Ensure you include ALL files required to make your program compile and run.
I would like to see your .java files only.

Proper coding conventions required the first letter of the class start with a capital
letter and the first letter of each additional word start with a capital letter.
Overall Requirements

Write an employee payroll program that uses polymorphism to calculate and print the
weekly payroll for your company. There are three types of employees ─ hourly,
salaried, and salaried plus commission. Each type of employee gets paid using a
different formula. But for all employee types, if the calculated paycheck exceeds
$1000, the actual paycheck must be decreased to $1000.

Use this class hierarchy:

Employee

Hourly Salaried

SalariedPlusCommissioned

Use the public access modifier for the toString method in the Employee class and
the load method in the Employee, Hourly, Salaried, and SalariedPlusCommission
classes.
Employee.java class

Instance variables:
name
social security number
birthday month
birthday week
16
load method :
Prompts the user for instance-variable values and loads the entries.

toString method:
Returns a string that shows the employee’s name, social security number, and
paycheck.. Use the String.format method (See Java API documentation to help
you format the string as shown in the sample session’s paycheck report.) Here’s
an example from the sample session:

employee: Biff Sanchez
social security number: 111-11-1111
paycheck: $800.00

getBonus method:
Generates a $100 employee birthday bonus. Compare the employee’s birthday
with the current date found on your computer system. Use the Calendar class to
generate the current date. (See Sun’s Java API documentation.) If the employee’s
birthday month and birthday week match your computer system’s current month
and current week, then increment the employee’s paycheck by $100. The
birthdayMonth holds the month (1─12) in which the employee was born. The
birthdayWeek holds the week (1─4) that the employee chooses to get paid his/her
bonus.

Include a getEarnings method that is abstract.

Use the public access modifier for the toString method to return a string version of
the contents of the employee.
Hourly.java class

Instance variables:

hourly pay
hours worked during the past week

16
load method:
Prompts the user for instance-variable values and loads the entries.

Include a getEarnings method that calculates earnings for an hourly employee.
Hourly employees are paid by the hour. If they work more than 40 hours in a week,
then they receive overtime pay for their overtime work. Overtime pay equals one and
a half times their normal hourly pay.
Salaried.java class

Instance variables:
16

Weekly salary
load method:
Prompts the user for instance-variable values and loads the entries.

Include a getEarnings method that calculates earnings for a salaried employee.
Salaried employees are paid their fixed weekly salary regardless of the number of
hours they work.
SalariedPlusCommission.java class

Instance variables:

Sales during the past week
commission rate
16
load method:
Prompts the user for instance-variable values and loads the entries.

Include a getEarnings method that calculates earnings for a
SalariedPlusCommission employee. SalariedPlusCommission employees are paid a
base salary plus a percentage of their sales. “Percentage of their sales” equates to
the product of their sales times their commission rate.
Use initially declared named constants instead of hardcoded “magic numbers”
embedded in the program.

Provide a driver that generates the following queries and outputs.
