Employee Payroll Management

E MPLOYEE C LASS C HANGES:

$1.$ Add unique identifier to Employee class:

o Change ID to be $8-$digit String that is an auto$-$generated UUID

$2.$ Change Name instance variable to be First Name and Last Name as

separate variables

o Update constructors

o Add getters and setters for FirstName and LastName

o Update getName method to return $$FirstName LastName$$

$3.$ Change Employee class to be abstract

o Add one abstract method $$ double pay$()$;

$4.$ Remove print$()$ method

$5.$ Add toString, equals, and hashCode methods

N EW C LASSES:

$1.$ Add Hourly Employee class that is a subclass of Employee

o Add instance variable Pay Rate as a double

o Add instance variable Number Hours Worked as a double

o Add these to the constructors and add getters and setters

$2.$ Add Salary Employee class that is a subclass of Employee

o Add instance variable Annual Salary as a double

o Add this variable to the constructors and add getter and setter

$3.$ Implement abstract method pay in each employee subclass to calculate and

return the employees weekly pay amount:

o HourlyEmployee $=$ pay rate $*$ number hours worked

o SalaryEmployee $=$ annual salary $/$ number weeks in year

R EQUIREMENTS:

$$ All classes should have the following methods:

o Default constructor with no arguments

o Constructor with all fields

o Getters & Setters for all instance variables except no setId method

o toString, equals, and hashCode methods

$$ Classes must be named Employee, HourlyEmployee, SalaryEmployee in the

unex.hr package

$$ Demo class must be called EmployeeDemo in the unex.hw package

D EMO R EQUIREMENTS:

Write a demonstration program that will create multiple employees and store

them in an ArrayList.

$$ Create multiple instances of each employee type and store in ArrayList

$$ Print out all employees

$$ Pay all employees and print out a list of employees and their pay.

Include the total payroll amount for the week.

$$ Use NumberFormat to format the pay amount as currency.

T IPS & H INTS:

$$ Store constants as static variables, such as number of weeks in year.

$$ You do not need to do user input. You can just create objects in your demo.

$$ Create at least $5$ employees and make sure to store them in an ArrayList
