- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface @API(status=STABLE, since="5.0") public interface ThrowingConsumer<T>
ThrowingConsumeris a functional interface that can be used to implement any generic block of code that consumes an argument and potentially throws a
ThrowingConsumerinterface is similar to
Consumer, except that a
ThrowingConsumercan throw any kind of exception, including checked exceptions.

ThrowingConsumerneeds to explicitly throw a
Throwable. In order to support such specialized use cases,
accept(T)is declared to throw
