. a3 e4 F* _7 eDeadline 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)
: A( |; n$ t8 Y' T# X4 A, L1. 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." O: H1 j8 ~; g& R$ B% E! |
The staff must be able to:
- M0 I4 i D; N- H5 {% S' e4 q Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **. l) Y v- E W1 z4 w* d3 Q1 s6 W
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.
3 C& x5 l7 \0 w4 M0 J% x The interface should provide a menu so that the staff can:

 For this assignment, it will be assumed that the two Java program files are in the same folder as your program.$ M( I6 F/ X! T, L/ e7 q7 t
** 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).
