Java 8 for Experienced Developers: Lambdas, Stream API & Beyond

## `UnaryOperator<T>`

The `UnaryOperator<T>` interface represents a function that takes one argument of type `T` and returns a value of the same type. This is similar to the `Function` interface, which is a parent to the `UnaryOperator` interface.

The `UnaryOperator` does not define any new abstract methods. Since it extends the `Function` interface from the same package, it inherits the following method from the `Function` interface :
