S… Speaker 2 (5- Variable Capture)

In the body of this lambda,

0:05

S… Speaker 2 (5- Variable Capture)

we're using the message parameter that we have declared over here.

0:08

S… Speaker 2 (5- Variable Capture)

But we can also access the local variables in the enclosing method.

0:12

S… Speaker 2 (5- Variable Capture)

So I'm going to declare a variable called prefix and

0:16

S… Speaker 2 (5- Variable Capture)

set it to hyphen.

0:17

S… Speaker 1 (5- Variable Capture)

Now,

0:18

S… Speaker 2 (5- Variable Capture)

here we can reference prefix and then append the message.

0:22

S… Speaker 1 (5- Variable Capture)

So when we run,

0:23

S… Speaker 1 (5- Variable Capture)

we get hyphen hello world.

0:26

S… Speaker 2 (5- Variable Capture)

We can also access the static fields in the enclosing class.

0:29

S… Speaker 2 (5- Variable Capture)

So I'm going to move this from here and declare it as a static

0:34

S… Speaker 2 (5- Variable Capture)

field in this class.

0:35

S… Speaker 2 (5- Variable Capture)

Public static string prefix.

0:37

S… Speaker 1 (5- Variable Capture)

Set it to hyphen.

0:39

S… Speaker 1 (5- Variable Capture)

Now we can access it in our lambda expression.

0:42

S… Speaker 2 (5- Variable Capture)

So when we run,

0:44

S… Speaker 2 (5- Variable Capture)

we get the same result as before.

0:46

S… Speaker 2 (5- Variable Capture)

We can also access the instance fields.

0:49

S… Speaker 2 (5- Variable Capture)

So I'm going to make this an instance field.

0:52

S… Speaker 2 (5- Variable Capture)

and also make the show method an instance method.

0:55

S… Speaker 1 (5- Variable Capture)

So as you can see,

0:57

S… Speaker 2 (5- Variable Capture)

we can access the prefix field.

0:58

S… Speaker 1 (5- Variable Capture)

Now,

0:59

S… Speaker 2 (5- Variable Capture)

what about this?

1:01

S… Speaker 2 (5- Variable Capture)

What do you think this represents here?

1:04

S… Speaker 2 (5- Variable Capture)

It represents the current instance of the lambdas demo class.

1:08

S… Speaker 2 (5- Variable Capture)

So if we type dot,

1:10

S… Speaker 2 (5- Variable Capture)

you can see the prefix field and the show method.

1:13

S… Speaker 2 (5- Variable Capture)

So this is one of the differences between lambda expressions and anonymous

1:17

S… Speaker 2 (5- Variable Capture)

inner classes.

1:18

S… Speaker 1 (5- Variable Capture)

In lambda expressions,

1:20

S… Speaker 2 (5- Variable Capture)

this references the enclosing object,

1:22

S… Speaker 2 (5- Variable Capture)

whereas in anonymous inner classes,

1:24

S… Speaker 2 (5- Variable Capture)

this references the current instance of the anonymous inner class.

1:28

S… Speaker 2 (5- Variable Capture)

Another difference between these two types is that anonymous inner classes can

1:33

S… Speaker 1 (5- Variable Capture)

have state.

1:33

S… Speaker 2 (5- Variable Capture)

So they can have fields to store some data in lambda expressions.

1:37

S… Speaker 2 (5- Variable Capture)

We cannot have fields because this lambda expression is just representing

1:41

S… Speaker 2 (5- Variable Capture)

an anonymous function.

1:42

S… Speaker 2 (5- Variable Capture)

So we cannot have instance fields here.

1:45

S… Speaker 2 (5- Variable Capture)

We cannot have state.

1:45

S… Speaker 2 (5- Variable Capture)

We can only access the local variables declared in the enclosing object

1:50

S… Speaker 2 (5- Variable Capture)

as well as the static and instance fields in the enclosing class.
