SE 3M04 T1 2002
Assignment 3a - Final Version (Sun. Oct 20)

• Due: Tuesday October 29, 20:00 through WebCT
• Goals:
  • Learn more about testing and requirements
• Build a Java program that constructs mathematical expressions for systems of simple equations
• The program should be designed so that it passes all the tests given in this zip file. Note that in ca/mcmaster/se3m04 are definitions of 2 interfaces that must also be used.
• Reverse engineer the specifications from the tests (and your code). Use javadoc to properly document the specifictions.
• Deliverables:
  1. Specification document (ie javadoc output for the classes, including at least a comment for each class, method and argument of each method, each field, etc). Use comments to specify any additional formula(s) that should hold true.
  2. Java program which passes all the tests.
  3. electronic copy of log
• Hints:
  • Read *all* of the tests carefully first. They embody all of the requirements.
  • Work incrementally. First comment out most of the tests, and build your program to pass a few of them. Start with the earlier tests first.
  • Build your module (ie class hierarchy) skeleton early. In Java, this can be done by declaring your classes but having no methods in them.
