Question

*****Using Java

1.         There is a class called Wages. It should have one method: calculateWages. This method accepts from a user (1) an integer hourly rate and (2) an integer total number of hours worked in a week. It calculates and displays the total weekly wage of an employee. The company pays straight time for the first 40 hours worked by an employee and times and a half for all the hours worked in excess of 40. This class should do the above for exactly three employees.

2.         There is the Java application called WagesTest. In its method main, it creates a new Wages object and calls its method, calculateWages.

Please understand the given Java source files and modify them (appropriately) for adding the following features. If you copy and paste the given code to a Notepad file, please make sure that there are no hidden special characters. You can also write your own code from scratch with the following features:

Do the following for exactly three employees:

1. Ask the user to enter the employee’s name with “Enter employee name: “

You can assume that the user will key in a one-word name, such as Bill. Use the next() method, not the nextLine() method which is complicated and can mess things up.

2. Receive the employee name keyed in by the human user.

3. Ask the user to enter whether this employee is (1) salaried or (2) paid by the hour with

“Is this employee (1) salaried or (2) paid by the hour (1 or 2 only): “

4. Receive the answer (you can assume that the user will key in either 1 or 2).

5. If this employee is salaried, then:
   • ask for his/he annual salary with “Enter the annual salary amount: “
   • receive the amount (you can assume that the user will key in a positive integer figure)
   • calculate the weekly pay amount by: annual salary / 52
   • display the calculated weekly pay amount with:

“Pay for Employee <employee name received from #2 above> is <the amount calculated here>”

6. If this employee is paid by the hour, then:
   • ask for integer hourly rate with “Enter integer hourly rate: “
   • receive the hourly rate value (you can assume that the user will key in a positive integer figure)
   • ask for integer hours worked with “Enter integer hours worked: “
   • receive the hours worked figure (you can assume that the user will key in a positive integer figure
   • if hours worked is greater than 40, then for the first 40 hours worked, calculate the normal pay with the hourly rate * 40 and for every hour over 40, calculate the overtime pay with 1.5 times the hourly rate * the extra hours over 40
   • if hours worked is not greater than 40, then calculate the normal pay with the hourly rate * the number of hours worked
   • display the calculated weekly pay amount with:

“Pay for Employee <employee name received from #2 above> is <the amount calculated here>”

import java.util.*;

class Wages // class
{
   private Scanner input = new Scanner(System.in);
  
public void calculateWages()
{
   double wage;
  
   for(int i=1;i<=3;i++)
   {
   System.out.println("Enter hourly rate : ");
   int hourlyRate = input.nextInt();
  
   System.out.println("Enter total number of hours worked in a week : ");
   int hours = input.nextInt();
  
   if(hours <= 40)
   wage = hourlyRate * hours;
   else
   wage = 40*hourlyRate + (hours-40)*hourlyRate *1.5;
   System.out.println("Wage : "+wage);
   }
}
  
}

  
class WagesTest
{
   public static void main (String[] args)
   {
       Wages w = new Wages();
       w.calculateWages();
  

   }
}

import java.util.*;

  
class WagesTest
{
   public static void main (String[] args)
   {
      
       Scanner input1 = new Scanner(System.in);
       String empName;
       double annualSalary,weeklySalary;
      
       for(int i = 1;i<=3;i++)
       {
      
       System.out.println("Enter employees's name : ");
       empName = input1.next();
  

       System.out.println("Is this employee (1) salaried or (2) paid by the hour (1 or 2 only): ");
       int option = input1.nextInt();
      
  
       switch(option)
       {
           case 1: System.out.println("Enter the annual salary amount: ");
                   annualSalary = input1.nextInt();
                   weeklySalary = annualSalary / 52;
                   System.out.println("Pay for Employee "+empName+" is "+ weeklySalary);
                   break;
          
           case 2:
      
                   System.out.println("Enter integer hourly rate: ");
                   int hourlyRate = input1.nextInt();
  
                       System.out.println("Enter total number of hours worked in a week : ");
                   int hours = input1.nextInt();
  
                   if(hours <= 40)
                   weeklySalary = hourlyRate * hours;
                   else
                   weeklySalary = 40*hourlyRate + (hours-40)*hourlyRate *1.5;

                   System.out.println("Pay for Employee "+empName+" is "+weeklySalary);
                   break;
          
           default :
                   System.out.println("Invalid option");
                   break;
       }
      
      
       }

   }
}

Output:

Enter employees's name : Bill
Is this employee (1) salaried or (2) paid by the hour (1 or 2 only): 1
Enter the annual salary amount: 72000
Pay for Employee Bill is 1384.6153846153845
Enter employees's name : Tom
Is this employee (1) salaried or (2) paid by the hour (1 or 2 only): 2
Enter integer hourly rate: 10
Enter total number of hours worked in a week : 41
Pay for Employee Tom is 415.0
Enter employees's name : Smith
Is this employee (1) salaried or (2) paid by the hour (1 or 2 only): 2
Enter integer hourly rate: 12
Enter total number of hours worked in a week : 38
Pay for Employee Smith is 456.0
