Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterfacepublic interfaceDoubleUnaryOperator
```
Represents an operation on a singledouble-valued operand that produces adouble-valued result. This is the primitive type specialization ofUnaryOperator fordouble.
This is afunctional interface whose functional method isapplyAsDouble(double).
Since:
1.8

All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`defaultDoubleUnaryOperator`	`andThen(DoubleUnaryOperator after)`	Returns a composed operator that first applies this operator to its input, and then applies the`after` operator to the result.
`double`	`applyAsDouble(double operand)`	Applies this operator to the given operand.
`defaultDoubleUnaryOperator`	`compose(DoubleUnaryOperator before)`	Returns a composed operator that first applies the`before` operator to its input, and then applies this operator to the result.
`staticDoubleUnaryOperator`	`identity()`	Returns a unary operator that always returns its input argument.

- Method Detail
  - applyAsDouble
```
double applyAsDouble(double operand)
```
    Applies this operator to the given operand.
    Parameters:
    operand - the operand
    Returns:
    the operator result
  - compose
```
default DoubleUnaryOperator compose(DoubleUnaryOperator before)
```
    Returns a composed operator that first applies thebefore operator to its input, and then applies this operator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.
    Parameters:
    before - the operator to apply before this operator is applied
    Returns:
    a composed operator that first applies thebefore operator and then applies this operator
    Throws:
    NullPointerException - if before is null
    See Also:
    andThen(DoubleUnaryOperator)
  - andThen
```
default DoubleUnaryOperator andThen(DoubleUnaryOperator after)
```
    Returns a composed operator that first applies this operator to its input, and then applies theafter operator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.
    Parameters:
    after - the operator to apply after this operator is applied
    Returns:
    a composed operator that first applies this operator and then applies theafter operator
    Throws:
    NullPointerException - if after is null
    See Also:
    compose(DoubleUnaryOperator)
  - identity
```
static DoubleUnaryOperator identity()
```
    Returns a unary operator that always returns its input argument.
    Returns:
    a unary operator that always returns its input argument
