For this task you will create a Subject class, whose instances will represent the subjects for study at a university. A subject will have a name, just a String, and a subject code, which is a six-character String. The first three characters of a subject code are alphabetic and the last three are numeric. The first three characters define the subject’s discipline area. A subject code must be unique.
You will also write a TestSubject class to test the use of your Subject class. In particular this will maintain an array of subjects. In order to manage the uniqueness of the subject codes, your program will need to display information about existing subject codes as well as checking that any new subject code supplied by the user is not the same as any existing subject code.
The following state and functionality should be provided for the Subject class:
To assist with managing subject codes and their uniqueness you will provide the Subject class with some class methods as follows:
Your TestSubject program will perform the following sequence of actions, using good design techniques such as in the appropriate use of methods:

Material to submit
The material to submit for each task is described in the section Assessment Information in this Subject Outline, under the heading Presentation.
Develop a set of classes for a college to use in various student service and personnel applications. Classes you need to design include following:
Write a test Java program named CollegeList that declares an array of four “regular” CollegeEmployees, three Faculty, and seven Students. Prompt the user to specify which type of person’s data will be entered (‘C’, ‘F’, or ‘S’ indicates CollegeEmployee, Faculty, and Student respectively) or allow the user to quit (‘Q’). While the user choose 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 CollegeEmployees, 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,” “Faculty,” or “Students.” If the user has not entered data for one or more types of Persons during a session, display an appropriate message under the appropriate heading.
Save the files as Person.java, CollegeEmployee.java, Faculty.java, and Student.java, and CollegeList.java.
