Question

Purpose: Build an application to calculate an Employee’s Gross Pay and a Department’s Average Pay Report

Requirements: Build an application to allow the end-user to calculate an Employee’s Gross Pay and the Department’s average Gross Pay Report. First, the user will enter each employee’s name, hours worked and hourly pay rate into parallel arrays. Then the application calculates and displays each Employee’s Full Name and Payroll Information (see both inputs and outputs listed in the tables below).  

Assumptions:

1. Assume your department has 10 employees (or less).  

2. Gross Pay = (Regular hours* pay rate) + (Over Time hours * pay rate *1.5) a. Regular hours are less than or equal to 40 Language: JAVA Techniques: Your successful program will implement the following program techniques: 1. Arrays and Array Processing – (Arrays will hold employee information) 2. Methods – (Most of your process should be in methods)

3. Decisions – (Enter only hours worked – Your application calculates regular and overtime hours)

4. Loops – (For processing each employee)

Explanation / Answer

import java.util.Scanner;

// Class GrossPay definition

public class GrossPay

{

// Instance variables to store employee information

String firstName;

String lastName;

double regularHours;

double overtimeHours;

double payRate;

double grossPay;

// Constructor to initialize instance variables

GrossPay()

{

firstName = lastName = "";

regularHours = overtimeHours = payRate = grossPay = 0.0;

}// End of constructor

// Method to accept employee data

void acceptData()

{

// Scanner class object created

Scanner sc = new Scanner(System.in);

// Accepts employee data from the user

System.out.println("Enter Employee’s First Name: ");

firstName = sc.next();

System.out.println("Enter Employee’s Last Name: ");

firstName = sc.next();

System.out.println("Enter Regular Hours: ");

regularHours = sc.nextDouble();

System.out.println("Enter Overtime Hours: ");

overtimeHours = sc.nextDouble();

System.out.println("Enter Pay Rate: ");

payRate = sc.nextDouble();

}// End of method

// Method to calculate gross pay

void processData()

{

grossPay = (regularHours * payRate) + (overtimeHours * payRate * 1.5);

}// End of method

// Method to display employees gross pay

void displayData()

{

System.out.println("Employee’s Full Name: " + firstName + " " + lastName);

System.out.println("Regular Hours: " + regularHours);

System.out.println("Overtime Hours: " + overtimeHours);

System.out.println("Pay Rate: " + payRate);

System.out.println("Employee’s Gross Pay: " + grossPay);

}// End of method

// main method definition

public static void main(String[] args)

{

// Initializes local variable to zero

double departmentAvgPay = 0.0;

// Creates an array of objects of class GrossPay of size 10

GrossPay gp[] = new GrossPay[10];

// Loops 10 times

for(int x = 0; x < 10; x++)

{

// Creates an object

gp[x] = new GrossPay();

// Calls the method to accept employees data

gp[x].acceptData();

// Calls the method to calculate employees gross salary

gp[x].processData();

// Calculates departments total pay

departmentAvgPay += gp[x].grossPay;

}// End of for loop

// Loops 10 times

for(int x = 0; x < 10; x++)

gp[x].displayData();

// Displays department average pay

System.out.println("Department Ave Pay: " + (departmentAvgPay / 10));

}// End of main method

}// End of class
