Question

JAVA Programming .

Description:

For an unknown number of employees: prompt and receive payroll data; calculate gross pay, taxes owed, and net pay; and display a pay stub.

Input :

Prompt and receive input from the user for the following: 

/// Employee’s First and Last Name 

/// Hours Worked 

/// Pay Rate 

/// Overtime Rate Multiplier

** For the Employee’s First and Last Name:  Both data items must be read in one prompting into one variable (e.g. “Sam Jones”).  Validate to only allow alphabetic characters.  Do not validate for upper/lower case.  Re-prompt the user until the input is valid.

** For Hours Worked:  Represents the hours worked in one week.  Validate to only allow numbers in the range 0 – 100.00  Allow for up to two decimal places (e.g. 40.75).  Round to nearest cent if the user enters more than two decimal places.  Re-prompt the user until the input is valid.

** For Pay Rate:  Represents the amount earned per one hour of work.  Validate to only allow numbers in the range 9.00 – 25.00 or blank (not given).  Allow for up to two decimal places (e.g. 10.50).  Round to nearest cent if the user enters more than two decimal places.  Default value is 9.00  Dollar sign should not be entered by the user.  Re-prompt the user until the input is valid.

** For Overtime Rate Multiplier:  Represents a Pay Rate Multiplier.  Must be >= 1.0 or blank (not given).  Allow for one decimal place (e.g. 1.5).  Round if the user enters more than one decimal place.  Default value is no pay rate increase for hours > 40. In other words, hours > 40 earn wages at the same pay rate as hours <= 40. Another way of thinking of it is an overtime rate multiplier of 1.  Re-prompt the user until the input is valid. 2 v2.0 Use a While or Do-While Loop to continue prompting for employee data until a sentinel value is detected. You may not use a For-Loop. I leave the sentinel value implementation details for you to decide.

Processing:

Calculate Gross Pay as follows: 

/// Gross Pay = Hours Worked * Pay Rate 

/// If Pay Rate is not supplied, then use the default value.

/// if OverTime Multiplier is not supplied, then Gross Pay = Hours Worked * Pay Rate.

/// if OverTime Multiplier is supplied, the Gross Pay = Hours Worked (<= 40) * Pay Rate + Hours Worked (> 40) * Pay Rate * OverTime Multiplier

/// Calculate Taxes as follows:  Taxes = Gross Pay * Tax Rate 

Use the following Tax Rate Table:

Gross Pay:    Tax Rate:

<= $520    10%

> $520 and <= $680    15%

> $680 and <= $840 20%

> $840 25%

/// Calculate Net Pay as follows:  Net Pay = Gross Pay – Taxes .

Output :

After prompting, receiving and processing the data items, display the employee’s name, Gross Pay, Taxes owed, and Net Pay.

For Employee’s Name, format as proper case with only one space between the first and last names.

For Taxes, display the appropriate percentage based upon the Tax Rate Table after the word “Taxes” in the output results; for example, Taxes (15%).

Monetary values must be rounded to the nearest cent using standard rounding rules. For example, $3.409 will displayed as $3.41. $3.404 will displayed as $3.40.

Monetary values must display the dollar sign directly next to the monetary value (e.g. $304.50).

Note:

to do this, you will need to: 

Import the java.text.NumberFormat class 

Use the NumberFormat.getCurrencyInstance() method 

Use the format() method 

Do a little research for this Monetary values must be right justified.

Each employee’s information must be separated by a line of asterisks.

Answer 2

try out this code for payroll example:

public class Payrollcalc{

private:

String name;

double hoursWorked;

double hourly payRate;

static final double TAX_RATE1=0.1;//<=$520

static final double TAX_RATE2=0.15;//>$520<=680

static final double TAX_RATE3=0.2;//>680<=$840

static final double TAX_RATE4=0.4;//>$840;

public:

Payrollcalc()();

Payrollcalc(String n,double hw,double,hr)

{

this.name=n;

this.hoursworked=hw;

this.hourlyperrate=hp;

}

double grosspay(double hourlyrate,double hrsworked)

{

double grosspay=hourlyrate*hrsworked;

return grosspay;

}

double tax(double gross)

{

if(gross<=520.0) return TAX_RATE1*gross;

if(gross>520.0 && gross<=680.0)return TAX_RATE2*gross;

if(gross>680.0 && gross<=840.0) return TAX_RATE3*gross;

if(gross>840.0) return TAX_RATE4*gross;

}

String getName(){return name;}

void setName(String name){this.name=name;}

double gethoursworked(){return hoursworked;}

void sethoursworked(double hoursworked){this.hoursworked=hoursworked;}

void gethourlypayrate(){return hourlypayrate;}

void set hourlypayrate(double hourlypayrate){this.hourltpayrate=hourlypayrate;}

}

import java.util.*;

public class Payroledr

{

public static void main(String args[])

{

Scanner input=new Scanner(System.in);

Payrollcalc data=new Payrolecalc();

System.put.println("Enter your name:");

data.setname(input.next());

System.out.println("No. of hours worked:");

data.sethoursworked(Double.parseDouble(input.next());

System.out.println("Enter hourly pay rate:");

data.sethourlypayrate(Doub;e.parseDouble(input.next());

double grossamt=data.grosspay(data.gethourlypayrate().data.gethoursworked());

System.out.println("Name:"+data.getname());

System.out.println("Hoursworked"+data.gethoursworked));

System.out.println("hours pay rate"+data.gethourlypayrate());

System.out.println("grosspay"+data.grossamount());

Syste.out.println("Deductions");

System.out.println("total dedcutions $"+dada.tax(grossamount));

System.out.println("Netpay$"+grossamount-data.tax(grossamount));

input.close();}

}

HOpe this helps .please compile for any typing errors.

regards.
