Daniel Lawson Chapter 6 Project 2/1

Pseudo Code:
The program compares two text files and compares their text
    The program will first include the java.io.*, and the java.util.*,
    The program will first create a scanner which will be used for user input
    The program will first prompt the user for the name of the first fileit will ask for
    the file name until the user enters a valid file. The program will then create a scanner based off this file.
    The program will then prompt  the user for a second file, and will continue to ask for a file name until they enter a valid file name
    afterwards it will create a second scanner for the file, It will then create an additional scanner which will
    be used for reading input of the file a second time
    The program will then measure the which file is longer it will do this by calling a method which evaluates the length of a file in lines, and will compare each call to each other
    The program will run a for loop that runs equal to the lines of the larger file
     each time the program will store the next of each file and do nothing if both lines are equal.
     if they lines are unequal, then the program will print them.
