inside this file.

34
00:03:00,840 --> 00:03:04,860
And at last we are going to take a look on the stream top pipe.

35
00:03:05,610 --> 00:03:10,580
And this Mafa used to take readable stream and connect it to writable stream.

36
00:03:10,950 --> 00:03:15,080
And this is a shorter way to do this same thing.

37
00:03:15,390 --> 00:03:20,250
So we can combine this and we just need to use which stream, right?

38
00:03:20,640 --> 00:03:22,360
Top pipe and white stream.

39
00:03:22,590 --> 00:03:24,870
Now, if we delete the text file again.

40
00:03:27,090 --> 00:03:36,300
And run the program and you can see the roistering file created again and all the tests are copied from

41
00:03:36,300 --> 00:03:40,740
the last tests and to the right stream text file.
