Interner	Provides equivalent behavior to String.intern for other immutable types.
ListMultimap	A {@code Multimap} that can hold duplicate key-value pairs and that maintains the insertion ordering of values for a given key.
Lists	Static utility methods pertaining to List instances.
MapConstraint	A constraint on the keys and values that may be added to a {@code Map} or {@code Multimap}.
MapConstraints	Factory and utilities pertaining to the {@code MapConstraint} interface.
MapDifference	An object representing the differences between two maps.
MapDifference.ValueDifference	A difference between the mappings from two maps with the same key.
MapMaker	A builder of ConcurrentMap instances having any combination of the following features: keys or values automatically wrapped in WeakReference weak or SoftReference soft references notification of evicted (or otherwise removed) entries
Maps	Static utility methods pertaining to Map instances (including instances of SortedMap, BiMap, etc.).
Maps.EntryTransformer	A transformation of the value of a key-value pair, using both key and value as inputs.
Multimap	A collection that maps keys to values, similar to Map, but in which each key may be associated with multiple values.
Multiset	A collection that supports order-independent equality, like Set, but may have duplicate elements.
Multiset.Entry	An unmodifiable element-count pair for a multiset.
Multisets	Provides static utility methods for creating and working with Multiset instances.
PeekingIterator	An iterator that supports a one-element lookahead while iterating.
RangeMap	A mapping from disjoint nonempty ranges to non-null values.
RangeSet	A set comprising zero or more Range#isEmpty nonempty, Range#isConnected(Range) disconnected ranges of type {@code C}.

Table.Cell	Row key / column key / value triplet corresponding to a mapping in a table.
TreeRangeMap	An implementation of {@code RangeMap} based on a {@code TreeMap}, supporting all optional operations.
TreeRangeSet	An implementation of RangeSet backed by a TreeMap.
