CPSC 233: Assignment 4 (Marking Key)

    Your score Max score

Coding style (marks independent of program functionality)

    
 
  • Follows good programming conventions common to all programs (e.g., Appropriate source code white space, self documenting names, clear/simple expressions, methods implementing one task/max 30 lines of code, appropriate used of named constants): Never (0), Sometimes (4), Often (8), Mostly (12), Always (14)
   14
 
  • Follows good Object-Oriented conventions
    
    Information hiding (nested listener classes execepted): Never (0), Sometimes (1), often (2), Mostly (3), Always (4)   4
    Class attributes are logical to the definition (e.g., not variables that are just local to a method but belong to each instance): Never (0), Sometimes (2), Often (4), Mostly (6), Always (8)   8

Documentation (marks independent of program functionality)

    
  Header documentation includes full name and tutorial section   8
  Some form of versioning system is demonstrated in the header documentation   2
  Each method is documented (similar to documentation for the entire program but applies only to that method)   6
  Program limitations documented   2
  Program features documented (cut and paste out of the assignment specifications acceptable but it MUST be detailed, clear and specific...the marker must be able to know exactly what features in this marking key were actually working)   20

Functionality (only qualify for these marks if the program runs: note some features obviously requires other features to be implemented before credit will be granted)

    
  JPasswordField used to get password   2
  Can register and implement some working code for password field   4
  Can register and implement some working code for login button   4
  Password is read in from input file   4
  Password is decrypted: 'a' through 'y'   8
  Decrypts special case: 'z'   2
  Program can properly compare passwords (registers event and compares strings)   4
  Count and displays attempts   4
  Shuts down program if number of attempts exceeded   4
  Shuts down program if login dialog closed   2
  Marks for above functionality features halved if login dialog is not separate from main window    
  Main shopping window (JFrame) appears if login sucessful   8
  Can register and implement some working code for save button   4
  Can register and implement some working code for clear button   4
  Main shopping window uses GridBagLayout to handle layout   8
  Layout & alignment of controls in shopping window: Major issues (0) Minor issues (4) No issues (6)   6
  Images (using ImageIcon) for each button (2 marks each)   4
  Image (using ImageIcon) for company logo   2
  Proper labels of appropriate controls (1 mark each)   2
  Save button retrieves data of two input fields when pressed   8
  Save button changes title of frame when pressed (must be visible to user)   4
  Save button saves data to the correct file (2 marks lost if not formatted properly)   4
  Clear button clears the two input fields   8
  Shuts down program if main shopping window closed   2

Design requirements (may modify the raw functionality score)

    
 
  • Implements static methods (other than 'main()')
 Divide functionality marks by two1
 
  • Program consists of only one class (style marks will also be lost)
 Divide functionality marks by two1

GRADE POINT

 

4.0

1 These penalties are cumulative so if a program was written using only one class and was full of static methods then the student's program functionality mark would quartered.
