Question

use java

You are asked to create a record management system for a university.

There are two type of employees in a university:

• Salaried employee: they are salaried, and they are paid by monthly salary
• Waged employee: they are on wage and paid biweekly

You are asked to implement three classes: Employee, SalariedEmployee and WagedEmployee.

We have the following properties, and you need to identify these properties and associate them with appropriate classes.

• name: name of the employee
• ssn: ssn of the employee
• salary: yearly salary of the employee
• hourRate: base rate for the employee per hour
• overTimeRate = 1.5: when the employee work overtime, the employee will be paid at base rate times over time rate.

and the following methods (make sure that you associate each method with the appropriate class):

• get and set methods for each data field (except fields specified as final)
• getYealyBasePay(): this method compute and returns the yearly pay of an employee if he/she works full time(40 hours per week) with no over time. Both types of employee should have this method.
• getBiWeeklyPay(int hours): This method compute the biweekly pay for this employee. Please note this method applies to both types of employee. For salaried employee, this is the prorated salary based on yearly salary(no overtime pay).
