Question

Create java classes: Notice that this is a class hierarchy so some classes will build on (extend) other classes. Each class is listed along with its class data members (variables). All variables should be declared private. Do not change the names of the variables and make sure set and get methods are named following Java naming conventions. If you are unfamiliar with Java method naming conventions, you can use the built in code generator in Netbeans to generate the correct names for the setters and getters. In addition to the class variables listed below, you will supply the following methods for each class.

1) set/get methods for all variables. The set method will take one argument which will be the value to set the variable to. The get method will return the value of the variable. You can auto-generate these methods using the built in code generator in Netbeans.

2) toString This method will return a formatted string containing all of the values for the variables. You can auto-generate this method using the built in code generator in Netbeans.

Classes:

1) Person. var: name(string), address(string), socialsecuritynumber(string: format: 999999999), dateofbirth (string: format: mmddyyyy)

2) Student (extends Person). var: currentGPA(float), dateofgraduation(string), courses(array list.. this will contain a list of courses the student is enrolled in)

3) Faculty (extends Person) var: dateOfHire(String:(format: mmddyyyy)), salary (double), courses(ArrayList)(This will contain a list of courses the faculty teaches)

4) Classroom. var: roomNumber(string), roomType(String)

5)Course. var: room(string), coursename(string), courseNumber(float)

Explanation / Answer

Person.java

public class Person {
   private String name;
   private String address;
   private String socialsecuritynumber;
   private String dateofbirth;

   public String getName() {
       return name;

   }

   public String toString() {
       String cours = " ";
       for (int i = 0; i < courses.size(); i++)
           cours = cours + courses.get(i).getCoursename() + " ";
       String string = "Date of Hire: " + dateOfHire + " Salary: " + salary
