Explain the isa and hasa class relationships, Computer Engineering

Assignment Help:

How would you implement each in a class design?

Ans) A specialized class "is" a specialization of another class and, thus, has the ISA relationship with the other class. An Employee ISA Person. This relationship is best executed with inheritance. Employee is derived from Person. A class may have an instance of another class. For example, an employee "has" a salary, thus the Employee class has the HASA relationship with the Salary class. This relationship is best executed by embedding an object of the Salary class in the Employee class.
