1. Guava/Multimap
com.google.common.collect.Multimap<K,V>

2. Map vs Multimap
Guava Multimap

3. Usage expample

4. Multimap structure

5. Interface hierarchy
Interface Multimap <K,V>

6. Implementations of ListMultimap

9. Compare to JDK Collections
Guava Implementation Keys behave like Values behave like
ArrayListMultiMap HashMap ArrayList
HashMultiMap HashMap HashSet
LinkedListMultiMap LinkedHashMap LinkedList
LinkedHashMultiMap LinkedHashMap LinkedHashSet
TreeMultiMap TreeMap TreeSet
ImmutableListMultiMap ImmutableMap ImmutableList
ImmutableSetMultiMap ImmutableMap ImmutableSet
