public void setempsalary(double salary)//setter method for salary variable

}

Step-by-step explanation:

In this program we create a subclass Lecturer which inherit person class we declared a two private member in this class one is employeeNumber which is String type because string can hold integer as well as characters and second is salary which is double type then after that we create a setter method and getter method for both the variable .

for variable “employeeNumber” we create a public void setempnumber(String employeeNumber) for setter method and public int getempnumber() for getter method similarly for variable “salary” we create public void setempsalary(double salary) setter method and public double getempsalary() for getter method.
