- Type Parameters:
- T- the type of the operands and result of the operator
 - All Superinterfaces:
- BiFunction<T,T,T>
 - 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 BinaryOperator<T> extends BiFunction<T,T,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 ofBiFunctionfor 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(Object, Object).- Since:
