Answer: provided in the explanation section

Explanation:

Note: take note for indentation so as to prevent error.

So we import com.google.common.collect.Multimap;

import java.util.Collection;

import java.util.Map;

class Main {

public static void main(String[] args) {

// key as studentId and List of Profile as value.

Multimap<String,Profile> multimap = ArrayListMultimap.create();

multimap.put("id1", new ExamProfile("examStudentId1"));

multimap.put("id1", new ELearningProfile("userId1"));

multimap.put("id2", new ExamProfile("examStudentId2"));

multimap.put("id2", new ELearningProfile("userId2"));

// print the data now.

for (Map.Entry<String, Collection<Profile>> entry : multimap.entrySet()) {

String key = entry.getKey();

Collection<String> value = multimap.get(key);

System.out.println(key + ":" + value);

}

// assuming String as the studentId.

// assuming Profile as the interface. And Profile can multiple implementations that would be

// specific to student.

interface Profile {

}

class ExamProfile implements Profile {

private String examStudentId;

public ExamProfile(String examStudentId) {

this.examStudentId = examStudentId;

}

class ELearningProfile implements Profile {

private String userId;

public ELearningProfile(String userId) {

this.userId = userId;

}

This code is able to iterate through all entries in the Google Guava multimap and display all the students name in the associated students profile.
