Answer 1

If your communication is with a FTP Server I this link will help you: http://www.codejava.net/java-se/networking/ftp/determine-if-a-directory-or-file-exists-on-ftp-server

PS: For some reason the website is not allowing me to add a comment so posted in the answer section. Not sure if this answers your question.

Answer 2

Your URI is not absolute. See RFC 3986 Section 4.3. Absolute URI

Also see https://docs.oracle.com/javase/8/docs/api/java/net/URI.html

An absolute URI specifies a scheme; a URI that is not absolute is said to be relative.

You need to provide a scheme like http , ftp or other.
