The program takes a file name from the user as a command line argument. It then displays information about the given file including whether it exists, is readable and writable, its type (file or directory), and its length in bytes. The File class and its methods like getName(), getPath(), length(), canRead(), canWrite(), isDirectory(), isFile() are used to retrieve and display this information about the given file.
