public String getCanonicalPath() throws IOException
Description
Returns the canonical form of this File object's pathname.
The precise definition of canonical form is system-dependent, but it
usually specifies an absolute pathname in which all relative references
and references to the current user directory have been completely
resolved. The canonical form of a pathname of a nonexistent file may
not be defined.
Exceptions
IOException
If an I/O error occurs, which is possible because
the construction of the canonical path may require filesystem queries.
