UML: how to implement Association class in Java

Question

I have this UML Association class. Note that: horizontal line is a solid line and the vertical line is a dashed line.

 ---------                  ---------
|         


        

Answer 1

I know this question is very old but I have a way more convenient than embedding n..1 relations in the association class :

public class Transcript {
    //Transcript's properties
} 

public class Course {

    private Map transcriptsByStudent;
}

public class Student {

    private Map transcriptsByCourse;
}
