1. Design a class named SchoolAssociate and its two subclasses named Student and Employee. Make the classes Faculty and Staff subclasses of Employee.

a. A SchoolAssociate has a name, address, phone number, and email address. You do NOT need to verify the format of these strings except for email. Verify that the email string contains an @.

b. A student has a class status (UnderGrad_Freshman, UnderGrad_Sophomore, UnderGrad_Junior, or UnderGrad_Senior, Grad_Masters, Grad_Phd) and a major. The classStatus field should be checked to assure it is one of the 6 valid choices when passed into the constructor or the mutator method (setClassStatus()). The major field does not need to be verified.

c. An Employee has an office (room number) and salary. You do NOT have to verify the format of the office field when passed to the constructor or mutator. Assure that the salary is not a negative number.

d. A faculty member has the department the faculty belongs to and a rank (Lecturer, AssistantProf, AssociateProf, or Professor). Verify that the rank is one of the 4 values mentioned when passed into a constructor or the setRank() method.

e. A Staff member has a title. You do NOT need to verify the format of the Title string. All fields mentioned above are Strings except for salary which is a double and is specified in Korean Won. The strings for class status must match one of the six strings shown in the parenthesized list in 1.b. above. Office strings should be formatted <3digitnumber (100-799)> (e.g. A201, B419, C704). All of the members must be declared private!

2. Write appropriate constructors for each making use of the super class constructor to initialize fields belonging to the parent class. The constructor for each class should accept values for each member in that class (and its superclasses!).

3. Write accessor and mutator methods for each field. These methods should be in the appropriate class! A getName() method should be in SchoolAssociate() but one of the child classes. The getSalary() should be in Employee and getTitle() should be in the Staff class as additional examples. Override the toString method in each class to display the class name and the person's name. But for each child class add the following to the string: 1. For Student, add their class status and major

2. For Employee, add their office and the string Salary: undisclosed.

3. For Staff, add their Title

4. For Faculty, add their Department and rank

Note that Employee and SchoolAssociate should NOT print their class name since they are parent classes. However, their toString() methods are needed to provide some information (SchoolAssociate provides the persons name and Employee adds just the office and Salary strings.)

Write a test program is provided (TestSchoolAssociates.java). Look at that to assure you code your Constructor with arguments in the correct order. The test code will create various types of School Associates and print them out to show the .toString() methods work correctly.

Sample Output

The test code provided should produce the following output:

SchoolAssociate: email address invalid! Faulty: Invalid Rank!

Employee: Invalid Salary Student: Joe Cool Undergrad_Freshman CS

Faculty: John Doe Office: A304 Salary: undisclosed Department: Computer Science Rank: AssistantProf

Staff: Jane Kim Office: B401 Salary: undisclosed Title: Admin Assistant

Student: Mincheol Kang Undergrad_Freshman CS

Faculty: Terrance Stamp Office: A504 Salary: undisclosed Department: Computer Science Rank: AssistantProf

Staff: Tom Thom Office: B601 Salary: undisclosed Title: Admin Assistant

Student: Jim Bob Undergrad_Freshman CS

Faculty: Terrance Stamp Office: A504 Salary: undisclosed Department: Computer Science Rank: null

Staff: Tom Thom Office: B601 Salary: undisclosed Title: Admin Assistant
