Question

Design two sub- classes of Employee...SalariedEmployee and HourlyEmployee. A salaried employee has an annual salary attribute. An hourly employee has an hourly pay rate attribute, an hours worked attribute, and an earnings attribute. An hourly employee that works more than 40 hours gets paid at 1.5 times their hourly pay rate. You will decide how to implement constructors, getters, setters, and any other methods that might be necessary.

1. (20 points) Draw a UML diagram for the classes.

2. (80 points) Implement the classes, and write a test program that creates a salaried employee and two hourly employees. One of the hourly employees should have hours worked set to less than 40 and one should have hours worked set to more than 40.

The test program should display all attributes for the three employees. To keep things simple, the employee classes don’t need to do any editing.

I really need help with the first part of this question regarding the UML.

Answer 1

Notes:

• Employee Class details are not provided in the question description. Hence, the details are assumed for the sake of convenient understanding and used in the UML Diagram. Please, feel free to change as per the intended needs.

Please find the UML Diagram as per the requirement:

Employee Class:

• Employee is the parent class as understood from the question.
• The variables and methods are assumed as details were not given in question.

HourlyEmployee Class:

• HourlyEmployee is the sub class.
• Hourly_Payrate is the variable to store hourly payrate.
• Hours_Worked is the variable to store number of hours worked.
• Earnings is the variable to store the gross earnings.
• SetHours() is the setter method to set Hourly_Payrate and Hours_Worked.
• GetEarnings() is the getter method to get gross earnings. This method calculates the earnings based on the number of hours worked. If >40 hours, then 1.5 times the hourly payrate.

SalariedEmployee Class:

• AnnualSalary is the variable to store the salary of the employee.
• Earnings is the variable to store the gross earnings.
• SetAnnualSalary() is the setter method to set annual salary for the employee.
• GetEarnings() is the getter method to get gross earnings.

Thank you!!!
