<U>
the type of the second argument to the operation
Imports
java.util.Objects
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 void
accept(T
the first input argument
t, U
the second input argument
u)

Performs this operation on the given arguments.

public default BiConsumer<T, U>

Returns:

a composed BiConsumer that performs in sequence this operation followed by the after operation
andThen(BiConsumer<? super T, ? super U>
the operation to perform after this operation
after)

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

Method Detail

public void accept(T t, U u)

Performs this operation on the given arguments.

Parameters
t:T

the first input argument

u:U

the second input argument

andThenback to summary
public 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:BiConsumer<? super T, ? super U>

the operation to perform after this operation

Returns:BiConsumer<T, U>

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

Exceptions
NullPointerException:
if after is null
