Question

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.

Answer 1

Answer:

// Payroll.java

public class Payroll

{

int numOfDependents;

double salary;

double salaryToHome;

double Federal_Tax,TAX_RATE,Depen_tax;

 

Payroll(double salry,int nod)

{

numOfDependents=nod;

salary=salry;

Federal_Tax=6.5;

TAX_RATE=28.0;

Depen_tax=2.5;

}

 

double getTAX_RATE()

{

return TAX_RATE*salary/100;

}

double Federal_Tax()

{

return Federal_Tax*salary/100;

}

double getDepenAmount()

{

return numOfDependents*(Depen_tax*salary/100);

}

double getTakeHomeSalary()

{

return salary+getDepenAmount()-(getTAX_RATE()+Federal_Tax());

}

void printOutput()

{

System.out.print("\nState Tax: $"+getTAX_RATE());

System.out.print("\nFederal Tax: $"+Federal_Tax());

System.out.print("\nDependents: $"+getDepenAmount());

System.out.print("\nSalary: $"+salary);

System.out.println("\nTake Home Pay: $"+getTakeHomeSalary());

 

}

public static void main(String args[])

{

Payroll obj=new Payroll(1250,2);

obj.printOutput();

}

}

// ModifiedPayroll.java

import java.util.Scanner;

public class ModifiedPayroll

{

 

int numOfDependents;

double salary;

double salaryToHome;

double Federal_Tax,TAX_RATE,Depen_tax;

 

ModifiedPayroll(double salry,int nod)

{

//initialise variables

numOfDependents=nod;

salary=salry;

Federal_Tax=6.5;

TAX_RATE=28.0;

Depen_tax=2.5;

}

 

double getTAX_RATE()

{

return TAX_RATE*salary/100;

}

double Federal_Tax()

{

return Federal_Tax*salary/100;

}

double getDepenAmount()

{

return numOfDependents*(Depen_tax*salary/100);

}

double getTakeHomeSalary()

{

return salary+getDepenAmount()-(getTAX_RATE()+Federal_Tax());

}

void printOutput()

{

System.out.print("\nState Tax: $"+getTAX_RATE());

System.out.print("\nFederal Tax: $"+Federal_Tax());

System.out.print("\nDependents: $"+getDepenAmount());

System.out.print("\nSalary: $"+salary);

System.out.println("\nTake Home Pay: $"+getTakeHomeSalary());

 

}

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("\nEnter Salary: $");

double salary=sc.nextDouble();

System.out.print("\nEnter number Of Dependents:$");

int nob=sc.nextInt();

ModifiedPayroll obj=new ModifiedPayroll(salary,nob);

obj.printOutput();

}

}

Output:

// For Payroll.java

State Tax: $350.0

Federal Tax: $81.25

Dependents: $62.5

Salary: $1250.0

Take Home Pay: $881.25

// For ModifiedPayroll.java

Enter Salary:$1550.0

Enter number of Dependents:$3

State Tax: $434.0

Federal Tax: $100.75

Dependents: $116.25

Salary: $1550.0

Take Home Pay: $1131.5
