Interface BiConsumer<T,​U>

  • Type Parameters:
    T - the type of the first argument to the operation
    U - the type of the second argument to the operation
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterfacepublic interfaceBiConsumer<T,​U>
    Represents an operation that accepts two input arguments and returns no result. This is the two-arity specialization ofConsumer. Unlike most other functional interfaces,BiConsumer is expected to operate via side-effects.

    This is afunctional interface whose functional method isaccept(Object, Object).

    • Method Detail

      • accept

        void accept​(T t,U u)
        Performs this operation on the given arguments.
        Parameters:
        t - the first input argument
        u - the second input argument

      • andThen

        default BiConsumer<T,​U> andThen​(BiConsumer<? superT,​? superU> after)
        Returns a composedBiConsumer that performs, in sequence, this operation followed by theafter operation. If performing either operation throws an exception, it is relayed to the caller of the composed operation. If performing this operation throws an exception, theafter operation will not be performed.
        Parameters:
        after - the operation to perform after this operation
        Returns:
        a composedBiConsumer that performs in sequence this operation followed by theafter operation
        Throws:
        NullPointerException - ifafter is null
