File Objects
A File object
holds information about
a disk file or a disk directory
and methods to manipulate them.
A File object
is NOT the actual file.
It does not contain the data that the file holds.
It is an object that holds
methods that affect a particular file or directory.
It works as an interface between a program and
the functions of the operating system that
do the actual file manipulation.
Different operating systems
organize their file systems in different ways.
By using a File object,
a Java program
is isolated from the details of how the operating system handles files.
The program can use File methods
to manipulate files, and the File object handles the details.
If a File object and a file are separate things,
is it possible:
File object to exist without a file?File object?
