Question

Create a class named Person and its two subclasses named Student and Employee. Then create Faculty and Staff as subclasses of Employee. A Person has a name, address, phone number, and email address. Each of these will be String objects. A Student has a class status for a freshman, 2 for a sophomore, 3 for a junior, or 4 for a senior). An Employee has an office (String), salaryfint). and a date hired(String). A Faculty Member has office bJM&(String) and a rank (1, 2, 3, or 4). A Staff member has a title. Each class will have a method to display the name of the class and the person's name. For a Student, the method will also return the class status, for an Employee, the salary, for a faculty member, the rank, and for a Staff member, the title. Write a test program that Creates a Person, Student, Employee, Faculty Member, and a Staff Member. Sets values for all properties for a particular object (e.g. for a Student you will give the student a name, address, phone number, email address, and class status) Prints a string representation for each object, invoke their method. Notes: Give all instance variables protected visibility to allow access without setters and getters Use the default constructor for all classes Hard code the data in your programs e.g. Sam Bradford";
