Answer Posted / meziane
The list() of the class java.io.File "returns an array of Strings naming the files and directories in the directory denoted by this abstract pathname."
http://docs.oracle.com/javase/6/docs/api/java/io/File.html#list%28%29
The abstract pathname is the path specified in File f = new File(patAsString).
The method returns null, if the abstract pathname does not denote a directory (i.e an existing directory).
No compilation error.
