Assignment 2
1 I" W7 y, g6 H% H5 ]6 y* }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 W* r- l: ^ k7 O w
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 [/ }" x! B0 p; R6 C
The staff must be able to:
' q0 |3 u3 X- G$ N" Z6 Z6 F' ]6 v5 r Log on to the „system‟ using their user name, and a Personal Identification Number (PIN) which is a four digit number **.
5 D: w1 A9 i- j, K2 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.0 ?7 e& S+ W* T4 B
 The interface should provide a menu so that the staff can:
; z# _ Z- a$ o4 a& f7 ?- ya) Enter the names of the two Java program files to be compared. c1 T/ K9 x. E
 For this assignment, it will be assumed that the two Java program files are in the same folder as your program.
" u) P- Y- e7 L- H** 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).
