- 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.
acceptvoid accept(T t)Performs this operation on the given argument.
t- the input argument
andThenReturns a composed
Consumerthat performs, in sequence, this operation followed by the
afteroperation. 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
afteroperation will not be performed.
after- the operation to perform after this operation
