Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface Function<@NonNull T, @NonNull R>
A functional interface that takes a value and returns another value, possibly with a different type and allows throwing a checked exception.
