(b) The class diagram below shows the relation of three classes of a program. The class Employee is a superclass of two derived classes, Operator and Executive. Employee countEmp: int -name: string ID: int + Employee (name :string, ID:int) +getName (): string +getID () :int +getCount () : int Operator Executive +Executive (name :string, ID:int) -hour: double +Operator (name:string, ID:int) +setHour (hour:double) :void +getHour () : double +computeSalary () :double The member methods of class Employee: Operator (name :string, ID:int) : Overloaded constructor. This constructor initializes the member attributes and increases the static variable countEmp by 1. getName () : This function returns the value of member attribute name. getID () : This function returns the value of member attribute ID. getCount () : This function returns the value of member attribute countEmp. The member methods of class Operator: Circle (name:string, ID:int): Overloaded constructor. This constructor initializes the superclass's member attributes by calling the constructor of superclass Employee. It will then displays text "Operator name_of_operator created!". setHour (hour:double) : This function sets the value of member attribute hour. getHour () : This function returns the value of member attribute hour.
