Assignment 2
' R& Z: z# o1 k# B% VDeadline 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)
, r% |# ^9 ~* a i! X/ G$ K5 ^! r1. 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.9 `$ }0 r) C6 } O
The staff must be able to:
( r( N I8 ^6 [+ k Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **.
8 G: v+ m; d) A8 U; D5 Y1. 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.) N- B$ R' J: T2 z
 The interface should provide a menu so that the staff can:
* q+ y1 s8 i/ m% a' Da) Enter the names of the two Java program files to be compared6 H4 V; Z* Z6 c/ R, I; }& ]
 For this assignment, it will be assumed that the two Java program files are in the same folder as your program.2 G) J0 }+ o, ~
** 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).
