JAVA CODE
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.java class you can download by clicking on the file name. 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 class by writing a program, ShiftSupervisorDemo.java for instance, that uses a ShiftSupervisor object.
TIP: Your ShiftSupervisor class should inherit from the Employee class which you have downloaded. You will have two private fields: salary and bonus in you ShiftSupervisor class. They are both Double data type. You will also have constructors in your ShiftSupervisor class that will call its super, Employee class's constructors accordingly. You may have tow constructors, one with parameters, one without. Your ShiftSupervisorDemo.java will have a main() method. Some ShiftSupervisor objects will be created in this main() method. You ma want to display these new created ShiftSupervisor object's information.
