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)
; ^- w4 Z6 E' w) V$ S1. 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.; Q) S5 t5 C# N2 D1 o- Q) O/ _/ J
The staff must be able to:
3 g9 q; E n( Y4 k5 y- ]2 R Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **.
& b# P) z/ h& j# h. e$ w1. 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.. ?* P. E, ^) _$ k& V2 r2 D
 The interface should provide a menu so that the staff can:
1 K) g5 G" h, s/ s+ P5 O7 ea) Enter the names of the two Java program files to be compared
! K* I! |; Z2 P6 _" u" ?; c For this assignment, it will be assumed that the two Java program files are in the same folder as your program.8 P( L! ~1 }: V! d4 i! y
** 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).& ]5 N5 H" k: c2 _( S, R
