Abstract
When a Function object’s input type is the same as its output type, an Operator interface can be used in place of a Function. Operator interfaces define a single type parameter. UnaryOperator is a functional interface with one type parameter T that inherits Function<T, T>. BinaryOperator is a functional interface with one type parameter T that inherits BiFunction<T, T, T>.
