In the same code that I used in

and

Running :-

    for(Course c: dao.getAllCourses()) {
        for (AltTeacherWithCourses tbc: dao.getAltTeachersByCourseIdSorted(c.id)) {
            Log.d("TEACHER_SORTC","Teacher is "   tbc.teacher.name   " Courses = "   tbc.courses.size());
            for(AltCourse course: tbc.courses) {
                Log.d("COURSE_SORTC","\tCourse is "   course.coursename);
            }
        }
    }

Results in :-
