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)
N2 n( k& F( @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.! @8 L0 q y4 c% N3 Y8 O* j
The staff must be able to:

1. The user should not be able to use the „system‟ until they have provided the correct user name and PIN combination. You should give them a second or third chance to get it right before shutting the „system‟ down. U4 C; q- M7 `% U+ N

 For this assignment, it will be assumed that the two Java program files are in the same folder as your program.: v- B, b0 S1 ^) {, s8 U
** You must use the two user names and PINs provided in your individual data available from the Assignment 2 page on Vista (see requirement 5 below). 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).
