Hello, this program is done in JAVA.
Description of the Assignment
ShiftSupervisor Class:
In a particular factory, a shift supervisor is a salaried employee who supervises a shift. In addition to a salary, the shift supervisor earns a yearly bonus when his or her shift meets production goals. Design a ShiftSupervisor class that extends the Employee.java class you can download by clicking on the file name. The ShiftSupervisor class should have a field that holds the annual salary and a field that holds the annual production bonus that a shift supervisor has earned. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the class by writing a program,ShiftSupervisorDemo.java for instance, that uses a ShiftSupervisor object.
TIP: Your ShiftSupervisor class should inherit from the Employee class which you have downloaded. You will have two private fields: salary and bonus in you ShiftSupervisor class. They are both Double data type. You will also have constructors in your ShiftSupervisorclass that will call its super, Employee class's constructors accordingly. You may have tow constructors, one with parameters, one without. YourShiftSupervisorDemo.java will have a main() method. Some ShiftSupervisor objects will be created in this main() method. You ma want to display these new created ShiftSupervisor object's information.
I have completed all my code, however there is something wrong with my output.
Here is my code:
Employee.java
import java.io.*;
import java.util.Scanner;
public class Employee {
private String Empname; // Employee name
private String Empnumber; // Employee number
private String Hiredate; // Employee hire date
public Employee(String Empname, String Empnumber, String Hiredate)
{
String setName = Empname;
String setNumber = Empnumber;
String setHireDate = Hiredate;
}
public String getName()
{
return Empname;
}
public String getNumber()
{
return Empnumber;
}
public String getHireDate()
{
return Hiredate;
}
public void setName(String n)
{
Empname = n;
}
public void setNumber(String num)
{
Empnumber = num;
}
public void setHireDate(String h)
{
Hiredate = h;
}
}
ShiftSupervisor.java
class ShiftSupervisor extends Employee{
private double annualsalary;
private double annualproduction;
public ShiftSupervisor(String Empname, String Empnumber, String Hiredate, double annualsalary, double annualproduction)
{
super(Empname,Empnumber,Hiredate);
setAnuSal(annualsalary);
setAnuPro(annualproduction);
}
public double getAnuSal()
{
return annualsalary;
}
public double getAnuPro()
{
return annualproduction;
}
public void setAnuSal(double s)
{
annualsalary = s;
}
public void setAnuPro (double p)
{
annualproduction = p;
}
@Override
public String toString()
{
return "Name:"+getName()+"nEmpID:"+getNumber()+"nHire Date:"+getHireDate()+"nAnnual Salary:"+annualsalary+"nProduction"+annualproduction;
}
}
employeeDemo.java
public class employeeDemo {
public static void main (String[] args)
{
String name,id,date;
double sal,prod;
//create scanner object
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter Name:");
name=keyboard.nextLine();
System.out.println("Enter id:");
id=keyboard.nextLine();
System.out.println("Enter Hire Date:");
date=keyboard.nextLine();
System.out.println("Enter Annual:");
sal=keyboard.nextDouble();
System.out.println("Enter production:");
prod=keyboard.nextDouble();
//instantiating object
ShiftSupervisor pw =
new ShiftSupervisor(name,id,date,sal,prod);
//output data
System.out.println("Employee Details:n"+pw);
}
}//function definition
Here is my output
Notice at the end, it returns Name, EmpID, and Hire Date as "null."
Can someone please fix this for me?
