Answer to Question #201099 in Java | JSP | JSF for Hamza

Question

The Custom Consulting Company (CCC) places temporary computer professionals in companies that request such employees. CCC’s business can be explained as follows:

CCC keeps a list of professionals willing to work or currently working on a temporary assignment. A professional may have up to three qualifications, including programmer, senior programmer, analyst, tester, designer, and so on. A company always requests a professional with a single specific qualification. CCC keeps a list of all its clients (that is, a list of other companies) and their current needs. If CCC can find a match, a professional with the required qualification is assigned to a specific opening at one of CCC’s clients.

Identify at least five classes and, for each class, list possible data members and methods.
