Question

Write a java program that calculates the total amount of money a person has made over the last year. The program will prompt the user for dollar amounts showing how much the user has made per job. Some users will have had more than one job, make sure your program allows for this. The program will print out the total made (all jobs) and will print out the federal and state taxes based on the total made. For this program, the federal tax will be 8.5% and the state tax will be 14.5%.

1. Use appropriate comments throughout the program. ***PLEASE BE AS DETAILED AS POSSIBLE TO UNDERSTAND CODE FORMAT***
2. Create a header at the top showing the programmer, date of creation and class.
3. Make sure you insert appropriate instructions for the user.

Answer 1

import java.util.Scanner;

public class Jobs {
   public static final double FEDERAL_TAX=8.5;
   public static final double STATE_TAX=14.5;
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       int i=1;
       double n,gross=0;
       //reading the salaries for all jobs from user
       //adding to sum of the incomes
       while(true) {
           System.out.println("How much income you made through job "+i+"(-1 to quit)");
           n=sc.nextDouble();
           i++;
           if(n==-1)
               break;
           gross+=n;
          
       }
      
       double federalTax=getTax(gross,FEDERAL_TAX);
       double stateTax=getTax(gross, STATE_TAX);
       double net=gross-federalTax-stateTax;
       System.out.println("Gross : "+gross);
       System.out.println("Federal Tax : "+federalTax);
       System.out.println("State Tax: "+stateTax);
       System.out.println("Net : "+net);
      
   }
   //returns the tax on given amount with given percentage
   private static double getTax(double n, double tax) {
       return n * (tax/100);
   }
}
