but only

{code }

File does not exist: /kiran

 error message should be thrown

} catch (IOException ioe) {
System.err.println("FileSystem is inaccessible due to:\n"
+ StringUtils.stringifyException(ioe));
}

i think it should use ioe.getmessage() method

} catch (IOException ioe)

{ System.err.println("FileSystem is inaccessible due to:\n" + StringUtils.stringifyException(ioe.getmessage())); } {code}
