Question

Write a program to help a small company calculate the amount of money to pay its employees. In this simplistic world, the company has exactly three employees. However, the number of hours per employee may vary. The company will apply the same tax rate to every employee

• The program must be written in Java.
• Prompt the user for the inputs and store the values in variables
• Must include all the inputs and outputs listed here and perform the calculations correctly
  • Inputs (entered by the user of the program)
    • Name of the first employee
      • Hourly rate
      • Number of hours worked
    • Name of the second employee
      • Hourly rate
      • Number of hours worked
    • Name of the third employee
      • Hourly rate
      • Number of hours worked
    • Tax rate (between 0 and 1.0)
  • Processing and Output
    • Calculate and display the amount each employee will be paid before taxes
    • Calculate and display the amount each employee will be taxed
    • Calculate and display the amount each employee will be paid after taxes have been withheld
    • Calculate and display the total amount of taxes the company will withhold
• Make the output look attractive
• Comment your code.

You may separate the processing/calculation step from the output step or you may combine those steps. It is your choice

Java Program:

/* Java Program that calculates payroll of a company */

import java.util.Scanner;

public class Main
{
//Main method
   public static void main(String[] args) {
  
   //Scanner class object
   Scanner reader = new Scanner(System.in);
  
   //Array to hold names
   String[] names = new String[3];
  
   //Array to hold hourly rate
   double[] hourlyRate = new double[3];
  
   //Array to hold hours worked
   double[] hoursWorked = new double[3];
  
   //Reading data from User
   for(int i=0; i<3; i++)
   {
   System.out.print("\nEnter name of Employee #" + (i+1) + ": ");
   names[i] = reader.nextLine();
  
   System.out.print("Enter Hourly rate of Employee #" + (i+1) + ": ");
   hourlyRate[i] = reader.nextDouble();
  
   System.out.print("Enter Hours Worked by Employee #" + (i+1) + ": ");
   hoursWorked[i] = reader.nextDouble();
  
   reader.nextLine();
   }
  
   //Reading tax rate
   System.out.print("\n\nEnter tax rate (between 0 and 1.0): ");
   double taxRate = reader.nextDouble();
  
   double companyWithholdTax = 0.0;
  
   System.out.printf("\n %-15s %-15s %-15s %-15s \n", "Employee Name", "Pay Before Tax", "Tax Deducted", "Pay after Tax");
  
double tax, payBefore, payAfter;
  
   //Printing result
   for(int i=0; i<3; i++)
   {
//Before tax
payBefore = hoursWorked[i] * hourlyRate[i];
  
//Computing tax
tax = payBefore * taxRate;
  
//After taxRate
payAfter = payBefore - tax;
  
companyWithholdTax += tax;
  
   System.out.printf("\n %-18s %-15.2f %-15.2f %-15.2f ", names[i], payBefore, tax, payAfter);
   }
  
       System.out.printf("\n\nTotal amount of taxes company withhold: %.2f \n\n", companyWithholdTax);
   }
}
