About Question enthuware.ocpjp.v8.3.1919 :

I see in the explanation, as is see on the Java 8 documentation of walk method, that are only two overloaded walk methods. How can be option three correct, because i cannot see a walk method that takes two arguments like this:

public static Stream<Path> walk(Path start, int maxDepth)

Thanks!

The method that will be used in this case is :
public static Stream<Path> walk(Path start,
int maxDepth,
FileVisitOption... options)
throws IOException

Observe that the third parameter is using the varargs format (dot dot dot), which means you can omit this parameter.

Yes, you are right. Completely understood. Thank you!
