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).
Consumer| 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  BiConsumerthat performs, in sequence, this
 operation followed by theafteroperation. | 
void accept(T t, U u)
t - the first input argumentu - the second input argumentdefault BiConsumer<T,U> andThen(BiConsumer<? super T,? super U> after)
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.after - the operation to perform after this operationBiConsumer that performs in sequence this
 operation followed by the after operationNullPointerException - if after is null Submit a bug or feature
