Question

Employee and ProductionWorker Classes

Design a class named Employee. The class should keep the following information in fields:

-Employee name

- Employee number in the format XXX-L, where each X is a digit within the range 0-9 and the L is a letter within the range A-M

- Hire date

Write on or moe constructors and the appropriate accessor and mutator methods for the class.

Next, write a class named ProductionWorker that inherits from the Employee class. The ProductionWorker class should have fields to hold the following information:

- Shift (an integer)

- Hourly pay rate (double)

The worday is divided into two shifts: day and night. The shift field will be an interger value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the classes by writing a program that uses a ProductionWorker object.

Code superclass called Employee and subclass called ProductionWorker, and InheritanceApp as the driver class.

Use Java and please use comments to explain. Thank you!

Explanation / Answer

Employee.java

public class Employee {

   // Declaring instance variables
   private String employee_name;
   private String employee_no;
   private String hiredate;

   // Default Constructor
   public Employee() {
   }

   // Parameterized Constructor
   public Employee(String employee_name, String employee_no, String hiredate) {
       this.employee_name = employee_name;
       this.employee_no = employee_no;
       this.hiredate = hiredate;
   }

   // Setters and Getters
   public String getEmployee_name() {
       return employee_name;
   }

   public void setEmployee_name(String employee_name) {
       this.employee_name = employee_name;
   }

   public String getEmployee_no() {
       return employee_no;
   }

   public void setEmployee_no(String employee_no) {
       this.employee_no = employee_no;
   }

   public String getHiredate() {
       return hiredate;
   }

   public void setHiredate(String hiredate) {
       this.hiredate = hiredate;
   }

   // toString() method which displays the contents of an Object inside it.
   @Override
   public String toString() {
       System.out.println("Employee Name =" + employee_name);
       System.out.println("Employee No =" + employee_no);
       System.out.println("Hiredate =" + hiredate);
       return "";
   }

}

ProductionWorker.java

public class ProductionWorker extends Employee {
   // Declaring instance variables
   private double hourly_pay_rate;
   private int shift;

   // Default Constructor
   public ProductionWorker() {
       super();
   }

   // Parameterized Constructor
   public ProductionWorker(String employee_name, String employee_no,
           String hiredate, double hourly_pay_rate, int shift) {
       super(employee_name, employee_no, hiredate);
       this.hourly_pay_rate = hourly_pay_rate;
       this.shift = shift;

}

   // Setters and Getters
   public double getHourly_pay_rate() {
       return hourly_pay_rate;
   }

   public void setHourly_pay_rate(double hourly_pay_rate) {
       this.hourly_pay_rate = hourly_pay_rate;
   }

   public int getShift() {
       return shift;
   }

   public void setShift(int shift) {
       this.shift = shift;
   }

   // toString() method which displays the contents of an Object inside it.
   @Override
   public String toString() {
       super.toString();
       System.out.println("Hourly Pay Rate =" + hourly_pay_rate);
       if(getShift()==1)
       System.out.println("Shift = Day");
       else if(getShift()==2)
       System.out.println("Shift = Night");
       return "";
   }

}

Driver.java

public class Driver {

   public static void main(String[] args) {

   Employee emp=new Employee("Johnson", "123B","12-Nov-2011");
   //Displaying the Employee details
System.out.println("===== Employee Details =====");
emp.toString();

   //Creating the Production Worker Object by passing the parameters
ProductionWorker pw1=new ProductionWorker("Williams","111C","31-Dec-2014", 10, 1);

//Displaying the Production worker details
System.out.println("===== Production Worker Details =====");
pw1.toString();

   //Creating the Production Worker Object by passing the parameters
ProductionWorker pw2=new ProductionWorker("Pitersen","345H","11-Feb-2006", 15, 2);

//Displaying the Production worker details
System.out.println("===== Production Worker Details =====");
pw2.toString();

}

Output:

===== Employee Details =====
Employee Name =Johnson
Employee No =123B
Hiredate =12-Nov-2011
===== Production Worker Details =====
Employee Name =Williams
Employee No =111C
Hiredate =31-Dec-2014
Hourly Pay Rate =10.0
Shift = Day
===== Production Worker Details =====
Employee Name =Pitersen
Employee No =345H
Hiredate =11-Feb-2006
Hourly Pay Rate =15.0
Shift = Night
