All the skills from previous Assignment(s)
Class Object and Design, including but not limited to
o Instance Variableso
Getter and Setter (including input validation in Setters)
o Constructoro Methods
Assignment Description
You will write three Class objects (and subsequently submit three .java files):
Paystub
Employee
EmployeeDriver
Class Design: Paystub
The Paystub class is intended to be an abstract and simplified representation of a paystub. A paystubwill typically contain two weeks’ data on hours worked during those two weeks.
Data to store
Hourly Rate
Make this a private instance variable with both public getter and setter Hours Worked (store this as an array of hours worked for each day of the two weeks)
o Make this a private instance variable without getter or setter (we’ll do something else)
Medical Insurance Rate ($50 – store this as a public constant) Tax Rate (30% - store this as a public constant)
Available actions
Constructor – set the hourly rate to $15/hr. by default Edit Hours – This should be a method that takes in as argument the week and day to edit as well
as the number of hours worked on that day. Be sure to check for valid input. Print Hours – This should be a method that prints out (e.g. to the console) hours worked forevery day of the two weeks. Calculate Regular Hours – A method that returns the number of regular hours worked (total)during the two weeks. Calculate Overtime Hours – Return the number of overtime hours worked (total). Print Paystub – Print out a paystub as in HW5.
Class Design: Employee
The Employee class is intended to be an abstract and simplified representation of a single employee. Anemployee typically will have several paystubs.
Data to store
Hourly rate. This should be a private instance variable with both public getter and setter.
An array of Paystub. This should be a private instance variable without getter or setter.
Available actions
Constructor – Take in as argument hourly rate of the employee and set the instance variable. Add Paystub – A method that takes in as argument a Paystub and add it to the array. Print Income History – Prints all paystubs that the employee has received so far.
Class Design: EmployeeDriver
The textbook defines a “driver program” as “A program that does nothing but test a method.” In otherwords, EmployeeDriver will be used to test the methods you implemented for the Employee class,which will result in testing both the Paystub and Employee classes, by extension.Write a main method that meets the Grading Criteria below.

output looks like
Week 1, Day 1, Hours Worked: 0.00
Week 1, Day 2, Hours Worked: 0.00
Week 1, Day 3, Hours Worked: 9.00
Week 1, Day 4, Hours Worked: 0.00
Week 1, Day 5, Hours Worked: 0.00
Week 1, Day 6, Hours Worked: 4.00
Week 1, Day 7, Hours Worked: 0.00
Week 2, Day 1, Hours Worked: 0.00
Week 2, Day 2, Hours Worked: 0.00
Week 2, Day 3, Hours Worked: 0.00
Week 2, Day 4, Hours Worked: 12.00
Week 2, Day 5, Hours Worked: 0.00
Week 2, Day 6, Hours Worked: 0.00
Week 2, Day 7, Hours Worked: 0.00
-----------------Paystub 1-----------------
Regular Hours Worked: 20.0

Explanation / Answer
Here is the code for above scenario
PayStub
package demo;
import java.util.ArrayList;
public class PayStub {
private int hourlyRate;
private int[] hoursWorked = new int[14];
public static final int medicalInsuranceRate = 50;
public static final int taxRate = 30 ;
public int getHourlyRate() {
return hourlyRate;
}
public void setHourlyRate(int hourlyRate) {
this.hourlyRate = hourlyRate;
}
PayStub(){
hourlyRate= 15;
}
public void editHours(int week, int day , int hours){
if(week>2){
System.out.println("Enter week not more than 2 ");
}
if(week<0){
System.out.println("Invalid week");
}
if(day>7){
System.out.println("Invalid day");
}
if(day<0){
System.out.println("Invalid day");
}
if(hours>24){
System.out.println("Invalid hours");
}
if(hours< 0){
System.out.println("Invalid hours");
}
if(week==1){
hoursWorked[day-1]= hours;
}
else{
hoursWorked[7+day-1]= hours;
}
}
public void printHours(){
int i;
for(i=1;i<=7;i++){
System.out.println("Week 1, Day "+i+", Hours:"+hoursWorked[i-1]);
}
for(i=1;i<=7;i++){
System.out.println("Week 2, Day "+i+", Hours:"+hoursWorked[i-1]);
}
}
public int calculateRegularHours(){
int i;
int total=0;
for(i=0;i<14;i++){
total=total+hoursWorked[i];
}
return total;
}
public int overTime(){
int i;
int total=0;
for(i=0;i<14;i++){
total=total+hoursWorked[i];
}
return total-20;
}
public void printStub(){
int i=0;
for(i=1;i<=7;i++){
System.out.println("Week 1, Day "+i+", Hours:"+hoursWorked[i-1]);
}
for(i=1;i<=7;i++){
System.out.println("Week 2, Day "+i+", Hours:"+hoursWorked[i-1]);
}
System.out.println("Regular Hours Worked:"+calculateRegularHours());
System.out.println("Overtime:"+overTime());
}
}
Employee class
package demo;
import java.util.ArrayList;
public class Employee {
private int hourlyRate;
private ArrayList<PayStub> payStubList = new ArrayList<PayStub>();
Employee(int hourlyRate){
this.hourlyRate=hourlyRate;
}
public void addPayStub(PayStub paystub){
payStubList.add(paystub);
}
public int getHourlyRate() {
return hourlyRate;
}
public void setHourlyRate(int hourlyRate) {
this.hourlyRate = hourlyRate;
}
}
