Design a class named Employee. The class should keep the following information in fields: Employee name. Employee number in the format XXXL, where each X is a digit within the range 09 and the L is a letter within the range AM. Hire date. Write one or more constructors and the appropriate accessor and mutator methods for 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 methods for the class. In a particular factory, a shift supervisor is a salaried employee who supervises a 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. 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 accessor and mutator methods for the class. Demonstrate the classes by writing a Java program that uses ProductionWorker and ShiftSupervisor objects.
