BiConsumer

  • BiConsumer is a functional interface representing an operation that takes two inputs and returns no result, primarily working through side-effects.

  • It has a functional method accept(Object, Object) which performs the operation on the provided arguments.

  • BiConsumer includes an andThen method to chain operations, enabling the sequential execution of another BiConsumer after the current one.
public interface BiConsumer

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).

Public Method Summary

abstract void
accept(T t, U u)
Performs this operation on the given arguments.
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.

Public Methods

public abstract void accept (T t, U u)

Performs this operation on the given arguments.

Parameters
t the first input argument
u the second input argument

public 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
