hey guys. i am working on java program which calculates taxes depend on their income. So customer inputs what is his/her status(unmarried, married so on) and then income and tax is calcualted. i have done this program with if else statemnts before(i will attache this program also) however right now i am trying to use OBJECT ORIENTED THINKING. Basycly i have one class for FederalIncomeTax.java which contains all calculations constructions, methods and so on which is needed to calculate how much tax will be for certaing amount. and second program FederalIncomeTaxClient.java which contains mainc method. so i finished everythink with FederalIncomeTax.java and when i am running it does compiles but of course not runs becuase it does not have main method. However my problem is to conncet FederalIncomeTax.java with FederalIncomeTaxClient.java. This is first time when i am trying to use two class to run one program so i have toruble. right now i will copy code which i have so far for FederalIncomeTax.java and FederalIncomeTaxClient. (I will also attache tax calculation program which i did previusly just to give you idea how it suppost to work) (i am not sure so if i have any mistake in FederalIncomeTax.java please correct me)

Thank you

import java.util.Scanner;

public class ComputeTax { public static void main(String[] args) { // Create a Scanner Scanner input = new Scanner(System.in);

// Prompt the user to enter filing status System.out.print( "(0-single filer, 1-married jointly or qualifying widow(er), " + " 2-married separately, 3-head of household) " + "Enter the filing status: "); int status = input.nextInt();

// Prompt the user to enter taxable income System.out.print("Enter the taxable income: "); double income = input.nextDouble();

// Compute tax double tax = 0;

if (status == 0) { // Compute tax for single filers if (income <= 8350) tax = income * 0.10; else if (income <= 33950) tax = 8350 * 0.10 + (income - 8350) * 0.15; else if (income <= 82250) tax = 8350 * 0.10 + (33950 - 8350) * 0.15 + (income - 33950) * 0.25; else if (income <= 171550) tax = 8350 * 0.10 + (33950 - 8350) * 0.15 + (82250 - 33950) * 0.25 + (income - 82250) * 0.28; else if (income <= 372950) tax = 8350 * 0.10 + (33950 - 8350) * 0.15 + (82250 - 33950) * 0.25 + (171550 - 82250) * 0.28 + (income - 171550) * 0.33; else tax = 8350 * 0.10 + (33950 - 8350) * 0.15 + (82250 - 33950) * 0.25 + (171550 - 82250) * 0.28 + (372950 - 171550) * 0.33 + (income - 372950) * 0.35; } else if (status == 1) { // Compute tax for married file jointly // Left as exercise } else if (status == 2) { // Compute tax for married separately // Left as exercise } else if (status == 3) { // Compute tax for head of household // Left as exercise } else { System.out.println("Error: invalid status"); System.exit(1); }

// Display the result System.out.println("Tax is " + (int)(tax * 100) / 100.0); } }
