Not sure why this isn't working

Im having trouble with question 3 out of 5 I've been putting "Map<String, String>" But nothing seems to be working if anyone one can tell me what I'm doing wrong that would be amazing.

Because we are mapping Students to Grades and they have provided us with two classes named 'Student' and 'Grade' we use them as the Types for the Map. This will map 'Student' objects as the KEY and 'Grade' objects as the VALUE.

import java.util.HashMap;
import java.util.Map;

public class Main {
    public static void main(String[] args) {
        Map<Student,Grade> studentGradeMap = new HashMap<>(); 
    }
}

class Student {
    // omitted
}

class Grade {
    // omitted
}
