Question

make a Pay class that had fields for a single employee's name, ID number, hourly pay, number of hours worked. use appropriate getter and setter methods, and a constructor accepting the employees name, ID number, hourly pay, and number of hours worked as arguments. The Pay class should also have a method that returns the employee's gross pay (gross pay = hourly pay* number of hours worked).

In addition include a toString method that prints to screen the employee name, ID number, hourly pay, number of hours worked, and gross pay.

Then write a program that demos the Pay class by creating a Pay object, and having user enter the data for employee.

use input valididation for what user enters. the demo program should display the name, ID number, hourly pay, number of hours worked and gross pay of the Pay object.

use java programming language

Answer 1

Explanation:I have written the classes Pay and PayDemo class which also has the main method to showsthe output of the program, please find the images attached with the answer.I have checked input validation using scanner please comment if you need any other kind of validaton.Please upvote if you liked my answer and comment if you need any modification or explanation.

//Pay class

public class Pay {
   private String employeeName;
   private int idNumber;
   private float hourlyPay;
   private float hoursWorked;

   public Pay(String employeeName, int idNumber, float hourlyPay,
           float hoursWorked) {
       super();
       this.employeeName = employeeName;
       this.idNumber = idNumber;
       this.hourlyPay = hourlyPay;
       this.hoursWorked = hoursWorked;
   }
   public String getEmployeeName() {
       return employeeName;
   }
   public void setEmployeeName(String employeeName) {
       this.employeeName = employeeName;
   }
   public int getIdNumber() {
       return idNumber;
   }
   public void setIdNumber(int idNumber) {
       this.idNumber = idNumber;
   }
   public float getHourlyPay() {
       return hourlyPay;
   }
   public void setHourlyPay(float hourlyPay) {
       this.hourlyPay = hourlyPay;
   }
   public float getHoursWorked() {
       return hoursWorked;
   }
   public void setHoursWorked(float hoursWorked) {
       this.hoursWorked = hoursWorked;
   }

   public float employeeGrossPay() {
       return hourlyPay * hoursWorked;
   }

   @Override
   public String toString() {
       return "employeeName=" + employeeName + ", idNumber=" + idNumber
               + ", hourlyPay=" + hourlyPay + ", hoursWorked=" + hoursWorked;
   }

}

//PayDemo class

import java.util.Scanner;

public class PayDemo {

   public static void main(String[] args) {

       Scanner input = new Scanner(System.in);
       String employeeName = "";
       int idNumber = -1;
       float hourlyPay = 0;
       float hoursWorked = 0;
       System.out.print("Enter name of the employee:");
       if (input.hasNext())
           employeeName = input.nextLine();
       else
           System.out.println("Invalid input for employee name");
       System.out.print("Enter ID number of the employee:");
       if (input.hasNextInt())
           idNumber = input.nextInt();
       else
           System.out.println("Invalid input for id number");
       System.out.print("Enter hourly pay of the employee:");
       if (input.hasNextFloat())
           hourlyPay = input.nextFloat();
       else
           System.out.println("Invalid input for hourly Pay");
       System.out.print("Enter the number of hours worked of employee:");
       if (input.hasNextFloat())
           hoursWorked = input.nextFloat();
       else
           System.out.println("Invalid input for hours Worked");
       Pay employeePay = new Pay(employeeName, idNumber, hourlyPay,
               hoursWorked);
       System.out.println(employeePay.toString());
       System.out.println("Gross pay: " + employeePay.employeeGrossPay());
       input.close();

   }

}

Output:
