// Raad the attributes
Map<String, Object> attribs = Files.readAttributes(path, attribList);
// Display the attributes on the standard output
System.out.format("Size:%s, Last Modified Time:%s %n",
attribs.get("size"), attribs.get("lastModifiedTime"));
Listing 10-14 reads the basic file attributes of the file
C:\poems\luci1.txt
and prints some of them on
the standard output. You will need to change the file path in the
main()
method to work with another file on
your platform. You may get a different output when you run this program. If the specified file does not exist, a
NoSuchFileException
is thrown and the program prints the stack trace of the exception.
