Assignment 2
2 E2 q: z8 p7 Q+ ~( b- KDeadline 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)+ W* n1 J3 L' b b" ~& n
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.
$ b5 q* I& Q7 l; hThe staff must be able to:
* p( w& r) L( `# p! R0 K Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **.
; @ _: S. Q4 d3 N$ D1. 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.% X* m6 _2 i/ N! ?
 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.+ z$ F+ n' n% W
** 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).+ I5 M U ]5 m u3 O! T
