Summary:

For assignment one you will be implementing a payroll system that allows you:

1) Populate Employees

a.You should populate one of each of the following employees in your collection:

i.Hourly Employee

1. Prompt for Hours

2. Prompt for Rate

3. Make sure to calculate for overtime at time and a half

ii.Salary Employee

1. Prompt for Staff or Executive

2. Set Gross salary to $50,000 for staff and $100,000 for executives

iii.Commission Employee

1. Prompt for number of items sold

2. Prompt for unit price of item sold (we are selling widgets so just set a price of your choosing)

3. Commission Employees will get 50% of gross sales

2) Select Employee

a. Loop through your array and select the employee

b. Once the employee is selected you will get a menu inside of each Employee that allows you to select the following

i. Calculate Gross Pay

ii. Calculate Tax

iii. Calculate Net Pay

iv. Calculate Net Percent

v. Display Employee

3) Save Employees

a. Save the array or collection of Employees as a serialized object

b. Additionally you will save a file/report of each employee as a text file

4) Load Employee

a. You will load back in the serialized objects from the saved file

b. You should use a boolean variable that is set to true if you have loaded employees

i.This in turn would inform users and prevent them from populating employees if they select that option

Structure of Project:

- You are given the code below for your Employee Object.

- Each employee (Hourly, Salary, Commission) should inherit from Employee

- You will need to figure out which method from Employee that you should override in each subclass. ( It will only be one method)

- Payroll Class will have:

-Main method

-Menu method

-Populate Employees method

-Select Employee method

-Save Employee method

-Load Employee method

Employee Class will have:

-Code Given Below

EMPLOYEE CODE:

public class Employee
