BinaryOperator

public interface BinaryOperator
implements BiFunction<T, T, T>

java.util.function.BinaryOperator<T>

Represents an operation upon two operands of the same type, producing a result of the same type as the operands. This is a specialization of BiFunction for the case where the operands and the result are all of the same type.

This is a functional interface whose functional method is BiFunction.apply(java.lang.Object, java.lang.Object).
