Get Thumbs up from me. Please help. Can anyone try this? this my 5th attempt to get this solved so far noone has submitted a soulation for this. :(

Purpose Calculate payroll data using classes write complete program under one class

Upload Screenshot of output. and write a complete program under one class.

Java Topics Classes, arrays of classes, processing partial arrays, loops.

Files Used These files are in Flip_Files.zip and should be in the same folder as your program:

Employee.java Employee data tracked

EmployeeParameters.java Options used in the program

EmployeeParameters.txt The parameters for EmployeeParameters

Specification Except for the Toolkit and constants noted below, do NOT use static (global) variables. Also, all output to the output file should be echoed on the console.

Overview

Read this programs parameters of the maximum number of employees, savings rate, IRA rate, federal tax rate and state tax rate. A class, EmployeeParameters, and a method in that class are provided to read the parameter file named EmployeeParameters.txt.

Access the Employee class to see what data values will be stored.

Create an array of the Employee class of maximum number of employees

Read the input file into the Employee array. The input data is, in this order, the hours worked, the pay rate and the employee name

Calculate the gross pay for each employee based on a table.

Calculate the remaining values in the Employee class. Note that you can add variables to the Employee class if it will help write the program more efficiently and/or more easily.

Now that all the data has been calculated, print a heading and the detail lines per the spec below.

Calculate the totals of all columns, except the pay rate, which you will average.

Sort the employees alphabetically (using a provided method) and print the details the same way you did in step G above

Print the totals as in step H

Sort the employees by increasing gross pay ((using a provided method) and print the details the same way you did in step G above

Print the totals as in step H

Details follow for the main program

1. Read the Employee parameters. Access the EmployeeParameters class with, say

EmployeeParameters params = new EmployeeParameters();

The parameter class is as follows:

public class EmployeeParameters {

public int maxEmployees; // Maximum number of employees

public double savingsRate; // Savings rate as a percent

public double iraRate // IRA investment rate as a percent

public federalWithholdingRate; // Federal withholding tax rate as a percent

public stateWithholding; // State withholding tax rate as a percent

// Constructor and other methods follow. View the available methods in the class.

} // End class

Use the method in this class, getEmployeeParameters, to read the program parameters. Note that the variables in this class are declared public, not private, so you can access them from the main program. For example, after calling getEmployeeParameters, you can assign to a local variable the maximum number of employees with

maxEmployees = params.maxEmployees;

2. Use an array of a class to hold employee data. The array might be partially filled. The separate class is named Employee (in file Employee.java) and has this definition:

public class Employee {

String name; // Name of the employee

public double hoursWorked; // Hours worked in the payroll period

public double payRate; // Hourly pay rate

public double grossPay; // Gross pay based on the number of hours worked

public double adjustedGrossPay; // Gross pay less amount that goes into the IRA

public double netPay; // Gross pay less taxes

public double savingsAmount; // Amount of gross pay that goes to savings

public double iraAmount; // Amount of gross pay that goes into the IRA

public double taxAmount; // Amount of tax based on gross pay and tax rates

} // End class

You can add fields to the Employee class if it helps writing your program. In the main method, you will define an array of the above class as:

Employee[ ] empl = new Employee[maxEmployees];

where maxEmployees is a number read from the Employee Parameter file as described above in step 1. Note that this allocates space for the array but does not create instances for each employee.

Using the index i as an example, an instance of Employee can be created with a statement like:

empl[i] = new Employee();

Using the index i as an example, an instance variable can be accessed in a method with a statement like:

empl[i].netPay = empl[i].grossPay empl[i].taxAmount;

The main program should consist mostly of method calls. Use appropriate parameter passing between methods and no non-local (static) variables.

3. Data is read from a text file named YourName_S_10_Input.txt and writes to a text file named YourName_S_10_Output.txt. The input file has the employee data. Each line of employee data contains the number of hours worked, the pay rate (both doubles), followed by the name. One or more spaces separate the fields.

4. Gross pay is calculated in a separate method as follows:

hours 40.0 Paid at the pay rate.

40.0 < hours 50.0 hours > 40.0 and less 50.0 are paid at one and a half times the rate. The first 40 hours are paid at the pay rate.

50.0 < hours hours > 50.0 are paid at twice the pay rate. The first 40 hours are paid at the pay rate. Hours 40 to 50 are paid at time and a half.

Examples: with a pay rate is $10.00 an hour, gross pay is calculated as follows:

# Hours Gross Pay

30 30 x $10 = $300

40 40 x $10 = $400

46 40 x $10 + ( (46-40) x $10 x 1.5 ) = $400 + (6 x $15) = $490

50 40 x $10 + ( (50-40) x $10 x 1.5 ) = $400 + (10 x $15) = $400 + $150 = $550

58 40 x $10 + ( (50-40) x $10 x 1.5) + ( (58-50) x $10 x 2) = $400 + $150 + $160

= $710

Note how the pay rate ($10 in the example above) can be factored out, which you should do in the program. For example, the reimbursement for 46 hours is

$10 x (40 + (46-40) x 1.5) = $10 x (40 + (6 x 1.5)) = $10 x (40 + 9) = $490

Do you see why?

5. Use a method to calculate the variables for each instance of an entry in the Employee array, empl:

a. IRA amount = gross pay * IRA investment rate / 100

b. Adjusted gross pay = gross pay - IRA amount

c. Taxes = adjusted gross pay * (the sum of the tax rates as decimals)

d. Net pay = adjusted gross pay taxes

e. Savings amount = net pay * savings rate / 100

6. A method to create a report -- this method will be called after all input and all calculations are done and in turn calls three methods as follows:

a. A method to print heading information as shown in the sample output below. The information includes the report title, column headings for the name, gross pay, net pay, wealth accumulation, taxes for that employee, hours worked, and pay rate, in that order. Also shown here are the first few lines of the data in input file order and the respective totals and average that you can use to ensure you are getting the correct results. Heres how the report should look (partial list):

etc.

Totals: 14,729.71 10,502.28 2,228.60 3,049.05 1,103.14

Average: 12.36

This heading method has a parameter that indicates the print order of the data.

b. A method to print the above detail lines for all employees, matching the headings indicated in part a. Single space the detail lines. The wealth column has the sum of the savings amount and the IRA amount.

c. A method that calculates the totals for gross pay, net pay, wealth, taxes and hours, and the average(not sum) pay rate. Print a summary line with those totals and the average. (The summary line should print the totals at the bottom of the appropriate columns.) Also, print a line with a message that contains the number of employees processed which could be less than 30. You can store the totals in an array or in a separate class.

7. After the report has been printed, sort the employees alphabetically and print out the report again with the same print methods: heading, details and summary. The sort used is located in Toolkit and is called selectionSortArrayOfClass which is discussed at the end of this document and will be reviewed in class. Use the print report method described above to print the data in this order.

8. Next, sort the employees in ascending order by gross pay and print out the header, details and summary again. Use the same selectionSortArrayOfClass for the sort. Use the print report method described above to print the data in this order.

9. The Data. The input data file format is the number of hours (double), the pay rate (double) and a name (which may or may not have an initial). One or more spaces separate the fields. The file has been uploaded and is named CS1050_Assignment_10_Input.txt. Remember to trim the name once youve extracted it from the input file. The String method name is trim(). Use this data:

Using the Sort Routine in the Toolkit

Heres how to use the sort routine thats in the Toolkit. Assume the following declarations:

static Toolkit tools = new Toolkit(); // Access the Toolkit

// Assume

// sortResult is set when the sort routine is called. It is:

// 0 if the sort ended correctly

// 1 if the employee array is empty

// 2 if the sort type is not one of Name or Gross Pay

int sortResult = 0;

Employee[ ] empl = new Employee[maxEmployees];

nNames is an integer with the number of data lines read which could be less than maxEmployees.

// Some of the steps call for sorting the empl array. To sort by name:

sortResult = tools.selectionSortArrayOfClass(empl, nNames, Name);

// To sort by gross pay:

sortResult = tools.selectionSortArrayOfClass(empl, nNames, Gross Pay);
