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.
@FunctionalInterface
public interface BiConsumer<T,U>

Represents an operation that accepts two input arguments and returns no result. This is the two-arity specialization of Consumer. Unlike most other functional interfaces, BiConsumer is expected to operate via side-effects.

This is a functional interface whose functional method is accept(Object, Object).

1.8

Methods

Modifier and Type Method Description
void accept​(T t, U u)

Performs this operation on the given arguments.
default BiConsumer<T,​U> andThen​(BiConsumer<? super T,​? super U> after)

Returns a composed BiConsumer that performs, in sequence, this operation followed by the after operation.

Methods

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<? super T,​? super U> after)

Returns a composed BiConsumer that performs, in sequence, this operation followed by the after 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, the after operation will not be performed.

Parameters:
after - the operation to perform after this operation
Returns:
a composed BiConsumer that performs in sequence this operation followed by the after operation
Throws:
NullPointerException - if after is null
