Create a subclass of person called lecturer that has 2 variables of its own: employeenumber and salary. as in the above scenario, these variables should be declared private with the appropriate getter and setter methods to access them.

Following are the class is given below

public class Lecturer  extends Person  

{

private String employeeNumber;// private variable

private double salary;  // private variable

public String getempnumber() // getter method for employeeNumber  

{

return employeeNumber;

}

public void setempnumber(String employeeNumber) // setter method for  employeeNumber variable  

{

this.employeeNumber = employeeNumber;

}

public double getempsalary() //getter method for  salary variable  

{

{

return salary;

}

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

{

this.salary = salary;

}

}

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.
