Question

In Java

#2 JAVA Write a program named salaryCalculator that accepts input from the user that represents an annual salary for employees. This program should all be written in the main driver program no additional classes are needed.

Your program should do the following:

1. Prompt the user for a salary continually until the user enters a sentinel value, a negative number.
2. Keep two running totals the first is the total of all original salaries and the second is a total of all revised salaries
3. The program should determine whether the salary is below $50000. If it is, then increase the salary by 10%
4. Output the average salary without raises and the average salary with raises.

Sample:

Enter a salary or negative number to quit: 55000

Enter a salary or negative number to quit: 52000

Enter a salary or negative number to quit: 40000

Enter a salary or negative number to quit: 30000

Average salary without raises is $44,250

Average salary with raises is $46,000

Answer 1

import java.util.*;

public class salaryCalculator
{
   public static void main(String[] args)
   {
   //scanner for input
   Scanner sc = new Scanner(System.in);
  
   //declaration of variable
   float totalWithRaise = 0, totalWithoutRaise = 0, salary;
   float avgWithRaise, avgWithoutRaise;
  
   int count = 0;
   while(true)
   {
   //display message on the computer screen
   System.out.print("Enter a salary or negative number to quit: ");
   salary = sc.nextFloat();
   if(salary<0)
   break;
  
   //calculate total without raise   
   totalWithoutRaise = totalWithoutRaise + salary;
   if(salary<50000)
   {
   salary = salary + salary * 10 / 100;
   }
  
   //calculate total with raise
   totalWithRaise = totalWithRaise + salary;
   count++;
   }
  
   //calcuate average
   avgWithoutRaise = totalWithoutRaise / count;
   avgWithRaise = totalWithRaise / count;
  
   //display the result on the computer screen
   System.out.printf("\nAverage salary without raises is $%.2f", avgWithoutRaise);
   System.out.printf("\nAverage salary with raises is $%.2f", avgWithRaise);
      
   }
}

OUTPUT:
