first, is considered to be a sequence of name elements (see
Path) and is joined to form a path string. The details as to how the Strings are joined is provider specific but typically they will be joined using the

Note that while this method is very convenient, using it will imply
an assumed reference to the default
FileSystem and limit the
utility of the calling code. Hence it should not be used in library code
intended for flexible reuse. A more flexible alternative is to use an
Path instance as an anchor, such as:
Path dir = ... Path path = dir.resolve("file");

FileSystemNotFoundException- The file system, identified by the URI, does not exist and cannot be created automatically, or the provider identified by the URI's scheme component is not installed
