Answer 1

An abstract pathname is a java.io.File object and a pathname string is a java.lang.String object. Both reference the same file on the disk.

The first sentence of the Javadoc of java.io.File explains:

An abstract representation of file and directory pathnames.

It goes on to explain why:

User interfaces and operating systems use system-dependent pathname strings to name files and directories. This class presents an abstract, system-independent view of hierarchical pathnames.
