java simple association

I am trying to add an association between Course class and Lecturer class, but I am getting an error.What am I doing wrong?

I am adding this piece of code into the Course class so that for each course a cordinator is assigned.

public void addCordinator(Lecturer newLecturer){
    this.lecturer.add(newLecturer);
}

Im not sure how your application looks like, but if you have one class called Course, and one called Lecturer and you want to make it possible for a course to have one or more lecturers, you can have a arraylist<Lecturer> inside the Course class. It would look something like this:

public Class Course{
   List<Lecturer> lecturerCollection= new ArrayList<Lecturer>();

//this method will be called with a lecturer object
public void       addCordinator(Lecturer newLecturer){
   lecturerCollection.add(newLecturer);
}

so you are now able to store lecturers for each corse, so if you have a Course object named course1, you can simply call course1.addCordinator() to add one or more lecturers to each course. This is as much as I can help you with the current code you provided
