Question
I need help solving this. Understanding Sequential Statements Summary In this lab, you complete a Java program with the provided data files. The program calculates the amount of tax withheld from an employee’s weekly salary, the tax deduction to which the employee is entitled for each dependent, and the employee’s take-home pay. The program output includes state tax withheld, federal tax withheld, dependent tax deductions, salary, and take-home pay. Instructions Ensure the file named Payroll.java is open. Variables have been declared and initialized for you as needed, the output statements have been written and the input object has been declared and initialized for you. Read the code carefully before you proceed to the next step. Write the Java code needed to perform the following: Calculate state withholding tax (stateTax) at 6.5 percent Calculate federal withholding tax (federalTax) at 28.0 percent. Calculate dependent deductions (dependentDeduction) at 2.5 percent of the employee’s salary for each dependent. Calculate total withholding (totalWithholding) as stateTax + federalTax + dependentDeduction. Calculate take-home pay (takeHomePay) as salary minus total withholding. Compile and execute your program by clicking the Run button. You should get the following output: State Tax: $81.25 Federal Tax: $350 Dependents: $62.5 Salary: $1250 Take-Home Pay: $756.25 In this program, the variables salary and numDependents are initialized with the values 1250.00 and 2. To make this program more flexible, modify it to accept interactive input for salary and numDependents.
Explanation / Answer
import java.util.Scanner;
public class Payroll {
static float stateTax = 6.5f;
static float federalTax = 28.0f;
static float dependentDeduction = 2.5f;
public float calculateStateTax(float salary)
{
return (salary*Payroll.stateTax / 100);
}
public float calculateFederalTax(float salary)
{
return (salary*Payroll.federalTax / 100);
}
public float calculateDependentDeductions(float salary, int num)
{
float total = (salary*Payroll.dependentDeduction / 100);
total *= num;
return total;
}
public static void main(String[] args) {
Payroll obj = new Payroll();
Scanner in = new Scanner(System.in);
while(true)
{
System.out.println("Enter Salary and number of dependents (press q to quit)");
String val = in.next();
if(val.equals("q"))
{
break;
}
else
{
float salary;
salary = Float.parseFloat(val);
int numDependents = in.nextInt();
float stateTax = obj.calculateStateTax(salary);
float federalTax = obj.calculateFederalTax(salary);
float dependent = obj.calculateDependentDeductions(salary, numDependents);
float totalWithholding = stateTax + federalTax + dependent;
float takeHome = (salary - totalWithholding);
System.out.println("State Tax: $"+ stateTax);
System.out.println("Federal Tax: $"+ federalTax);
System.out.println("Dependents: $"+ dependent);
System.out.println("Salary: $"+ salary);
System.out.println("Take-Home Pay: $"+ takeHome);
}
}
}
}
