Employees example: Abstract class and interface. The classes below describe an abstract class named EmployeePerson and two derived concrete classes, EmployeeManager and EmployeeStaff, both of which extend the EmployeePerson class. The main program creates objects of type EmployeeManager and EmployeeStaff and prints them.
1. Run the program. The program prints manager and staff data using the EmployeeManager's and EmployeeStaff's printInfo methods. Those classes override EmployeePerson's getAnnualBonus() method but simply return 0.
2. Modify the EmployeeManager and EmployeeStaff getAnnualBonus methods to return the correct bonus rather than just returning 0. A manager's bonus is 10% of the annual salary and a staff's bonus is 7.5% of the annual salary.
