Scenario Summary: The Design Phase Of The SRS Project 065550

Scenariosummarythe Design Phase Of The Srs Project Is In Full Swing A

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 to pick a course from a list of courses. 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, the course object is returned by the GetCourseByCourseID() method; otherwise a null value is returned, indicating there are no matching courses. Deliverables Method contract of the GetCourseByCourseID() method of the CourseList class Method specification of the GetCourseByCourseID() method of the CourseList class Must be in Visual Basic Must be in Structured English not pseudocode.

Method Contract of GetCourseByCourseID

The method GetCourseByCourseID in the CourseList class is designed to retrieve a course object that matches a specified course ID from the current list of courses. The contract specifies the method's interface, including its name, parameters, return type, and behavior. It guarantees that when a valid course ID is provided, it will return the corresponding Course object, if such a course exists; otherwise, it will return null, indicating no match was found. This contract helps ensure consistent interaction and clear expectations between the method and its callers.

Method Specification of GetCourseByCourseID in Structured English (Visual Basic style)

Function GetCourseByCourseID(CourseID As String) As Course


' Iterate through each course in the current course list


For Each course As Course In CourseList


' Check if the current course's ID matches the provided CourseID


If course.CourseID = CourseID Then


' A match is found; return the course object


Return course


End If


Next


' No matching course found; return null


Return Nothing


End Function

Explanation:

  • The method takes a single parameter, CourseID, of type String, which represents the identifier of the course to be searched.
  • The method returns an object of type Course. If a course with the specified ID exists, it returns the Course object; if not, it returns null (Nothing in Visual Basic).
  • The search process involves looping through the list of courses stored in the CourseList collection.
  • Each course's CourseID property is compared with the input parameter.
  • If a match is found, the method returns the corresponding Course object immediately.
  • If no match is found after completing the loop, the method returns null.
