A __________ object is an object that is associated with a specific file and provides a way for the program to work with that file. a. data b. directory c. stream d. file
Write the program FileComparison that compares two files. Two files have been provided for you, Quote.txt and Quote.docx, both containing movie quotes and are located in the /root/sandbox/ directory
Note: you will not be able to see the Quote.docx file.
Next write the file comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a file’s size, you can create a System.IO.FileInfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer:
FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;
Your program's output should look like the following:
The size of the Word file is FILE_SIZE and the size of the Notepad file is FILE_SIZE The Notepad file is x% of the size of the Word file

using static System.Console;
using System.IO;

This program reads data from a physical file, create a reference to the file, perform a computation, display the result, close the file.

{
File file1 = new File("fileOne.txt"); //Create a reference to the physical file
/*
Use Notepad to create a text file named fileOne.txt
which must be in the same directory that src is in
To find src, open your project in NetBeans and hover its name, which is in
the top left just below the Projects menu; this will display the path to your project
My project path is, yours will be different

Scanner getit = new Scanner( file1 );
