S… Speaker 2 (15- Waiting for the First Task)

Let's say there are two ways to get the current weather in a given city.

0:06

S… Speaker 2 (15- Waiting for the First Task)

Perhaps we have two different remote services,

0:09

S… Speaker 2 (15- Waiting for the First Task)

but sometimes one of these services responds a little bit slower.

0:13

S… Speaker 2 (15- Waiting for the First Task)

So we want to call these services concurrently and as soon as we get a response,

0:17

S… Speaker 2 (15- Waiting for the First Task)

we're going to display it to the user.

0:19

S… Speaker 2 (15- Waiting for the First Task)

Let me show you how to do that.

0:20

S… Speaker 2 (15- Waiting for the First Task)

So I'm going to create two completable futures.

0:23

S… Speaker 2 (15- Waiting for the First Task)

Here's the first one completable future that supply async.

0:28

S… Speaker 2 (15- Waiting for the First Task)

Let's say this is our slow link.

0:31

S… Speaker 1 (15- Waiting for the First Task)

0:32

S… Speaker 2 (15- Waiting for the First Task)

in the body of this lambda,

0:34

S… Speaker 2 (15- Waiting for the First Task)

I'm going to call long task that simulate and

0:38

S… Speaker 2 (15- Waiting for the First Task)

then return 20.

0:39

S… Speaker 2 (15- Waiting for the First Task)

That is the current weather,

0:40

S… Speaker 2 (15- Waiting for the First Task)

let's say in New York City.

0:42

S… Speaker 2 (15- Waiting for the First Task)

Now we create a second task completable

0:46

S… Speaker 2 (15- Waiting for the First Task)

future that supply async.

0:48

S… Speaker 2 (15- Waiting for the First Task)

Now this simulates a fast link.

0:50

S… Speaker 2 (15- Waiting for the First Task)

So here we return 20 immediately.

0:53

S… Speaker 2 (15- Waiting for the First Task)

Now we're going to call both these services concurrently.

0:56

S… Speaker 2 (15- Waiting for the First Task)

And as soon as one of them respond,

0:58

S… Speaker 2 (15- Waiting for the First Task)

we're going to print the result on the terminal.

1:00

S… Speaker 1 (15- Waiting for the First Task)

1:02

S… Speaker 2 (15- Waiting for the First Task)

Here we call completable future dot in the last

1:06

S… Speaker 2 (15- Waiting for the First Task)

video you learned about all of with this we can wait for the completion of all tasks.

1:10

S… Speaker 2 (15- Waiting for the First Task)

We have another method called any of this returns

1:14

S… Speaker 2 (15- Waiting for the First Task)

a new completable future that will complete as soon as one of these

1:18

S… Speaker 2 (15- Waiting for the First Task)

completable futures that we pass here completes.

1:21

S… Speaker 2 (15- Waiting for the First Task)

So just like before we have var arcs here we

1:25

S… Speaker 2 (15- Waiting for the First Task)

can pass any number of completable futures.

1:27

S… Speaker 2 (15- Waiting for the First Task)

I'm going to pass first and second.

1:30

S… Speaker 2 (15- Waiting for the First Task)

This will give us a new completable future.

1:33

S… Speaker 2 (15- Waiting for the First Task)

Let's store it in this variable fastest.

1:37

S… Speaker 2 (15- Waiting for the First Task)

Look at the type of this variable.

1:38

S… Speaker 2 (15- Waiting for the First Task)

It's a completable future of object.

1:41

S… Speaker 1 (15- Waiting for the First Task)

Now,

1:43

S… Speaker 2 (15- Waiting for the First Task)

right after we get the result,

1:45

S… Speaker 2 (15- Waiting for the First Task)

we can call then accept.

1:48

S… Speaker 2 (15- Waiting for the First Task)

We're going to consume the result.

1:50

S… Speaker 2 (15- Waiting for the First Task)

So we get the temperature and print it on a terminal.

1:54

S… Speaker 1 (15- Waiting for the First Task)

Now,

1:57

S… Speaker 2 (15- Waiting for the First Task)

let's reformat our code.

1:59

S… Speaker 2 (15- Waiting for the First Task)

That is better.

2:00

S… Speaker 1 (15- Waiting for the First Task)

So,

2:01

S… Speaker 2 (15- Waiting for the First Task)

run.

2:03

S… Speaker 2 (15- Waiting for the First Task)

See, we got the result immediately.

2:06

S… Speaker 2 (15- Waiting for the First Task)

We didn't have to wait three seconds to get the current weather from our slow service.
