MY QUESTION IS
why address class and person class
keep telling me that THE TYPE ADDRESS(PERSON) is alredy defined
and how to fix it
and
can you help me to do Drive Class
Write a Driver class that maintains lists of Students, Courses, and FacultyMembers and has a menu that provides ways to list them and to create them and add them to the list. Provide ways to delete Students and FacultyMembers and for Students and FacultyMembers to add and delete Courses from their course schedules. However, you do not need to provide a way to delete a Course from the list of Courses.
Include a method that can be called from main that will use your methods to add and delete some hard-coded test data (several students, several faculty members, and several courses.) This will let you code the lists and test the methods to add and delete items without using the user input functions.
Do not create a new Course when a Student adds or when a faculty member is assigned to teach; let the user choose a Course from the list.
Solution
You have provided an extra parameter to the constructor of Address in FacultyMember class.
It should be
super(streetNumber, streetName, city, state, country);
not
super(streetNumber, streetName, city, state, country, name);
as the Address class takes only 5 parameters.
And your driver class should look like below
import java.util.List;
public class Driver {
List<Student> students;
List<classCourse> courses;
List<FacultyMember> facultyMembers;
//Add
public void addStudent(Student s){
students.add(s);
}
public void addCourse(classCourse c){
courses.add(c);
}
public void addFacultyMember(FacultyMember f){
facultyMembers.add(f);
}
//Delete
public void deleteStudent(Student s){
students.remove(s);
}
public void deleteCourse(classCourse c){
courses.remove(c);
}
public void deleteFacultyMember(FacultyMember f){
facultyMembers.remove(f);
}
//Show
public void showStudents(){
for (Student s : students) {
System.out.println(s.getName());
}
}
public void showCourses(){
for (classCourse c : courses) {
System.out.println(c.getClass());
}
}
public void showFacultyMembers(){
for (FacultyMember f : facultyMembers) {
System.out.println(f.getName());
}
}
}
and in the Main function you can add Hard coded values to test the class.
