Question

Design a class named Employee. The class should keep the following information in fields: Employee name Employee number in the format XXX-L, where each X is a digit within the range 0-9 and the L is a letter within the range A-M. Hire date Write one or more constructors and the appropriate accessor and mutator methods foe the class. 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 workday 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 one or more constructors and the appropriate accessor and mutator mutator for the class. Demonstrate the classes by writing a program that uses a Production object. In a particular factory, a shift supervisor is a salaried employee who supervises shift. In addition to a salary, the shift supervisor earns a yearly bonus when his or her shift meets production goals. Design a shiftSupervisor class that extends the Employee class you created in Programming Challenge 1. The ShiftSupervisor class should have a field that holds the annual salary and a field that holds the annual production bonus that a shift supervisor has earned. Write one or more constructors and the appropriate accessors and mutator methods for the class. Demonstrate the class by writing a program that uses a ShiftSupervisor object.

       System.out.println(ssv.toString());
