Explain the ISA and HASA class relationships. How would you implement each in a class design?

A specialized class "is" a specialization of another class and,

therefore, has the ISA

relationship with the other class. An Employee ISA Person. This relationship is

best

implemented with inheritance. Employee is derived from Person. A class may have

an instance of another class. For example, an employee "has" a

salary, therefore the

Employee class has the HASA relationship with the Salary class. This

relationship is

best implemented by embedding an object of the Salary class in the Employee

class.
