This line does not compile

Files.list(Paths.get("/secret")).forEach(x -> Files.write(x, new byte[Files.size(x)]);

because Files.write() and Files.size() throw IOE. Then what's the best way to make it work?

(I find some old threads on this on lambda-dev. Maybe we have a recommended way now?)

I am not sure there is a "recommended" way. Depends on how you need to handle those exceptions, I'll put the lambda in a private function to take care those exception, and surpress them in a UncheckedIOException. Cheers, Henry
