- 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 Consumer<T>
Represents an operation that accepts a single input argument and returns no result. Unlike most other functional interfaces,Consumeris expected to operate via side-effects.This is a functional interface whose functional method is

Performs this operation on the given argument.- Parameters:
t- the input argument
-
andThen
default Consumer<T> andThen(Consumer<? super T> after)
Returns a composedConsumerthat performs, in sequence, this operation followed by theafteroperation.

If performing this operation throws an exception, theafteroperation will not be performed.- Parameters:
after- the operation to perform after this operation- Returns:
