Hi William Matheny

Actually it should be ravi because a Map is a Key and Value pair. So you should put in the key to get the value and not the other way round.

Please see the below code sample

Map<Student, Grade> studentGradeMap = new HashMap<>();
        studentGradeMap.put(ravi, B);
        studentGradeMap.put(sid, C);
        studentGradeMap.put(grace, B);

        Grade ravisGrade = studentGradeMap.get(ravi);
