Assignment 2
% b6 B5 a/ H' \) iDeadline 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)
8 o1 R7 T4 a3 e1 j0 D0 n1. 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.
4 ]- I0 j" x( Z4 G, v+ uThe staff must be able to:
! h$ u9 [: s+ F# e Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **.
' J- d6 g* G! z9 H1. 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.6 |4 K+ L/ ^, g7 p' E: w; e) ?

 For this assignment, it will be assumed that the two Java program files are in the same folder as your program.+ C+ |3 y) T/ e5 x, K) ^
** 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).
