Question

Write a Java program that calculates and prints the monthly pay check for an employee. The net pay is calculated after taking the following deductions:
Federal Income Tax: 15%
State Tax: 3.5%
Social Security Tax: 5.75%
Medicare/Medicaid Tax: 2.75%
Pension Plan: 5%
Health Insurance: $75.00

Your program should prompt the user to input the employee name and the gross amount. The out put will be stored in a file. Format your output to two decimal places. A sample output follows.

Gross Amount: $3575.00
Federal Tax: $536.25
State Tax: $125.13
Social Security Tax: $205.56
Medicare/Medicaid Tax: $98.31
Pension Plan: $178.75
Health Insurance: $75.00
Net Pay: $2356.00

Answer 1

Answer:

import java.io.FileWriter;

import java.util.Scanner;

public class PayCheck {

public static void main(String[] args) {

 // Create an object of the Scanner class to allow for user's input

 // via the  keyboard.

 Scanner input = new Scanner(System.in);

 // Prompt the user to enter employee's name

 System.out.println("Please enter employee's name");

 // Store the user's input in a String variable called name.

 String name = input.nextLine();

 // Prompt the user to enter the gross amount

 System.out.println("Please enter the gross amount (in dollars)");

 // Store the user's input in a double variable called amount.

 double amount = input.nextDouble();

 // Calculate the Federal Income Tax

 double FIT = 15 / 100.0 * amount;

 // Calculate the State Tax

 double ST = 3.5 / 100.0 * amount;

 // Calculate the Social Security Tax

 double SST = 5.75 / 100.0 * amount;

 // Calculate the Medicare/Medicaid Tax

 double MT = 2.75 / 100.0 * amount;

 // Calculate Pension Plan

 double PP = 5 / 100.0 * amount;

 // Calculate the Health Insurance;

 double HI = 75.00;

 // Calculate total pay to be deducted from actual pay

 double TOTAL = FIT + ST + SST + MT + PP + HI;

 // Calculate the net pay

 double NETPAY = amount - TOTAL;

 // Format the result using String.format() to print out the details of

 // the employee plus the amount paid in two decimal places

 // Store the result of the formatting in a String variable, paydetails.

 String paydetails = String.format("%s%.2f\n", "Gross Amount: $", amount);

 paydetails += String.format("%s%.2f\n", "Federal Tax: $", FIT);

 paydetails += String.format("%s%.2f\n", "State Tax: $", ST);

 paydetails += String.format("%s%.2f\n", "Social Security Tax: $", SST);

 paydetails += String.format("%s%.2f\n", "Medicare/Medicaid Tax: $", MT);

 paydetails += String.format("%s%.2f\n", "Pension Plan: $", PP);

 paydetails += String.format("%s%.2f\n", "Health Insurance: $", HI);

 paydetails += String.format("%s%.2f\n", "Net Pay: $", NETPAY);

 // Print out the result to the console

 System.out.println(paydetails);

 // You could also write the output to a file named document4.txt

 //  using the  FileWriter class.

 try {

  FileWriter fwriter = new FileWriter("document4.txt");

  fwriter.write(paydetails);

  System.out.println("Written to file");

  fwriter.close();

 } catch (Exception e) {

  e.printStackTrace();

 }

}

}
