Question

write an employee class. the class will have the following fields. - Employee name - Employee number in the format XXX-L, where X is a digit within the range 0-9 and the L is a letter within the range A-M. - Hire date write "set" and "get" method for each field. write no args constructor. Write constructor that has an argument for each field. Next, write a class named ProductionWorker that extends the Employee class. The ProductionWorker class should have fields to hold the following information: - Shift (an integer) - Hourly pay rate (a double) The work day is divided into two shifts: day and night. The shift field will be an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write appropriate accessor and mutator methods for the class and no args constructor. write a constructor that has args for the fields. write an employee demo class that will contain a main method. the main method will create the following output -Employee John cena, ID : 123-A, hire date: 4nov 2010 -Production worker : Ibra Bou, ID: 654-R, hire date: 9 jun 1999, shift: 1, pay rate $14.50 In creating these Employees and ProductionWorkers, you must use all of the constructors and all the set and get method at least once. the main method in the EmployeeDemo class will calculate and print out the average pay rate for the Productionworkers.
