S… Speaker 1 (3- Anonymous Inner Classes)

So in the last video we passed a new instance of our console printer

0:07

S… Speaker 1 (3- Anonymous Inner Classes)

class to a Greek method As I told you sometimes we don't want to explicitly

0:11

S… Speaker 1 (3- Anonymous Inner Classes)

create a class to implement an interface Perhaps we want to implement an

0:15

S… Speaker 1 (3- Anonymous Inner Classes)

interface only once and use it for a single purpose We don't want to reuse

0:19

S… Speaker 1 (3- Anonymous Inner Classes)

that class.

0:20

S… Speaker 1 (3- Anonymous Inner Classes)

So that's where we use anonymous inner classes So

0:25

S… Speaker 1 (3- Anonymous Inner Classes)

instead of creating a new instance of the console printer class here

0:29

S… Speaker 1 (3- Anonymous Inner Classes)

we can type new

0:31

S… Speaker 2 (3- Anonymous Inner Classes)

printer.

0:31

S… Speaker 1 (3- Anonymous Inner Classes)

So we type the name of the interface and press enter.

0:34

S… Speaker 1 (3- Anonymous Inner Classes)

What we have here is called an anonymous inner

0:38

S… Speaker 1 (3- Anonymous Inner Classes)

class.

0:39

S… Speaker 1 (3- Anonymous Inner Classes)

It's anonymous because this class doesn't have a name.

0:42

S… Speaker 1 (3- Anonymous Inner Classes)

It's just an implementation and we call it an inner class because we're

0:46

S… Speaker 1 (3- Anonymous Inner Classes)

using this inside a method.

0:48

S… Speaker 1 (3- Anonymous Inner Classes)

Okay, so in this class we're

0:52

S… Speaker 1 (3- Anonymous Inner Classes)

implementing the print method.

0:53

S… Speaker 1 (3- Anonymous Inner Classes)

Here we can use a print statement to print this

0:58

S… Speaker 1 (3- Anonymous Inner Classes)

message.

0:58

S… Speaker 1 (3- Anonymous Inner Classes)

Now when we run this program

1:02

S… Speaker 1 (3- Anonymous Inner Classes)

we get the exact same result.

1:03

S… Speaker 1 (3- Anonymous Inner Classes)

So this is how we can use an anonymous inner class.

1:07

S… Speaker 1 (3- Anonymous Inner Classes)

With anonymous inner classes,

1:09

S… Speaker 1 (3- Anonymous Inner Classes)

we can achieve the same result by writing less code.

1:12

S… Speaker 1 (3- Anonymous Inner Classes)

But Java 8 introduced a better and more concise way to achieve

1:16

S… Speaker 1 (3- Anonymous Inner Classes)

the same result.

1:17

S… Speaker 1 (3- Anonymous Inner Classes)

That's called a lambda expression and we're going to look at that next.
