Question

Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number and e-mail address. A student has a class status (freshman, sophomore, junior or senior). Define the status as constant. An employee has an office, salary, and experience (number of years, integer value). A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each of the class to display the class name and the person’s name.
