The design phase of the SRS project is in full swing and every
developer on the team is assigned a group of packages to work on and to
complete the design details of the classes in the package. To help speed up the
design process, you—as the software architect of the project—were assigned the
task of providing a sample
method contract and a sample method specification to demonstrate to
your team how these two documents are developed.
You decided to use the CourseList and the Course classes for your
demonstrations. The CourseList class maintains and populates the current list
of courses that the end user is working with while registering for clases. You
will demonstrate the contract and the specification of the
GetCourseByCourseID() of the CourseList class.
The GetCourseByCourseID() method searches the current list of courses
for a course whose CourseID matches the ID supplied to the method. If a matched
course is found, it is returned by the GetCourseByCourseID() method; otherwise
a null value is returned, indicating there are no matching courses.

STEP 1:
Create a Public Method Contract
Download the CRC Cards for the CourseList and Course classes and
review them to prepare for your deliverables this week. Download the Method
Contract Template and use it for your deliverables this week. Create the method
contract for the GetCourseByCourseID() method of the CourseList class. Explain
your work and the decisions you made to arrive at your proposed solution.
STEP 2:
Create a Method Specification
Download the Method Specification Template and use it for your
deliverables this week. Create the method specification for the
GetCourseByCourseID() method of the CourseList class. Explain your work and the
decisions you made to arrive at your proposed solution.
