Question

Write a java program to calculate a payroll payment check for the following specs:

   2.   The java program class name: Q3
      
   3.   The program should allocate constants with final data type for tax rates to include:
       (1)   local rate: 5%
       (2) state rate: 2.5%

   4.   The program accepts these data from keyboard:
       (1) employee first and last name in string format
       (2) social security number in string type variable format as: xxx-xx-xxxx
       (3) salary period in string format: Month & Year (i.e February,2017)
       (3) monthly income in integer
   5.   Calculate total tax amount, minus from annual income for net salary payment
       and O/P the calculated results in this format with one console O/P statement:

           Monthly Payroll Salary Payment Check
           ==========================================
           Employee Name:   xxxxxxxx xxxxxxxxx
           SSN: xxx-xx-xxxx

Explanation / Answer

Please find below the Q3.java class :::::

import java.util.Scanner;

public class Q3
{
   public static void main(String args[])
   {
       // declaring tax rates as constants using final data type
      
       final double local_rate = 0.05;
       final double state_rate = 0.25;
       final double federal_rate = 0.1;
       final double medical_insurance = 0.02;
        final double unemployment_insurance = 0.25;
       final double social_security_contribution = 0.05;

       Scanner sc = new Scanner(System.in);

       //Takes employee's first name

       System.out.println("Enter the Employee's first name:");
       String first_name = sc.next();

       //Takes employee's last name

       System.out.println("Enter the Employee's last name:");
       String last_name = sc.next();

       //Takes social security number in the given format

       System.out.println("Enter the Employee's social security number in the format xxx-xx-xxxx:");
       String ssn = sc.next();

       //checks if the social security number entered by the user is as per the format

       if(!((ssn.charAt(3) == '-') && (ssn.charAt(6) == '-')))
           System.out.println("Social security number entered in wrong format.");

       //Takes salary period month and year in the given format

       System.out.println("Enter the salary period in the format, Month,Year:");
       String salary_period = sc.next();

       //Takes monthly income of the employee

       System.out.println("Enter the monthly income of the employee:");
       double income = sc.nextInt();

       // Gross amount is the salary per year which is calculated by multiplying salary per month and 12(i.e no of months in a year)

       double gross_amount = income * 12;
      
       // Prints the above entered employee's details

       System.out.println("Monthly Payroll Salary Payment Check");
       System.out.println("==========================================");
       System.out.println("Employee Name: " + first_name +" " + last_name);
       System.out.println("SSN: " + ssn);
       System.out.println("salary period: " + salary_period);
       System.out.println("gross payment: " + gross_amount);

       //Calculates the tax amount payable upon the gross amount
      
       double lt = local_rate * gross_amount;
       double st = state_rate * gross_amount;
       double fr = federal_rate * gross_amount;
       double mi = medical_insurance * gross_amount;
       double ui = unemployment_insurance * gross_amount;
       double ssc = social_security_contribution * gross_amount;

       System.out.println("");
       System.out.println("");

       // Prints the above calculated various tax amounts which are payable
      
       System.out.println("Deductions: ");
       System.out.println("(1) local tax: " + lt);
       System.out.println("(2) state tax: " + st);
       System.out.println("(3) federal tax: " + fr);
       System.out.println("(4) medical insurance: " + mi);
       System.out.println("(5) unemployment insurance: " + ui);
       System.out.println("(6) social security contribution: " + ssc);
      

       double total_deduction = lt+st+fr+mi+ui+ssc;       // calculates total_deduction by adding up all the tax amounts
       double net_payment = gross_amount - total_deduction;   // calculates net_payment by subtracting total_deduction from gross salary

       System.out.println("");
       System.out.println("");

       // Prints total_deduction and net_payment as caculated above

       System.out.println("Total deduction: " + total_deduction );
       System.out.println("Net payment: "+ net_payment);

       // Ends the program      
  
       System.out.println("End of Job");
         
   }
}
