They need a simple Java program that will compare the text of two other Java programs, line by line, for equality, and then print out the results, and a recommendation. Requirements: Consider the three Java Classes: ProgramCompareMenu.java, ProgramCompare.java and AuthorisedUsers.java, available from the Assignment 2 page on Vista. You are required to perform the following tasks: The ProgramCompareMenu class: (Total maximum 20 marks available)
' L9 A6 Q$ [, v$ V1 t# ?: ?1. Provide a basic text-based menu interface to the ProgramCompare class so that it can be used by two staff members to determine if the two supplied Java programs are the same or similar.

The user names and PINs should be included in your code, and the output to the screen should prompt the user with the user names and passwords (for marking purposes).- G5 j9 e% f2 v' t* l y
