Deadline for Submission: 10:00 pm (Shanghai time), Tuesday 15th May 2007 Assessment Weighting: 20% of the total assessment for BSA104 Assignment Type: Individual Scenario: The teaching staff at a nearby university are concerned that some of their students are submitting other students‟ work. 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)
