Assignment 2" K% O) I7 l0 h% a4 T
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)
5 P$ T& J+ P3 M9 ?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.4 ^% `' e" K0 B# T- J
The staff must be able to:) f ?7 r+ K! l# @* B. B
 Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **.
: q6 E/ x* y7 ?8 |$ S1. 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.* C8 X1 Q- `& U; i" R, S$ A
 The interface should provide a menu so that the staff can:
! q1 a' T, M8 a, t) @* G' Qa) Enter the names of the two Java program files to be compared

' _: }1 ?" s( X7 d, _) d E1 }/ z** 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).# j! v9 B4 L7 K
