! [, q: ?$ k* [$ Q$ ?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)* F& o* n3 ?6 y& H
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.
6 b, G8 d+ E p$ R! _1 IThe staff must be able to:
" U* [' {8 _, X9 K. f6 f Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **.+ E6 `+ R% Y, m" g _% e& R
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.. j6 O$ I X- K
 The interface should provide a menu so that the staff can:, e1 p0 J! A( [. W
a) Enter the names of the two Java program files to be compared8 V/ c t3 w8 x8 A$ v: u, x
 For this assignment, it will be assumed that the two Java program files are in the same folder as your program. k) Q; A6 U9 p. |3 B
** 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). A- P; C: a0 Z S( _! y& e
