Lab 6 of 7: crcs, contracts, and method specifications


Lab Overview


In this lab you will share and communicate with your fellow students to complete this lab. The instructor will assign you to a group. Within your group you can set up a group WebEx, chat, skype, or other communication tool to determine how best to complete this lab. Each person will contribute to the collaboration portion to complete this lab. Include the Names of each member on your team and a brief description as to how they participated.

Active participation is expected, but the quality, not the quantity, is the key to creating a successful collaborative learning environment for everyone. Instructional approaches for this course are highly interactive and experiential.

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.


  1. Method contract of the GetCourseByCourseID() method of the CourseList class.
  2. Method specification of the GetCourseByCourseID() method of the CourseList class.
  3. Name of each member of your team and how they participated.
