Speaker 1 (16- The UnaryOperator Interface)
The last functional interface we're going to talk about is the unary operator.
0:07
S…
Speaker 1 (16- The UnaryOperator Interface)
As you can see,
0:08
S…
Speaker 1 (16- The UnaryOperator Interface)
this interface extends the function interface.
0:11
S…
Speaker 1 (16- The UnaryOperator Interface)
So a unary operator is a function that takes an argument
0:15
S…
Speaker 1 (16- The UnaryOperator Interface)
of type t and returns a value of type t.
0:17
S…
Speaker 1 (16- The UnaryOperator Interface)
So let's see how we can use this interface.
0:20
S…
Speaker 1 (16- The UnaryOperator Interface)
I'm going to declare a unary operator of
0:24
S…
Speaker 1 (16- The UnaryOperator Interface)
integer called square and set it to a lambda expression
0:28
S…
Speaker 1 (16- The UnaryOperator Interface)
like this.
0:28
S…
Speaker 1 (16- The UnaryOperator Interface)
n goes to n times n.
0:31
S…
Speaker 1 (16- The UnaryOperator Interface)
We can declare another unary operator
0:34
S…
Speaker 1 (16- The UnaryOperator Interface)
of type integer and call it increment and
0:39
S…
Speaker 1 (16- The UnaryOperator Interface)
set it to a lambda like this,
0:40
S…
Speaker 1 (16- The UnaryOperator Interface)
n goes to n plus 1.
0:42
S…
Speaker 2 (16- The UnaryOperator Interface)
So,
0:43
S…
Speaker 1 (16- The UnaryOperator Interface)
first we can increment a value and then we can
0:48
S…
Speaker 1 (16- The UnaryOperator Interface)
get the square of the result.
0:49
S…
Speaker 1 (16- The UnaryOperator Interface)
Now,
0:50
S…
Speaker 1 (16- The UnaryOperator Interface)
let's apply the sequence on 1.
0:53
S…
Speaker 1 (16- The UnaryOperator Interface)
So we're going to increment 1,
0:55
S…
Speaker 1 (16- The UnaryOperator Interface)
we get 2,
0:55
S…
Speaker 1 (16- The UnaryOperator Interface)
the square of 2 is 4.
0:57
S…
Speaker 1 (16- The UnaryOperator Interface)
Let's get the result and print it to
1:01
S…
Speaker 1 (16- The UnaryOperator Interface)
verify that our sequence of operations are working.
1:05
S…
Speaker 1 (16- The UnaryOperator Interface)
There you go.
1:06
S…
Speaker 1 (16- The UnaryOperator Interface)
So this is how we can use the unary operator in
1:10
S…
Speaker 1 (16- The UnaryOperator Interface)
