Question

Write a program that will compute the user annual salary. Prompt the user the enter (1) the weekly salary. Store the information in a double variable. Prompt the user to enter the number of weeks worked in a year. Use an int variable for that.

Write code that will compute the user's Annual salary. Gross salary is salary before any deductions are taken.

Update the code and prompt the user to enter the federal tax rate and the state's tax rate which are deducted from the weekly salary. Enter these values as percentages, without the percentage sign. Use double variables to store them. Compute and output the total taxes taken from the user's annual salary and the Net annual salary, which is the salary minus all taxes.

Update the code and prompt the user for the social security amount deducted from the weekly salary. (Assume that is less than the weekly salary). Store this information in a double variable. Compute the total annual social security amount taken from the user's annual salary and output the new net annual salary after all deductions. (Taxes and Social Security)

Update the code to compute and output the Annual deduction rate. The deduction rate is the total annual deductions taken from the salary divided by the gross annual salary. Display it as a percentage in the output.

Answer 1

Here is the code with screenshot

=======================================================================================

import java.util.Scanner;

public class AnnualSalaryCalculator {

    private static Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {

        System.out.print("Enter weekly salary: ");
        double weeklySalary = scanner.nextDouble();

        System.out.print("Enter the number of weeks worked in a year: ");
        int weeksWorked = scanner.nextInt();

        double grossSalary = weeklySalary * weeksWorked;

        System.out.print("Enter federal tax rate as percentage (without % sign): ");
        double federalTax = scanner.nextDouble();

        System.out.print("Enter state tax rate as percentage (without % sign): ");
        double stateTax = scanner.nextDouble();

        double totalTax = federalTax * 0.01 * grossSalary + stateTax * 0.01 * grossSalary;

        double netSalary = grossSalary - totalTax;

        System.out.print("Enter SSN amount deducted every week: ");
        double ssnAmount = scanner.nextDouble();

        double yearlySSNDeducted = ssnAmount * weeksWorked;

        System.out.println("Gross Salary           : $" + String.format("%20.2f", grossSalary));
        System.out.println("Annual Tax             : $" + String.format("%20.2f", totalTax));
        System.out.println("Net Salary (-Tax)      : $" + String.format("%20.2f", netSalary));
        System.out.println("Yearly SSN Deducted    : $" + String.format("%20.2f", yearlySSNDeducted));
        System.out.println("Net Salary (-Tax -SSN) : $" + String.format("%20.2f", netSalary - yearlySSNDeducted));

        double annualDeductionRate = 100.0 * (totalTax + yearlySSNDeducted) / grossSalary;
        System.out.println("Annual Deduction Rate  :  " + String.format("%19.2f", annualDeductionRate)+"%");


    }
}
