Question

Smart College wants you to develop a set of classes for them to use in various student service and personnel
applications. Classes you need to design include the following:
?
Person – A Person contains a first name, last name, street address, post code and phone number. The class also includes a method that sets each field using a series of dialog boxes and a display method that displays all of a Person’s information on a single line at the command line on the screen.

? CollegeEmployee – CollegeEmployee descends from Person. A CollegeEmployee also includes a staff id, an annual salary and a department name, as well as method that override the Person methods to accept and display all CollegeEmpolyee data.
?
Faculty – Faculty descends from CollegeEmployee. This class also includes a boolean field that indicates whether the Faculty member is tenured, as well as methods that override the

CollegeEmployee methods to accept and display this additional information.
? Student – Student descends from Person. In addition to the fields available in Person, a Student contains a major field of study and a grade point average, as well as methods that override the Person methods to accept and display these additional facts.

Write an application named CollegeList that declares an array of four “regular” CollegeEmployee, three Faculty, and seven Students. prompt the user to specify which type of person’s data will be entered (‘C’, ‘F’, or ‘S’), or allow the user to quit (‘Q’). While the user chooses to continue (that is, does not quit), accept data entry for the appropriate type of Person. If the user attempts to enter data for more than four CollegeEmployee, three Faculty, or seven Students, display an error message.
When the user quits, display a report on the screen listing each group of Persons under the appropriate heading “College Employees” – in alphabetical order by their last name, “Faculty” – in alphabetical order by their last name, or “Students” – in ascending order by their grade point average. If the user has not entered the data
for one or more types of Persons during a session, display an appropriate message under the appropriate heading.
