Question

**JAVA LANGUAGE**

This assignment will use the Employee class that you developed for assignment 6. Design two sub- classes of Employee...FullTimeEmployee and HourlyEmployee. A full-time employee has an annual salary attribute and may elect to receive life insurance. An hourly employee has an hourly pay rate attribute, an hours worked attribute for the current pay period, a total hours worked attribute for the current year, a current earnings attribute (for current pay period), a cumulative earnings attribute (for the current year), and can work a maximum of 980 hours per year. An hourly employee that works more than 40 hours in a pay period 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. Draw a UML diagram for the classes and show all attributes and methods.

2. Implement the classes and write a test program that creates two full-time employees and two hourly employees. One of the full-time employees should elect the life insurance option. 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.
