Question

In Java

Kindly be sure to take in user input and store the 3 worker classes in an ArrayList

Create a class Worker. Your Worker class should include the following attributes as String variables:

Name, Worker ID, Worker Address, Worker City, Worker State

Create the constructor that initializes the above worker attributes.

Then make another class name HourlyWorker that inherits from the Worker class.   HourlyWorker has to use the inherited parent class variables and add in hourlySalary and billableHours. Your HourlyWorker class should contain a constructor that calls the constructor from the Worker class to initialize the common instance variables but also initializes the hourlySalary and billableHours. Next create a billing method to HourlyWorker that will calculate the amount due.  

FInally, create a test class that prompts the user for the information for three hourly workers (Use the scanner to input user information), creates an arraylist of 3 hourly worker objects, display the attributes and billing for each of the three hourly workers via output.. Display the worker name and billing amount for each worker and the total billing amount for all three.workers combined.

The output must be a printed version of ArrayList.

Worker.java

public class Worker {

   private String workerId, workerName, workerCity, workerState, workerAddress;

   public Worker() {
      
   }
  
   public Worker(String workerId, String workerName, String workerCity, String workerState, String workerAddress) {
       this.workerId = workerId;
       this.workerName = workerName;
       this.workerCity = workerCity;
       this.workerState = workerState;
       this.workerAddress = workerAddress;
   }

   // getters and setters used to access the private data members of the class.

   public String getWorkerId() {
       return workerId;
   }

   public void setWorkerId(String workerId) {
       this.workerId = workerId;
   }

   public String getWorkerName() {
       return workerName;
   }

   public void setWorkerName(String workerName) {
       this.workerName = workerName;
   }

   public String getWorkerCity() {
       return workerCity;
   }

   public void setWorkerCity(String workerCity) {
       this.workerCity = workerCity;
   }

   public String getWorkerState() {
       return workerState;
   }

   public void setWorkerState(String workerState) {
       this.workerState = workerState;
   }

   public String getWorkerAddress() {
       return workerAddress;
   }

   public void setWorkerAddress(String workerAddress) {
       this.workerAddress = workerAddress;
   }

   public String toString() {
       return "Worker id: " + this.workerId + ", Worker name: " + this.workerName + ", Worker Address: "
               + this.workerAddress + ", Worker City: " + this.workerCity + ", State: " + this.workerState;
   }
}

HourlyWorker.java

public class HourlyWorker extends Worker{
   private double HourlySalary, billableHours;

   public HourlyWorker() {
      
   }
  
   public HourlyWorker(String workerId, String workerName, String workerCity, String workerState,
           String workerAddress, double hourlySalary, double billableHours)
   {
       super(workerId, workerName, workerCity, workerState, workerAddress);
       this.HourlySalary = hourlySalary;
       this.billableHours = billableHours;
   }
  
   public double getAmountDue() {
       return this.HourlySalary * this.billableHours;
   }
  
   public String toString() {
      
       //super.toString() will execute the toString() method of super class that is HourlyWorker
       return super.toString() + ", Amount Due: " + this.getAmountDue();
   }
}

WorkerMain.java

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class WorkerMain {
   public static void main(String[] args) {
       Scanner in = new Scanner(System.in);
       String id, name, city, address, state;
       double hours, wagesPerHour;
      
       Worker obj = null;
       List<Worker> workers = new ArrayList<>();
      
       // read information of 3 objects
       for(int i = 0 ; i < 3 ; i++)
       {
           System.out.printf("Worker %d:\nEnter id: ", i+1);
           id = in.nextLine();
          
           System.out.print("Enter name: ");
           name = in.nextLine();
          
           System.out.print("Enter address: ");
           address = in.nextLine();
          
           System.out.print("Enter city: ");
           city = in.nextLine();
          
           System.out.print("Enter state: ");
           state = in.nextLine();
      
           System.out.print("Enter hours worked: ");
           hours = in.nextDouble();
           in.nextLine();           // clear the buffer
          
           System.out.print("Enter wages per hour: ");
           wagesPerHour = in.nextDouble();
           in.nextLine();
          
           obj = new HourlyWorker(id, name, city, state, address, wagesPerHour, hours);
           // add object to ArrayList
           workers.add(obj);
          
           System.out.println("---------------------------------");
       }
      
       // print workers information
      
       for(Worker worker: workers)
       {
           System.out.println(worker);
       }
      
       in.close();
   }
}

Output:
