Question

Develop a set of classes for a college to use in various student service and personnel applications. Classes you need to design include the following:

• Person — A Person contains the following fields, all of type String: firstName, lastName, address, zip, phone. The class also includes a method named setData() that sets each data field by prompting the user for each value and a display method that displays all of a Person’s information on a single line at the command line on the screen. For example, Joe Smith 111 N Student Way 88888 888-888-8888.

• CollegeEmployee— CollegeEmployeedescends from Person. A CollegeEmployeealso includes a Social Security number (ssn of type String), an annual salary (annualSalary of type double), and a department name (dept of type String), as well as methods that override the setData and displaymethods to accept and display all CollegeEmployeedata in addition to the Person data. The displaymethod should display the Person fields on one line, and the additional CollegeEmployeefields on the next, for example:

Jane Smith 111-W-College-Rd 88888 888-888-8888
SSN: 123-45-6789 Salary $80000.0 Department: CS

• Faculty — Facultydescends from CollegeEmployee. This class also includes a Boolean field named isTenured that indicates whether the Facultymember is tenured, as well as setData and displaymethods that override the CollegeEmployeemethods to accept and display this additional piece of information. An example of the output from display is:

Jane Smith 111-W-College-Rd 88888 888-888-8888
SSN: 123-45-6789 Salary $90000.0 Department: SE
Faculty member is tenured

Note: If the faculty member is not tenured, the third line should read Faculty member is not tenured.

• Student— Studentdescends from Person. In addition to the fields available in Person, a Student contains a major field of study (major of type String) and a grade point average (gpa of type double) as well as setDataand displaymethods that override the Person methods to accept and display these additional facts. An example of the output from display is:

Joe Smith 111-N-Student-Lane 88888 888-888-8888
Major: Biology  GPA: 3.47

Note: There should be two spaces before 'GPA' on the second line.

Write an application named CollegeList that declares an array of four “regular” CollegeEmployeeobjects, three Faculty objects, and seven Student objects. 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 CollegeEmployeeobjects, three Faculty objects, or seven Studentobjects, display an error message. When the user quits, display a report on the screen listing each group of Personsunder the appropriate heading of “College Employees,” “Faculty,” or “Students.” If the user has not entered data for one or more types of Personsduring a session, display an appropriate message under the appropriate heading.

The following are checked:

Define setData in Personclass

Define display in Person class

Define setData in CollegeEmployee class

Define display in CollegeEmployee class

Define setData in Faculty class

Define display in Faculty class

Define display in Student class

This has to be run in an online sandbox, JOption doesn't seem to work well with it. It appears to be searching for a specific pattern (like: super\.setData\s*\(\s*\))
