Use Java Please

File 1 and File 2 at bottom of post.

1. Write a program that compares two text files for equality. Print out any lines that are different along with the line number.

2. Include the following:

  • File I/O Exception Handling using a Try/Catch Block
  • Algorithm: Initial and Refined
  • Internal Documentation
  • All prologue information
  • The two external files

3. Use the following two files: File1.txt and File2.txt. These files are included. I have also attached zip files containing them because sometimes the files are converted to HTML files when downloaded.

4. Zip and Submit the program along with the two files you used for the comparison.

NOTE 1:  You may be tempted to use other means of processing File I/O that you come across on the internet.  DO NOT USE any other means of processing files other than what is introduced in the lectures. Any program that uses something different will result in a grade of 0.  NO EXCEPTIONS.

NOTE 2:
1. Declare all variables within the data declaration section of each class and method.  
2   Do not get input on the same line as a variable declaration.
3. Do not place an equation for computation on the same line as declaring a variable.
